The Accelera PHI R is just like our PHI tyre, but with an updated tread design. An all-season performance tyre that offers excellent handling and stability, the PHI-R features a triple rib design and additional sipes to improve steering ability and reduce noise. The versatility of the tyre compound makes the Accelera PHI R an ideal choice for drivers looking for a solid everyday tyre or a tyre they can learn to race on. The PHI R can also be used as a street-legal race tyre for drift and track days.
