DEPENDS.....Couple things here:
Depends on the tire not all tires are true to size, and also depends on if they are on factory or aftermarket wheels. Ex. I put on 28" Mudlites on my 06 on stock wheels and had extra clearance with no rubbing at all!! Then put on aftermarket wheels and 27" Laws and they rub on the fender brackets up front at full lock mostly with weight towards the front. 28's will work with either bending in the bracket or getting HL fender kit but you'll be starving for power in the thick stuff!!
