Whats the Best Tire/Rim size for 2008 Sierra?

I’ve learned that the 15x10 inch rims do not look good on newer style trucks like it did on the old square bodies. What size rim and tire on a stock truck of this generation do you run?

Best tire/rim size is completely subjective and comes down to the wants of the owner.

 

Someone with stock height is going to want stock sized tires. Lowered and lifted trucks can change that size.

 

265/65/18's are the factory sized tire and so were 275/55/20's.  Going much bigger than a 32-33in tire will cause rubbing on stock ride height. I've run both of those size tires on previous trucks.

For what it's worth I changed my factory 17" SLE rims and tires for a 20" set of factory Denali rims and tires because I liked the look of them better, but they ride like crap. The Denali suspension is different than mine.

Will the 275/55/20 on 20x10 rims cause any rubbing on a stock truck? I’m trying to get that old school look where the tire sticks outside from the body a bit and is wide enough to look like some type of racing slick from behind if that makes sense. Thank you!

Factory sizes were P265/70R-17, P265/65R-18, and P275/55R-20.  The 17 inch factory wheels were 7.5 inches wide, the 18 inchers were 8 inches wide, and the 20 inchers were 9 inches wide.  If you stay with those factory sizes and wheel offsets (available online), you won't have any rubbing.  The 17 inch tires are generally less expensive, have more brands available in that size, ride softer, and offer better flotation for off-road use.  The 18's and 20's generally handle better, ride rougher, cost more, and have less brands available as you go bigger.  You have to have at least 17 inch wheels to clear the factory disc brakes up front.  If you ever use tire chains you'll want to go with the 17 inchers.
