so im going to do a 3in body lift on my truck and i want to run a true 33x12.5x17 tire on my truck. what backspacing/offset will i need to make these tires not rub? I was looking at the general grabber at2 and i can only find a load range C i would like a load range D since thats what my door sticker says. and my GVWR does not exceed the load range for the tires. and i can run 50 psi in them like my door sticker says. do you think i would be ok?
