Ratings & Reviews

Toyo Proxes RR

Good all around track tire. Lasts almost as long as the r888r, but much more grip. Not quite as sticky as a hoosier r7, but lasts longer.
Hal Mortimer
Great tires. These are the NASA Spec Miata dry tires and there's a good reason. I've been running a set of OLD ones since I bought my Spec Miata last year and they have handled pretty good. I'm looking forward to trying a brand new set next weekend to see what the difference is. By submitting a review, each person received a sweepstakes entry.
