we used the 6" x 2" IFI wheels with rough top treads through 2 regional, champs, and 2 off seasons so far. We use a six wheel drive set up with a lowered center wheel. After two regionals we noticed that the centered wheel was pretty worn down. We purchased new treads but determined it would take too much time to change them at a competition. still with pretty worn treads we can still push around other bots just as well as day 1.
