I have the stock alloy bullet hole rims on my f150. I beleive there 15x7? someone correct me if im wrong. First thing is i have 31x15x10.5 bf goodrich all terrains on them now and the rims look wider only a inch or so smaller then the 10.5" width of the tire but im pretty sure there stock by the looks? if they are stock whats the biggest tire that will fit on these rims? im wanting to put 33s on there next but im not sure they make 33s with that small of a width.

Not very common, but there are 33x9.50 tires.

33 x 12.5 x 15 will work on your wheels. This Bronco had them for many years before I installed 1 ton axles under it. They are not out of the manufacturer limits. Close, but still reasonable.

Next question, will a 31x10.5x 15 be ok on a 6 inch rim? Tom
