Putting some 31"s on my stock grand cherokee. Anyone done this or know if I am going to have a rubbing problem, all input in greatly appreciated.

 

If you have zero lift and put 31's on you will rub very badly. You need to do a 2" Budget Puck lift to clear 31's..

 

What did these dudes come out with, 28-29's? That's why it took so much of a lift to put 38.5's on my XJ lol. BB lifts aren't very bad on the pocket book.

 

under normal street driving you shouldnt have a problem but when you go off road you will rub.

 

Ive seen plenty of stock ZJ's runnin 31's with no issues...and some that did...so just do a little trimming if needed

 

well in comparison, what size (28,29,30) is a 225/75 r15?

 

28X9

 

ok, cause even i am running bigger than normal (slightly) cause stock on mine is 215/75 r15, so a 30 is a huge wheel increase.

thanks, i was trying to wrap my head around the size difference

 

i often use the tire size conversion calculator at---> http://www.redrock4x4.com/tech/tire_calc.php

 

woo hoo 28.3" tires!

 

ok I have a 03 wj can i put 31's on it stock

 

correction, they are 30's so they look like they will clear all right, anyone know if they will rub or not?

 

From what i've seen if you go any bigger than 29's on a ZJ they will rub. Even with just road driving. That's what I've seen not a guess.

NOW if you have a upcountry pack on your ZJ than you can get away with 30's.


As for the WJ that I could not say, I know very little about them other than I would like to buy one some day.

 

What changes with the upcountry pack, mine is just a limited

 

UpCountry is a stiffer coil and gives about 1" lift over stock..
