All foam tires are mounted on high impact Nylon rims. The top US brands of foam tires for sedan are JACO, Parma, BSR and CRC.

Note that there are a series of foam compounds for nitro asphalt racing and a different series for carpet racing. Each type is optimized for the its type of racing.

Nitro tires have a higher rubber content and a different foam struture.

Carpet tires are sold by color dot ratings. (Pink, Double Pink, Cyan, Magenta, etc)

Nitro tires are sold by numerical shore (hardness) rating. (30S,35S, 37S,etc)

Carpet tires work on asphalt but wear fast.

Nitro tire don't work well on carpet under normal conditions. They need heat to get traction and if you use traction compounds they get gummy and too much traction.
