20x12 wheels
Umm... Wheel width has something to do with how much the wheel "sticks out"... but what you are really looking for is WHEEL OFFSET.
The more negative the offset (-12mm, -44mm, etc) the FARTHER they will stick out from the fender.
The more positive the number (+1mm, +20mm, etc) the LESS they will stick out from the fender.

Most 20x12 wheels are going to come in really negative offsets such as -44 which causes the tires to stick out really far. You can get 20x10 with like a -19 offset for example and they won't stick out quite as far. Or you can do a 20x9 with a positive or 0 offset. Is your truck lifted if not a 20x12 would be out of the question anyways because there would be no way to clear them without some serious trimming
