I got that. With a ten inch wheel, and 3.5 backspace and no lift he will rub the inner fender at the rear of the front wheel well, and rub the bumper valence at the front of the fender well. He will rub because of the backspace. What I left out of my post is that I rub with lift, 3 inches, and 1 inch wider, 1 inch taller tires, and a 3.75 backspace. He can run the 15x10 wheel, with a 31x10.50, he just needs more backspace, like 4.5 inches to keep from rubbing or to keep it to the minimum.DigEm - do you have a lift, or do the tires rub? I think this is what OP wanted to know...
It will really boil down to is how much crank will you need to clear.10 wides on stock hieght trucks are out thereOK. I went with a 15x10 with 4" BS. We will see how it fits. I am hoping a tbar crank and cutting the valance off will let me clear.
Also will it help that I am 4x4 and you are 2wd?
Thanks for all the info.
