[likibow]

Hi, i'm thinking of buying a 2008 sport trac and i want to get some 20 inch wheels but i dont know what's the biggest tire that i can purchase without having any issues with the inner fenders, i want to get some all terrain tires by the way, any help is welcome thanks!

I have had BFG 265/65/18 All Terrain TAs on the stock 2007 Sport Trac limited wheels since I bought the truck new. First set lasted about 65k miles. The rears will rub when fully loaded, ATV in bed, etc. but only on big highway dips or bumps. No rubbing at all with empty bed. Very happy with off-road traction and on snow covered roads. Not much of a mud tire but BFG makes those as well.
