I have a 81 C10 Stepside. The truck was bought brand new by my grandfather. Originally a straight 6 3 on the tree it’s now a 383 stroker with a Th-350. The truck is lowered 2” in front and 4” in the rear. I have a pair of 17x9.5 Torq Thrust II’s for the rear. I’m looking for help with how big and wide of tire I can put on the rear. My next project is to put a 9” Ford rear ended under it and relocate the gas tank between the rear frame rails.
