I have a 2017 Chevrolet Silverado 1500 Z71 4x4, and I just had the Bilstein 5100 self leveling shocks/struts installed at the highest setting (1.85") on the front. After having the 5100s installed and getting it aligned directly after installation, the sidewall of my factory tires (265/65/18--31.6" tall x 10.4: wide) on my factory stock 18" rims are now very close (1/8' or less) to rubbing my upper control arms at full tilt. Also, I have no other blocks or lift on my truck whatsoever. I see countless people online saying they put 275/70/18 (i.e. 33" tall x 11" wide) on their stock Silverado rims with no rubbing issues with 2" leveling kits and/or the 5100 leveling shock/strut, but with my stock 265/65/18 tires are already on the verge of rubbing my upper control arms, and the 275/70/18 is over a half inch wider than my factory tire. I feel certain the 275/70/18 will rub the upper control arms. I like the factory rims and don't really want to buy new rims, and I am also would like to avoid using wheel spacers. What and I missing here? Has anyone else run into this issue? I did a lot of research and thought the 275/70/18 would fit without rubbing, so I am really disappointed. Thanks for any help/advise!
