Wheel size
Most were 15x7.5
A 12.5 wide tire is not recommended for a 7.5 wide wheel. It can be done, but probably shouldn't. Plus in order for it to fit, you will need to lift your truck. 31x10.5 is about as big as you can go with stock suspension. And those will fit stock wheels. 32x11.5 will rub a bit, even with leveling springs.
