i was curious so i took a minute and layed under my rig with the tape measure its looking like the first thing you can hit with the tire back there is the bedside you have bout 14 inches from the bedside to the inner lip of the fender im running 15x10 wheels 5inch backspace 4 3/4 bolt pattern adapters to 5x5 bp with 295/50/15 MT tires i had to account for the adapter 1inch and the balooning of the tire 1 inch. there is still 2 1/4 inches between the tire and the first place it can rub on. {the bedside} the space looks huge in the pic but its 2 1/4 inches the front side it makes it under the fender the tire dosent stick out past the fender{pic2} but if i was trying to get the tire way up under the fender like some people do{which would be way too low for around here} id have to roll the lip of the fender more or get wheels with the 5x5bp and lose the adapters i would still be an inch and 1/4 from the bedside to the backside of the tire losing the adapters and gaining more backspace. the wheel are 15x10 but the tires add another inch on either side makes the width 12 inches. the trick would be to center that 12 inches in between the 14+ inches between the bedside and the inside lip of the fender pic 1 shows the space between the backside of the tire and the bed side pic 2 is a shot looking down on the fender showing the tire makes it under the fender pic 3 shows looking up at the front side of the tire and the fender lip {towards the right side of the pic} my truck is lower than stock but i still have 3 1/2 inches from the top of the tire to the fender-jeff
