Ultra high-performance to a broader range of conditions with a reinforced casing, wider tread cap and dedicated Dynamic:Silica4 compounding to minimize rolling resistance while enhancing wet grip. Our Dynamic:Silica4 compound is formulated to minimize rolling resistance while enhancing wet grip. The R:Shield is a breaker belt found underneath the tread cap, providing an extra layer to improve puncture protection while maintaining optimal rolling resistance characteristics. Goodyear Bicycle Tires proprietary design that features all the benefits of a Tubeless Ready (TLR) tire but will also better maintain inflation pressure than a traditional TLR tire. A multi-compound material layer is added to our high-pressure Road-UHP tire casing allowing for improved air retention while providing additional puncture and cut protection with minimal increases in weight. Our unique design means more sealant remains after installation, ready for the moment you need it. To ensure the quality and safety of our tyres that we strive for at Goodyear, the fitment of the "Vector 4Season" tyres is close-fitting.
