For adventure and discovery:
Goodyear’s R: Wall sidewalls and Tubeless Ready construction ensure enhanced durability and fewer flats when the going gets rough. An all-around package of specifically formulated compound and casing means the County is a dependable component of your bike.
Construction: Tubeless Ready
Goodyear Bicycle Tyres’ proprietary design features a Tubeless Ready (TLR) tyre with additional air retention properties.
A Multi-compound material layer is added to the tyre casing, allowing for improved air retention while providing additional puncture and cut protection with minimal weight increase. Our unique design means more sealant remains after installation, ready for the moment you need it.
60-TPI casing:
Utilising a finer thread fabric, our 60 tpi casing uses less rubber – making the tyre more supple and faster rolling, with improved traction.
Under-tread breaker belt:
R: Shield
This is an additional puncture protection under the tyre’s tread cap. Tyres utilising our R: Shield offers excellent puncture protection while their sidewalls remain supple to ensure high performance.
