Competition

The contested ground

Prinx Chengshan sells tyres in over 160 countries through three channels — domestic distributors, international distributors, and direct supply to vehicle manufacturers — and manufactures from two bases, Shandong and Thailand, with a third under construction in Malaysia [1] [2]. Every rival in this tab does the same thing: five listed Chinese tyremakers, all reporting in renminbi, all selling all-steel radial (truck and bus) and semi-steel radial (passenger) tyres into the same export replacement channels, and all building capacity outside China. The overlap is close enough that the comparison is fair on scale, growth, margin and capacity; it is not fair on product mix, and the tab says where.

Management's own framing names the pressure precisely. The FY2025 report describes competition against "numerous global tire manufacturers while also facing challenges from Chinese tire enterprises," which "have accelerated their diversified production footprint by establishing new smart manufacturing bases in Southeast Asia (such as Thailand, Vietnam, Cambodia) and Eastern Europe (such as Hungary, Serbia)" [3]. That paragraph is new in recent vintage: it first appears as item (4) of the FY2024 risk section, which closes on the challenge of intensified competition in the regional market [4] and is repeated word for word in FY2025. The FY2023 risk section, by contrast, runs six items from macro environment through climate change and contains no competition item at all [5].

The evidence base for what follows: five annual reports for Prinx Chengshan (FY2021–FY2025), the 2018 global-offering prospectus (the only document in the corpus carrying third-party market-share and contract-term detail), and each rival's own FY2024 and FY2025 annual reports plus, for Sailun, four investor-meeting records. Arena structure and cycle belong to Industry; the raw peer source shelf is Competitors; company call commentary is in Calls.

Segment overlap

The staged peer screen named six Chinese tyremakers [6]. Five of them have annual reports in this corpus and all five are confirmed from their own filings as radial tyre manufacturers competing for the same export replacement shelf. The sixth, Zhongce Rubber Group (603049), has no indexed filings in this run, so it appears nowhere in the numbers below despite being China's largest producer by volume; that is a hole in the record, not a judgment that it does not compete.

Sources: Prinx Chengshan FY2025 Annual Report, production capacity and distributor channel revenue disclosure [7] [8]; Sailun FY2025 Annual Report, overseas layout [9]; Linglong FY2025 Annual Report, capacity table [10]; Triangle FY2025 Annual Report [11]; Guizhou Tyre FY2025 Annual Report, overseas base disclosure [12]; Jiangsu General Science FY2025 Annual Report, capacity table [13].

Two of the five differ enough in mix to make like-for-like margin comparison unsafe. Guizhou Tyre earns most of its revenue from off-the-road and heavy commercial tyres: it sold 9.65 million tyres in 2025 for RMB10.87 billion of tyre revenue [14] [15]. Linglong runs the opposite way — 91.3 million tyres for RMB24.47 billion, overwhelmingly passenger [16]. Prinx Chengshan sits between them.

Rival scale and profit, FY2022 to FY2025

Sources: Sailun FY2025 and FY2024 Annual Reports, key accounting data [17] [18]; Linglong [19] [20]; Triangle [21] [22]; Guizhou Tyre [23] [24]; Jiangsu General Science [25] [26]; Prinx Chengshan FY2025 Annual Report, revenue recorded for the year [27].

Over the four years, the set separates. Sailun added RMB14.89 billion of revenue and Jiangsu General Science more than doubled from a small base; Prinx Chengshan grew 44.8%; Triangle went sideways, from RMB9.22 billion in 2022 to RMB9.82 billion in 2025, with two consecutive declining years after a 2023 peak of RMB10.42 billion; Guizhou Tyre grew 29.7% but almost stalled in 2025 at 2.4%.

FY2025 was the year profit broke from revenue for most of the group.

Sources: as for the revenue chart above — Sailun [28]; Linglong [29]; Triangle [30]; Guizhou Tyre [31]; Jiangsu General Science [32]; Prinx Chengshan, profit attributable to owners of the Company [33].

Five of the six earned less in 2025 than in 2024 while five of the six sold more. Sailun's profit fell 13.3% on 15.7% revenue growth; Linglong's fell 21.9% on 11.7% growth; Jiangsu General Science lost 46.1% of its profit while revenue rose 22.1%; Prinx Chengshan's fell 17.1% on 7.6% growth [34]. Guizhou Tyre was the exception, up 0.7%. That pattern — volume up, unit economics down, across five independently audited filers in the same year — is the single most consistent fact in the peer record.

Sources: peer gross margins and geographic splits are the tyre or main-business segment figures each company reports under PRC accounting standards — Sailun [35], Linglong [36], Guizhou Tyre [37], Triangle [38], Jiangsu General Science [39]; Prinx Chengshan's is the consolidated IFRS gross margin [40] with the geographic share derived from its segment note [41]. Prior-year peer margins are derived from the year-on-year percentage-point movements disclosed alongside each FY2025 figure.

The accounting bases differ, and the difference matters: Prinx Chengshan's 18.1% is a consolidated IFRS gross margin on all revenue [42], while the peer figures are PRC-GAAP main-business margins that exclude some costs Prinx Chengshan carries above the gross line. Read the levels as a rough ranking and the year-on-year direction as the reliable signal. On direction, four of six compressed, Prinx Chengshan by 3.1 percentage points [43], Linglong by 4.95 and Sailun by 3.08 [44] [45]. Triangle went the other way, adding 2.11 points on falling revenue [46].

Margin by geography

Every rival that splits gross margin by geography earns more abroad than at home. Prinx Chengshan does not publish that split, so its bar is absent from this comparison.

Sources: Sailun [47]; Linglong [48]; Triangle [49]; Guizhou Tyre [50]; Jiangsu General Science [51].

The gap runs from 5.0 points at Sailun to 18.0 points at Jiangsu General Science, which reported a negative domestic gross margin of 2.67% on RMB1.15 billion of PRC sales in 2025 — selling at home below the cost of goods, on revenue down 4.7% year on year, while its export gross margin held at 15.31% on revenue up 28.7% [52]. Prinx Chengshan's domestic distributor revenue fell 10.6% to RMB2,078.9 million in 2025 while international distributor revenue rose 3.4% to RMB7,796.6 million [53]; whether its own domestic margin behaves like the peers' is not disclosed.

Offshore capacity

The capacity being built outside China is where the rival record is most quantitative, and where the scale spread is widest.

Sources: Prinx Chengshan Thailand capacity [54] and Malaysia plan [55]; Sailun overseas planned capacity [56]; Linglong plant-by-plant design capacity [57]; Jiangsu General Science plant-by-plant design capacity [58]. Guizhou Tyre discloses its Vietnam base and a planned Moroccan second base without per-line capacity for the existing plant [59]; Triangle discloses no offshore plant.

Sailun states in its FY2025 report that it has planned overseas capacity of 11.1 million all-steel radial tyres, 62 million semi-steel radial tyres and 110,000 tonnes of off-the-road tyres across five countries, and describes itself as "the Chinese tyre enterprise with the largest overseas capacity" (目前海外布局产能规模最大的中国轮胎企业) [60]. Prinx Chengshan's operating offshore capacity is 12 million sets in Thailand, with 6.6 million more planned in Malaysia at a stated investment of USD299 million, construction having begun in the third quarter of 2025 [61] [62].

Movement in 2025 alone: Linglong added 7.75 million semi-steel and 1.0 million all-steel sets of achieved capacity in Serbia [63]; Jiangsu General Science added 5 million semi-steel sets in Thailand and 0.5 million all-steel plus 2 million semi-steel in Cambodia while cutting domestic capacity by 1.2 million all-steel and 3 million semi-steel sets [64]; Sailun announced a 1.65 million all-steel expansion in Cambodia in January 2025, first output from its Indonesian and Mexican bases in May, and in August an Egyptian project for 3 million semi-steel and 600,000 all-steel tyres a year, expanded in April 2026 to a plant that would run 9 million semi-steel and 1.65 million all-steel tyres a year once complete [65]. Guizhou Tyre, which runs a "Guiyang in China, Dong Thap in Vietnam" dual-base strategy, states it is "actively preparing a second overseas production base, planning to invest in Morocco in an intelligent manufacturing project with an annual capacity of 6 million semi-steel radial tyres" (公司正积极筹建第二个海外生产基地，计划在摩洛哥投资建设年产600万条半钢子午线轮胎的智能制造项目) [66]. Jiangsu General Science publishes a target of five production bases, five research centres, 500 strategic channel distributors, 5,000 core stores and capacity above 50 million tyres — roughly double the 25.6 million it sold in 2025 [67] [68].

Prinx Chengshan's own utilisation ran tight in 2025 — Shandong at 93.8% all-steel and 92.6% semi-steel, Thailand at 80.6% and 92.5% [69] — against Linglong's Thai plants at 80.6% and 83.7% and its group design capacity of 125.6 million tyres [70]. Prinx Chengshan's total across both bases is 30.9 million sets.

Price per tyre

Volumes and tyre revenue are disclosed by all six for 2025, which makes average realised price per tyre computable on a common basis. It is a mix indicator, not a price-competitiveness score: a truck tyre and a passenger tyre sell for very different money.

Source: derived from disclosed tyre revenue divided by disclosed tyres sold — Sailun 81.13 million tyres on RMB36,403 million [71]; Linglong 91.35 million on RMB24,475 million [72]; Jiangsu General Science 25.59 million on RMB8,447 million [73]; Triangle 22.61 million on RMB9,759 million [74] [75]; Guizhou Tyre 9.65 million on RMB10,870 million [76] [77]; Prinx Chengshan 29.3 million on RMB11,807 million [78].

Prinx Chengshan's own blend of RMB403 decomposes into roughly RMB794 per all-steel tyre and RMB242 per semi-steel tyre, using the 56.5% and 41.8% revenue shares it discloses against 8.4 million and 20.4 million sets sold [79]. That spread explains most of the difference between it and Linglong, and all of the difference between it and Guizhou Tyre.

Across its own five years the blended figure has moved on a path of its own.

Source: derived from disclosed sales volumes and revenue, FY2021–FY2025 Annual Reports [80] [81] [82] [83] [84]; gross margins as reported [85] [86] [87] [88] [89].

Revenue per tyre peaked at RMB441 in 2022 and has run 8% to 11% below that ever since, with the 2023–2024 fall coinciding with the shift of volume towards semi-steel: semi-steel sales went from 11.5 million sets in 2022 to 20.4 million in 2025 while all-steel went from 6.7 million to 8.4 million [90] [91]. Gross margin and price per tyre moved together in 2022 and 2025 and apart in 2023, when margin rose 7.0 points as price per tyre fell — the company attributed that year's expansion to volume and falling raw material prices [92], and the 2025 contraction to raw material prices and United States tariff policy [93].

Disclosed share, and the years since

The only third-party market-share measurement of Prinx Chengshan anywhere in this corpus is in the 2018 prospectus, prepared by Frost and Sullivan on 2017 data with rivals anonymised. It is eight years stale, and there is no later measurement in any filing.

Source: 2018 global-offering prospectus, Industry Overview, Frost and Sullivan and China Customs data for 2017 [94]; the export ranking tables and their shares are on the following page [95].

The same section put the top ten domestic players at a combined 26.6% of PRC all-steel radial sales volume and 21.0% of the replacement market, describing a sector where "the majority of domestic players don't have considerable scales and thus they mainly compete in highly-competitive medium- and low-end tires segment" [96]. Triangle's FY2025 report says essentially the same thing eight years later: Chinese tyre companies are "numerous but individually small in scale, with insufficient industry concentration and pronounced tiering" (企业数量众多但个体规模偏小，行业集中度不足，梯队分化明显) [97].

What has changed and is measurable sits in three places. First, ranking: Sailun reports itself tenth worldwide and second in China on 2025 trade-press tables [98], Triangle eighth in China by 2024 revenue and twenty-fifth globally [99]. Prinx Chengshan states no ranking in any of its five annual reports.

Second, customer concentration, which fell by half and then stopped falling.

Sources: FY2021–FY2025 Annual Reports, Report of the Directors, top five customers and single largest customer [100] [101] [102] [103] [104].

The break falls between 2022 and 2023: largest customer from 9.1% to 3.6%, top five from 17.8% to 12.2% [105] [106]. At the 2018 listing the largest customer was Cooper Tire, taking 21.0%, 20.5% and 14.8% of revenue in 2015, 2016 and 2017 under two offtake agreements expiring 30 June 2019 [107]. No customer has reached even 4% of revenue since 2022. The filings do not name the customer whose exit produced the 2023 step down.

One rival does quantify what happened in the channel Prinx Chengshan calls home. Triangle reports that its PRC replacement volume fell 18% in 2025, passenger-car replacement volume 22%, and international volume 6%, while its domestic original-equipment volume grew 7.8% [108]. Prinx Chengshan does not publish volumes by channel, so its own domestic replacement trajectory can only be read through the 10.6% revenue decline in that channel [109].

Third, channel mix, which is where the actual sales fight shows up.

Sources: FY2021–FY2025 Annual Reports, channel revenue disclosure [110] [111] [112] [113] [114].

Domestic distributor revenue is the one line that has gone nowhere in five years: RMB2,043 million in 2021, RMB2,079 million in 2025, having fallen in three of those years [115] [116]. This happened while the company was adding channel infrastructure at home: the commercial-vehicle "lighthouse e-station" network grew to 8,078 stores from over 7,149 a year earlier, and 126 passenger-tyre distributors carried 25,389 registered retail stores [117]. Direct sales to vehicle manufacturers rose 73.9% in 2025 to RMB1,926 million, the fastest-moving channel, on new-energy heavy-truck and export-model programmes and mass supply to Great Wall Motor and SAIC Motor Passenger Vehicle [118]. Internationally the company added 56 distributors and entered five new markets in 2025 [119].

By destination, the Americas and the domestic market together account for two thirds of revenue and have alternated as the largest.

Sources: FY2023, FY2024 and FY2025 Annual Reports, segment information notes [120] [121] [122].

Trade-duty exposure

Duty rates are firm-specific in this industry, which makes them one of the few places where a rival's cost position and this company's are measured separately by the same authority. Prinx Chengshan's Thai subsidiary carried an average United States anti-dumping duty of 17.06% on passenger and light-truck tyres from the July 2021 order; the first administrative review cut that to 4.52% in its January 2024 final result, and the second review set a separate rate of 5.08% on 6 May 2025 [123]. On truck and bus tyres from Thailand the company was made a mandatory respondent and received 12.33% in the October 2024 final determination; South Africa's anti-circumvention case assigned it a preliminary 6.61% [124].

The open case affects the whole peer group rather than one firm: the European Union began an anti-dumping investigation into Chinese passenger and light-truck tyres on 21 May 2025, added a countervailing investigation on 6 November 2025, and from 22 January 2026 required import registration allowing retroactive duty [125]. Prinx Chengshan attributes the fourth-quarter slowdown in Chinese semi-steel exports to that investigation [126]. Jiangsu General Science frames the same mechanism from the other side, listing among its risks that alongside the United States' additional reciprocal and Section 232 tariffs and the European Union's investigation, "South Africa, Egypt, Brazil and other countries have also successively introduced tyre-related trade restriction measures" (南非、埃及、巴西等国也陆续出台轮胎相关的贸易限制措施) — the same countries in which Chinese tyremakers have been siting offshore capacity [127].

What rivals say

Each of the five describes the same arena, and the wording is worth reading because it comes from filings prepared independently for a different exchange and regulator. All five file in Chinese; quotations below are translations, with the original wording given where a phrase is load-bearing.

Sailun, on the reshaping of the field: leading overseas tyremakers are "gradually contracting strategically, divesting low-gross-margin business segments," while Chinese tyre companies, "driven by white-hot domestic market competition and increasingly complex overseas trade conditions" (受国内市场竞争白热化、海外贸易形势复杂化等因素驱动), keep pushing global capacity build-out and localised operation [128].

Guizhou Tyre, in its risk section, is blunter still: "domestic tyre industry capacity is structurally in surplus, competition is white-hot; the international high-end market is still dominated by industry giants" (国内轮胎行业产能结构性过剩，竞争白热化；国际高端市场仍由行业巨头主导), and "technology iteration and tightening environmental policy are accelerating the industry shake-out" [129], with survival pressure rising sharply for small and mid-sized enterprises while leading firms keep investing in overseas capacity expansion to consolidate their advantage [130].

Jiangsu General Science names the mechanism that shows up in its own negative domestic margin: structural overcapacity and rising manufacturing cost "bring price involution of homogeneous products" (带来同质化产品的价格内卷) [131].

Triangle attributes its own 2025 decline directly to the two markets Prinx Chengshan also sells into: production and sales volumes fell slightly year on year "affected by insufficient domestic replacement market demand and intensified international market competition" (受国内替换市场需求不足、国际市场竞争加剧等因素影响), with capacity utilisation about 90% and 22.61 million tyres sold [132].

On pricing, the most recent rival statement in the corpus is Sailun's investor meeting of 8 May 2026, where management said that after flexibly adjusting procurement and weighing production cost against demand, "the company has already raised prices on its products" (目前公司已对产品进行提价) [133]. A year earlier, on 21 May 2025, the same forum described capacity coming through in sequence: beyond the continuing ramp of Cambodian semi-steel, "the Cambodian all-steel expansion, the Indonesian plant and the Mexican plant are also expected to release capacity progressively" [134].

Prinx Chengshan's own reading of the same field, in its FY2025 industry section: reliance of the United States and Europe on imported tyres "continues to rise," Southeast Asia is "gradually replacing local production capacity in Europe, the United States, South Korea, and Japan to become a key source of supply," and Chinese producers' share in emerging and Western markets "continue to expand" [135]. The FY2024 report quantified the shift: overseas capacity as a proportion of China's top ten tyre companies rose from 18% in 2020 to 35% in 2023 [136].

Switching terms

The prospectus is the only document in the corpus that sets out contract terms, and what it describes is a low-friction channel: annual agreements, no minimum purchase obligation, cash before delivery, and distributor-set retail prices.

Source: 2018 global-offering prospectus, Business — Distribution Agreements [137]; Pricing and Payment Terms, where credit periods of no more than 60 days are granted [138]; the four-year warranty against defects in materials and workmanship [139]; the sales-area penalty and sub-distributor provisions are set out under Management of Distributors [140].

Nothing in those terms locks a distributor in for more than twelve months, and the prospectus records what that meant in practice: 82, 97, 140 and 74 distributors newly engaged in 2015, 2016, 2017 and the first quarter of 2018, against 66, 59, 75 and 26 terminated, mostly for missing sales targets or territory development expectations, with "top-ten distributors remained relatively stable" and no obligation to take back terminated distributors' unsold stock [141]. Gross churn of that size against a stable top tier is the pattern the disclosed terms would predict. Whether it still holds is unknown: no annual report since 2018 discloses distributor additions or terminations.

Two heavier contractual structures also sit in the record. The Cooper offtake agreements ran from 30 November 2014 to 30 June 2019 with annual minimum purchase volumes and monetary penalties on shortfall — penalties Cooper never triggered in 2014 through 2017 — and imposed sales restrictions barring Prinx Chengshan from selling semi-steel tyres into Canada, the United States and Mexico and all-steel tyres into North America until those restrictions lifted at the end of 2017 [142] [143]. Those were the only minimum-volume commitments the company has disclosed, and they are long expired.

The second is internal to the ownership structure. Because the controlling shareholder retained a Malaysian tyre business that "may constitute direct competition with the Group," the Deed of Non-competition of 10 September 2018 gave Prinx Chengshan a call option and right of first refusal over Chengshan (Malaysia), and an undertaking that the Group would be appointed its "sole and exclusive distributor" at cost-based pricing if that business began operating first [144]. The independent non-executive directors confirmed compliance with that deed for 2025 [145]. Separately, the Malaysian base the company is now building is its own, in Kedah Rubber City [146].

On the customer side, the same low-friction picture holds where it is disclosed: private-label framework agreements set estimated volumes with prices renegotiated quarterly against raw material costs, and either party may terminate on written notice if the other fails to deliver or purchase 80% of the annual volume [147]. Original-equipment supply works the other way, on qualification rather than contract: the prospectus notes that entering a vehicle manufacturer's supply system "requires an assessment period lasting many years" [148], and the 218 customer-specific products developed during the track record period [149], along with current programmes for Great Wall Motor, SAIC Motor Passenger Vehicle, Chery New Energy and BAIC, are project-level rather than volume-committed [150]. The domestic logistics fleet relationships — JD Logistics, KUAYUE-EXPRESS, Deppon and Dishangtie, where the company describes itself as a high-share supplier since 2022 — carry no disclosed term, duration or exclusivity [151].

Gaps in the record

Four absences shape what a reader can and cannot conclude from the above.

No current market share. The last third-party measurement of Prinx Chengshan's share is 2017 [152]. The FY2025 report asserts a domestic commercial all-steel replacement "market penetration rate that ranks among the highest in the industry" without a number or source [153], and its brand-value citation of RMB3.940 billion for 2025 measures brand, not share [154].

No geographic margin split for this company, where all five rivals provide one. No current distributor churn data, where the prospectus provided four periods of it. And no filings at all for Zhongce Rubber Group, the largest Chinese producer by volume and a named member of the peer screen [155]. Triangle's four indexed investor-meeting records contain no extractable text, so its management commentary here rests on the annual reports alone.
