315/70r17 on stock rims with 3.73 gears
Hi guys, i'm going to a local shop to get installed some 315/70r17 tires on my stock 10A Rubicon wheels, paired with some G2 1.5" wheel spacers. My 2013 jkur came with 3.73 gears. I know speedometer will be wrong, but what about shiftpoints since the Jeep is automatic? I already have an AEV procal, so i imagine i will have to measure the real tire height and enter it with gear ratio in the procal right?? Thanks in advance for some help..

Should be fine. Definitely use the procal. That should do it. Mine measured 34.5 when I put them on.. good luck with the wheel spacers, make sure you torque them correctly and see if they recommend locktite. And always recheck your torque specs after a couple miles. I'm ok with my 3.73's for now but I will be regearing soonish. Hopefully you have a lift to make sure those bad boys fit in the well..

Just make sure you measure the height of your tires at whatever psi you want to run and then program that height. I'm about to go up for 33's to 315/70r17's and I only have 3.21 gearing. I'll hopefully only have to put up with these gears for a year or so.
