Part 1Refresh my memory but is wheel width 8.5".

Part 2
No issues with a 285/55R20 on the stock wheel right? Barely taller than facotry rubber, but ideal width is for 9.0" wide wheel. But should work on 8.5 right?

I recall someone saying you could go up to 325/??R20 on the factory wheel, or maybe that was the biggest rubber (w/aftermkt wheel) without serious issues.

I'm thinking if I had issues I could throw on the bilstein 5100s and raise it 1".

Thanks in advance!
