RE: I have an idea has anyone....
You do know there is 2 different compounds for the tires right ? there is a hard for the front and a medium for the rear.
AS you run the truck around for a while, they soften up. My rears on the MT I drilled small air holes inthe rim and they are perfect with the foam insert except in hard lean turns as the outside rims on occasion as the sidewall gives toomuch scruff the ground, but it is because the superglue came loose and the tire "burps" out of the grove, and then goes back in once it is running straight again.
