I. Company Overview

CST Tires Founded in 1967 in Changhua County, Taiwan, China, it is a global leading tire manufacturer and the industry leader in the two-wheeled vehicle tire segment.

- Headquarters : Changhua, Taiwan, China; Mainland headquarters in Xiamen (established in 1989).

- Scale : Five global R&D centers, 22 manufacturing facilities, more than 23,000 employees, products sold in over 200 countries, and a top-ten global tire company.

- Positioning : Specializing in bicycle, electric vehicle, motorcycle, and automobile tires, with Wear-resistant and puncture-proof, with high cost performance. Famous.

II. Second-Generation Bicycle Tires: Core Technologies

1. Puncture-Resistant Technology (Defender EPS)

- Structure : High-strength fiber layer added to the tread/ sidewall (e.g., Twaron® ), enhanced puncture resistance 3–5 times 。

- Application : Standard equipment for urban and mountain tires, such as the CTC-25 and CRD-06, effectively reduces puncture rates.

2. Tire Body Structure (TPI/Number of Ply Layers)

-60TPI/120TPI : High-density curtain fabric, lightweight (weight reduction 15% ）、low rolling resistance (reduction 10%+ ), more comfortable.

- HL20 High Load Capacity : Reinforced carcass, increased load capacity 60% , compatible with E-CARGO/heavy-load scenarios (e.g., CTC-31).

3. Rubber Formulation

- DC2 high grip : Excellent grip on dry and wet surfaces, short braking distance, suitable for mixed mountain and road conditions.

- COREX Eco-Friendly Formula : Rice husk-derived white smoke replaces carbon black, reducing weight, rolling resistance, and carbon emissions.

- Self-healing i-sealant : The inner wall is coated with a polymer adhesive layer that automatically seals punctures up to 3 mm in diameter, preventing air leakage.

4. Pattern Design

- Urban Commuting : Streamlined grooves + diamond-pattern treads for rapid drainage and stable performance on wet surfaces (e.g., CTC-29).

- Mountain Off-Road : Large-block directional tread pattern for strong grip and excellent water drainage (e.g., CMT-12).

- Road Racing : Center smooth surface + low-drag sculpted pattern, resulting in low rolling resistance and high speed (e.g., CRD-06).

III. Product Iteration (1990s–2020s)

1990s foundational period : Mainly featuring the mainland’s first bicycle tire Wear-resistant and durable , steel wire carcass, simple tread pattern, suitable for commuting.

Functional period of the 2000s : Launch Puncture-resistant tire (First-generation EPS), mountain tires (with block-pattern treads), and lightweight road tires—each tailored to specific riding scenarios.

Performance Era of the 2010s : TPI upgrade: 60 TPI for mainstream use, 120 TPI for high-end applications, with lightweight design and low rolling resistance; E-BIKE-specific: enhanced load capacity and puncture resistance, optimized for electric-assist bikes (e.g., COREX).

The Smart Environmental Protection Era of the 2020s ESG Sustainability: utilization of renewable and recycled materials, with low-carbon emission reductions; Self-healing and Run-flat Technology: i-sealant and HL20 tire structure for enhanced safety; Specialized Product Segmentation: E-CARGO (CTC-31), Fat Bike (CMT-12), and Competition Road (CRD-06).

IV. Core Advantages

- Safe and Durable : Puncture-resistant and self-healing technology for a low puncture rate; high-abrasion-resistant compound for extended service life. 20%+ 。

- All-in-one compatibility : Full lineup for city, mountain, road, and e-bike applications, with a complete range of sizes (26”, 27.5”, 29”, and 700c).

- High cost performance : Performance on par with international top-tier brands, at a lower price 30%–50% 。

- Technical Barriers : Over 1,000 global patents, with continuous innovation in materials, structures, and formulations.

V. Overview of Representative Products

CTC-25 (Urban E-BIKE) : Double-layer carcass + TI3 + Defender puncture protection, 60 TPI, low rolling resistance, and excellent puncture resistance.

CMT-12 (Mountain Fat Tire) : Large off-road tread pattern, reinforced carcass, high-grip compound—stable performance off-road.

CRD-06 (Road Race) : 120 TPI+ TLR vacuum construction, low rolling resistance, lightweight, and high speed.

CTC-31 (E-CARGO Heavy Load) : HL20 high load capacity + EPS puncture resistance, DC2 formulation—strong and stable load-bearing performance.

VI. Summary

Zhengxin CST Relying on Deep technological expertise + full-category coverage + high cost-effectiveness , becoming a global leader in two-wheeled vehicle tires. Bicycle tires have evolved from basic wear resistance to Puncture-resistant, lightweight, low rolling resistance, eco-friendly, self-healing , iteratively refined to better meet cycling needs, it’s ideal for commuting, sports, and e-assisted riding. Safe and Reliable Choice 。
