Tire Sizes

[Wraypau]

I recently purchased a 2017 Sierra 1500 SLT. I want to put some better looking tires on it, what is the max height I can get, without scrubbing? 275-55 R20 ? Can I mkove up to a 275-60 R20, if I do move up, what will I ahve to do? Add lift keys to vehicle?

1500 lifts with top or bottom strut spacer.

2.5" is overall the most you want to lift the front with a spacer. I read recently 2017 are better off with top strut spacer and pick the tire of your choice then look under tire specs and try to stay between 33"x12.3"

My 2017 has a 2.5" front lift and 2" rear in replacement of oem 1.25" block and my federal couragia mt (32.8"x12.3") would rub a tad on the UCA stamped steel; so i had to add a 1/4" wheel spacer which solved my issue.

Where did you get your spacer from? Is one brnd manufacturer better tan the next? I just want to add a little height and a little more aggressive tire, but I don't want to add a body or suspension lift.
