You see, that was a key piece of info you left out. The OEM 17's and 18s are 7.5 inches wide with 5.5 inches of backspacing while the OEM 20's are 8.5 inches wide and have 6.5 inches of BS. This means the OEM 20's pull the tires in just a little farther than the 17's and 18's. That is why most 12.50 inch wide tires will touch the UCA/ball joint when mounted on the OEM 20's. With the OEM 17 and 18's, with a leveling kit, most 35x12.50's will only rub the control arms at full steering lock.
you seem to be pretty knowledgeable about this topic. I want to put Ballistic jesters on my 11 in a few months. I want to go with 305/55/20 Nitto Terras and Rims would be 20 x 9 4.5 BS offset -12. I knew to understanding BS and offset. does the lower # BS mean the tires would stick out further. Basically would this setup result in any rubbing issues. NOTE: I dont plan on putting a level on it anytime soon.
thanks for your help -

Not trying to be a moderator - sorry, but you may want to start a new thread for this, so this one stays on track. I will not go into any detail here, but check out this site https://www.rsracing.com/tech-wheel.html, I think it will answer most of your question to wheel fitment as far as specs go. In your new thread, we can discuss tire size options.
not sure how to make it a sticky?

Ok so with the OEM 18s and say a 1/4 inch spacer there should be no problems other than trimming which will happen regardless? If that's the case I may have to try it and then figure out how to post pics so I can show them

You are missing a factor with is the tire size. Could rub with a really wide tire.
