Jim thats the combination i run on both my m04 and m03's, its perfect for carpet. If your stuck using tamiya tires only, put Type A's with hard inserts in the back and its very close, but the Type A's wear out very very fast. Thats why i LOVE these 3 racing tires. And I agree, they look disturbingly cheap (and they are cheap! lol) and they have a very hard feel to them, but i have no idea how they grip so well.
