Do I need to Regear for 35s?
285/70-17 is 102.8″ in circumference. 315/70-17 is 108″ in circumference. So we know that the 35″ tire is 5% larger in circumference and to maintain stock performance, we need a gearset that is 5% lower. So to maintain stock performance with a 35″ tire, a 4.30 gear is needed.
How much does it cost to change gears on a Jeep Wrangler?

How do I find gear ratio?
To calculate the gear ratio: Divide the number of driven gear teeth by the number of drive gear teeth. In our example, it’s 28/21 or 4 : 3. This gear ratio shows that the smaller driver gear must turn 1,3 times to get the larger driven gear to make one complete turn.
