CUSTOMWORKS REAR MOUNTED R2 COMPOUND TIRES (pair)

Derived from the popular "X" series of foam rubber compounds, the "R" series foam rubber has a better wear characteristic than the same density X2 but with slightly less grip at most tracks. The are a good choice for right side tires when X2's are wearing a little more than you would like. Also using them as a full set works very well when the track is tacky or wet and you need the car to roll easier and not be "stuck in the mud". Just like our other popular foam racing tires, the "letter" indicates the rubber type and is followed by a number that tells you the density rating of the foam compound...so the higher the number the greater the density.
