The Grand Prix 4 Season is a top level racing clincher with exceptional winter and wet condition performance?
and further improved sidewall durability. The ultimate combination of speed, light-weight and wet weather performance, with excellent puncture and sidewall protection due to an ultra fine polyamide casing, added Duraskin^? sidewall reinforcement and black MaxGripSilica tread compound with specifically optimized for wet weather grip, low temperatures and extended tread life.

This tyre is based on the race-proven tread design of the venerable Grand Prix 3000 and so includes 5 carcass plies below the tread (3 for casing plus 2 anti-puncture layers) to give a total of 430 tpi plus Duraskin^? sidewall reinforcement beneath the tread.
