35x11.5 look great on stock wheels. IMO the 12.5's are just too bulgy

I agree!

Toyo at2s 295/60 on stock rims. Cognito leveling kit with uca's and Bilstein 5100s all around. Tires went on before leveling kit with no rub whatsoever on factory ride height. About 1/2 inch clearance at full turn

Thanks for all the info and photos guys , I have a black Denali like the photos and just posted a tread about tire sizes to see what fits . Thinking of Michelin 275/65/20s Lts or new series they have there spec is 34.1 height

Does the truck need to be re aligned after leveling the T bars adjustment screws ?

Yes, will need an alignment after cranking.

On stock wheels, 275/65/20 will probably fit without cranking. However, if you crank/level, then yes, you'll need an alignment.

It'll probably be off a couple mph......unless you get some kind of programmer to correct it. Whatever percentage you increase in overall tire diameter (from stock), is the same percentage that your speedometer will be off. For example, my truck is only slightly off at 50 mph......off 1 mph at 60.....and off 2 mph at 70.
