Hmm thats a hard one. I would say OUTLAWS. Depending on what kinda mods your going to do or already have done I would say you would be safe with some 26x10x12 and 26x12x12
Yeah even a stock Foremanshould handle them. Make sure to get the XTs (Deep Lugs)10s and 12s I would go with 27s though. the Foreman can handle it for sure.
