great to hear that you are trying out the retreads....remember to take your wheel weights off once ya get them mounted....and DONT balance them.......i also wondered about the green diamond tires, but they were more money.....i paid $250 for the whole tracker, i didnt wanna pay a ton more for my tires than the whole damn trucklet...so i went the cheapest way out....by the way...i've noticed that the tires seem to need a crotch hair more air than normal tires....i run mine at 26psi, and she still rides like a hillbilly cadillac!
