I want to run 35"s or 37"s on my jeep. What all do i need to do i know ill need rims or spacers and regear? What size lift? i have I have 265/75/16 tires on it right now. How wide of rims can i put on these tires so i have nice rims for when i do the 35s or 37"s

 

Most people have a 2.5-3" lift for 35s. If you want 37s you will need flat fenders or at least 4" I believe.

As for regearing. Most people do but you can get buy with not regearing 35s for a while. You will probably want to regear soon after 37s.

I think people either go with a 8" or 10" wide rim on a 12.5" wide tire. 37s can sometimes be more than 12.5" wide so I would run a 10" wide rim.

 

What about driveshafts and axels. So can i run a 10" rim with what i have now as the bigger tires are a little ways down the road. i plan on using the flat fenders

 

do you have an automatic or standard? i cant remember the rules with a 2dr vs a 4dr and standard vs auto, but others will prob chime in.

I think it is safe to say less than 3" you dont need to worry about driveshafts.

 

there should be no reason why u couldnt put ur tires on a 16x10 rim un till u buy new tires.

drivshafts- 4 doors say u can get away with stock shafts up to 3", if u have an auto 4dr like me, u will end up tearing ur front driveshaft boot on the skid plate. so if u got the money a new front wont hurt, i plan to do it one day.

2drs need new driveshafts (recomended) with anything over 2.5" lift.

u can get 35" with a good 2.5" lift. 35" on a 3" for sure.

37's on a good 3" with some flat fenders and mabey wheel spacers. or mabey just the 3" and a 1" body lift. just extend the bumpstops also.

what mean by a good lift is like a teraflex will give u the lift hieght it says and +. ive heard of others like rough country only get 2.5" of lift from a 3" lift somtimes.

REGEARING

i have 35" and stock rubi 4.10s and a auto and its ok. i want to regear to 5.13's but its drivable as is imo. if i had 37" no way.

to get to the factory ratio on 35" go to 4.88's, i hear 5.13's is what most run to get more power than stock

37"s back to factory is 5.13's, i would go to 5.38's.

 

Putting 265s on 10in wheel will be pushing it. A 265/75R16 is roughly 31.5x10.5R16. They will go on, but there a good chance you'll damage your rims if you wheel it, especially in the rocks.

thanks for the advice. i have a 4 door 6 speed. Will probably wait on the rims as well and lift it and do everything at once
