4. Easy handling in urban use
Features of pattern design
GPR-300F
GPR-300
Easy handling in urban use
Constant distribution of pattern stiffness
for easy direction changes
Reduced pattern stiffness
(more grooves) for lighter steering and optimized grip.
Specific groove distribution
for improved anti-hydroplaning and wet grip
Hydroplaning testing

Improve wet grip
chemically, polymer and silica are bound stronger than polymer and carbon black
higher mileage
Silica is not bound directly to polymer, increasing compound elasticity
better wet grip

6. Features of casing construction Target: Easy handling and Ride comfort
improve stability
“APEX-LESS” construction
Maintain acceptable groove depth and reduce weight.
Light, effortless handling
Improve performance at Speed level in casual use (Less than 200km/h).
Bead reinforce Rubber(APEX)：Effects for High-speed stability but negative for Handling/Ride comfort at Lower speed level.
”APEX-LESS” construction, for comfort-optimized sidewall stiffness.
