Toyo Proxes RA1 Overview

An advanced racing tire inspired by years of winning and redefining the parameters of what a quality high performance tire is, the Proxes RA1 is specially engineered equipment for demanding drivers with high expectations. The durable R compound is soft for exceptional handling, but strong enough to withstand extreme usage. RA1 tires feature enhanced grip with greatly improved handling and steering abilities. A larger tread area and limited void enhance dry traction while the patterned groove arrangement assures wet handling as well. Tread depth indicators in the tire compound assist with greater control over tread wear and replacement.

Purchased tires to race in the SSM class. Compared to the SM7's there is minimal drop in grip and a huge improvement in the life of the tire. These tires will last almost the entire race season. I will add that the customer service at Simple Tire was awesome and the shipping was fast. I received my tires in just two days!
Super sticky tires!! Not great in the wet but if your careful not too bad. By submitting a review, each person received a sweepstakes entry.
Cuts time about four to five seconds and grips the road great. The next best thing to a full fledged race slick! By submitting a review, each person received a sweepstakes entry.
