Daily Driving a Square Suburban - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Every truck is a little different but I've gotten 32x11.5r15 and 33x12.5r15 on stock height trucks. I did have to hammer in the inside lip of the front fenders. And I also have to be a little gentle turning if the suspension is moving a bit, due to bumps. The rears tend to sag due to time, so adding a zero-rate lift spring helps level it out (1" block really).

I have a 2.5" lift and have 35x12.5r15's on stock rally wheels. No issues. I run 4.10's and it's pretty decent. Much better than the original 3.42's.
