The Vector 4Seasons Ultra High-Performance road tyre utilises the latest developments in materials and construction methods to optimise performance and protection across a wide range of wet and dry conditions. The Vector 4Seasons features bead to bead Armor protection, R:Shield under-tread breaker belt and Dynamic:Silica4 compound for improved wet grip and durability. A clincher tyre that is only functional with an inner tube to maintain inflation pressure as defined by ISO 4223-1.The historically standard bicycle tyre relies on the use of an inner tube to maintain inflation pressure. The inner tube serves two purposes: maintaining inflation pressure and providing physical pressure on the tire?s bead against the rim hook and sidewall to help keep it safely in place. Combining excellent anti-cut properties with minimal impact on casing suppleness and weight. Armor Protection enhances the Vector 4Seasons UHP road tire?s capabilities. The Vector 4Seasons brings Goodyear 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.
