It's time for new tires on my 2002 suburban, i would like to go a little bigger, was wondering how big you can get on a stock suspension2002 1500 4x4 suburban. Thanks, Russell

 

I put 265/75 on mine they are a little larger than the original. Lowered my rpms a little on highway, improved gas milage.
I believe it did affect my towing larger heavier loads, tranny wants to downshift alot, it cant seem to find a happy speed.

 

I have 265/60/r18 on mine seems to work ok its a 97
