tire stretch on AWD

goldsteina9 · 04-12-2012, 05:59 PM

just curious if anyone knows if running a 235 35 size tires square on all 4 corners could damage my transfer case. trying to run stretch and keep my my AWD system from getting destroyed. i figure since its the same rolling diamter for each corner it will be ok i just want to make sure

I assume u have 19's?? I have same setup. I'm gonna go with 255/30/19 all around. U can try 245/35/19 but rear might not fit.

It's not your transfer case you have to worry about.
Keeping the stock diameter is your biggest priority!

You can run any size but keep the outer diameter. Your sensors all run off wheel speed so you have to make sure they are getting the right signal!
