Semi-Slick
SP-01R
Semi-slick. Street legal. Track ready.
The SP-01R is a high-performance semi-slick built for drivers who demand circuit-grade grip without sacrificing road manners. An aggressive directional pattern with minimal void clears water on the commute, then bites hard when the lights go green. Fast warm-up, stable shoulder blocks and a race-bred compound deliver predictable turn-in and consistent pace lap after lap.
