If you're staying with 33's I'd save the money and not re gear.
Thanks

I was referring to his math. For you u take your new tire size of 35. Divide by 32 then multiple by stock gear. I have 3.73 stock which means I need just over 410s. I'm going to go 456. Keep in mind also that your stock 3.21 have no business being in a jeep. They are the stupidest gear ever put in a wrangler.

Don't mean to hijack the thread, but I was curious how it was with 35s and 5.13 gears. I want to regear soon. Did you notice much difference, like did the Jeep pick up speed a little faster?

Regardless of the stock gear ratio, i'd look at the gear charts for your model. They use transmission gear ratios for your model with corresponding engine rpm's.

If it was me I would go with 4.56 with 35/37s on a 2012+ jeep if you spend time on road. 4.88 if a lot off road or hill country. If going larger than that tires you have much more to worry about

I wheel my jeep often and live in the foot hills of Appalachia I run 35" bfg km2s with a six speed and 4.10s I love it I don't feel as I need a deeper gear set, and despite all the warnings and naysayers when these 35s are gone it's getting 37s bolted back in their place.
