I wanted to start this to discuss tire types, compounds, etc. 1. What type of tires do you use? (rubber, PVC, Yokomo, etc.) 2. What compond tires do you use? (applies to rubber only) 3. What type of inserts do you use? (applies to rubber only) I use Tamiya radials (the ones that come on RTR TL-01 mustang and lightning) with no inserts.
