CST Tirent Tanwall Gravel Tire

A proper gravel tire from the world's largest tire factory. Built tougher than the price suggests.

The CST Tirent is a purpose-built gravel tire from Cheng Shin Rubber — the world's largest bicycle tire manufacturer — designed specifically for the 700x40C size that has become the de facto standard for gravel riding. Based on CST's proven B-Fast road model with refined shoulder variations for smooth cornering transitions, the Tirent is built from the ground up for dirt and gravel roads. With dual compound construction, EPS puncture protection, and the classic tan sidewall finish, this is a seriously well-specified entry-level gravel tire.

Why Riders Choose the Tirent

Dual Compound Tread The dual compound construction uses a fast-rolling centre compound for speed and efficiency on firm surfaces, with a different compound on the shoulder blocks to maximise grip when cornering. A meaningful upgrade over single-compound tires at this price point — most entry-level tires skip this entirely.

EPS Puncture Protection — Included as Standard EPS (Exceptional Puncture Safety) offers an added layer of proprietary rubberized poly-fiber material between the tread and the casing. The tight weave of this lightweight, puncture-resistant layer prevents foreign objects from penetrating the casing and damaging the tube. The kind of protection that used to cost more — here it's standard across the entire Tirent range.

Built by the World's Largest Bicycle Tire Manufacturer CST tires are produced by Cheng Shin Rubber, the world's largest bicycle tire manufacturer — a company that supplies OEM tires to global bike brands and has decades of engineering depth behind every product. The Tirent benefits directly from that manufacturing expertise.

40C — The Gravel Sweet Spot 700x40C delivers the right balance of rolling efficiency, traction, and comfort for mixed-terrain riding — wide enough to handle gravel, loose dirt, and light trail surfaces with confidence, narrow enough to roll efficiently on road sections in between. Compatible with most gravel, adventure, and hybrid bike frames.

Classic Tanwall Aesthetic The natural tan sidewall gives the Tirent a premium, performance-oriented appearance that stands out from standard black-sidewall tires — a look traditionally associated with higher-end racing rubber, here at a practical everyday price.

Important Note

The C-1870N-5 is the wire bead clincher variant of the Tirent — it requires an inner tube and is not tubeless ready. For a tubeless-compatible option, see the Maxxis Rambler TR in our gravel tire range.
