Just wanted to ad something to TigerRyans comments. You said you ran full sized tires. Tire wear gets less the smaller your tires get. The foam becomes more dense. If you run full size tires you will wear them very quickly and usually not evenly. You also run the risk of having them chunk easier. And the side walls will flex. Its much like real cars. Low profile tires are what you want for racing. Hope this helps. Hey Kaybo and Ryan, congrats on the sponsorship!
