I finally got my tires/inserts finished.Using type A. I had hpi mini soft blue shaped inserts in first, then I cut about 1/2 inch of the stock foams then glued them together. I placed the stock foam over the rim[tight fit] and slowly inserted the rim in the tire. Even though I used soft hpi insertd[blue]. The tires still feels firm with the foam combo. Only drawback is it is heavier.Hoping this would be my TCS front tire. Tried the rear with same type A but with stock foam inserts only. It was still too grippy. Tried the radials at the back with foams and that was tghe perfect combo with the front insert/foam combo. Anybody else have the same setup for the tires/inserts?
