Description

The Bridgestone Potenza RE050A is a max-performance summer tire, with a Scuderia version developed as original equipment for a high-profile Italian supercar. It gives strong traction with responsive, predictable handling on dry and wet roads.

A high-grip compound in an asymmetric tread, plus stable outboard shoulders and a continuous center rib, supports high-speed stability, while grooves pump water away.

The 215/40R18 size carries the 85Y load and speed index. It offers 10/32-inch tread depth, a 51 psi maximum inflation pressure, a UTQG rating of 140AA and an overall diameter of about 24.8 inches. This size is a run-flat tire.
