I just bought a 07 Suburban z71 4x4 that needs new tires. It has 265/65r18 and wondering how much bigger I can go and not rub? Looking to see if there are cheaper or different tire options going a tad bigger.

I’m on the fence with going Michelin Defenders M/S (I’ve had them in the past) or go to an all terrain. How quiet are the newer Cooper AT3 4s? I’ve ran the Hankook ATM in a 36” on an Excursion that I loved but they stopped making them. Now it’s a AT2 version. any recommendations on an all terrain that’s not overly aggressive but rides smooth/quiet? Thanks

 

Welcome to the forum.

I'm not sure but you could try checking with Tire Rack to see if they can answer your question about non-stock tires.
