[Redneck 91 YJ]

howdy all..... i just bought a 91 YJ Sahara with 31x10.5 tires and rims..... here is my issue.. can i put 33x12.5 tires on 10.5 rims... i know it will balloon the tires a bit and i know i have enough lift to put 33's on without rubbing..... just need to know about putting wider sized tires on thinner rims.... has anyone done this to theirs with any problems?? THANKS

oh yeah....you can actually put 33x12.50's on a 8'' wide wheel. the thinner wheel will actually help hold the bead on when you air it down!

SWEET....... THANKS........ I'VE DONE IT WITH 48'S BEFORE but that was on a ford pickup so just checking thanks...... and awesome discussion forum too!!!!

drew and his taco run 15x8's on 33x12.50's and josh used to run 15x8 on 33x12.50's before he got new tires and wheels...neither had problems

I have 33's with 15X8 rims and I think it looks great. I wanted extra protection on the trail since I went with the MT classic II's.

while we are on the topic does anyone know if 35x12.5's are good on the 8x15? 37x12.5?? if not would something like Staun internal beadlocks keep the tire on better?

 

[khenderson]

not sure about the 37's, but 35's will run nicely on 15x8's. i'm pretty sure Jerry Bransford runs that.

Thats great since im getting some 35x12.5 PJs when my 33's wear out most likely it would be bummer to have to buy new rims for 35's

 

[mrbigjeep]

yeah and i know rigs in mags run x8 wheels on 37x12.50's

Yeah, you can run anything that's a 12.50 on an 8" rim. However when most people start moving up to 37's they tend to also start increasing rim size to maybe a 17x9 or 17x8. 37's on a 15" rim leaves a lot of sidewall.

The biggest reason for getting larger diameter wheels after 37" tires, is because you would usually put in 1 ton axles at that point. To clear the brake assembly, it is preferred to go with the 16.5", or 17" wheel. Going with the 17" wheel will give you more choices of tire manufacturers. I have read about people that have shaved their brake rotors to allow for 15" rims. There is nothing wrong with a lot of side wall. Gives you more cush for the crawl. I have 14.5" wide tires mounted on 9" rims. The general rule of thumb is the width of the rim, will handle up to 4" wider of a tire. That of course can be strecthed a bit, if you use bead locks.

thanks for the info, if i decide to go up that big i will jus get inner beadlocks to make sure the tire stays on instead of buyin new wheels
