[QUOTE="Sleepersilverado, post: 1515086, member: 10484"] Hopefully mine don’t rub with the 3 link. I think what shef was saying is to run the tire size up to the max in the computer then trick the truck by changing the gear ratio in the computer. Simple online calculator says from factory tire to 37 would need to change back to a 3.85 gear ratio. Shows effective ratio of 3.27 with new tires. [/QUOTE]
