Ok I have searched and searched and seen plenty talk about it but nothing that quite answered my question. I have a stock 2008 F150 FX4 SuperCrew with 275/55-20 on there right now and am looking to downsize to 18s and am not too keen on a leveling kit yet. If I were to downsize to 18s what would be the largest tire that I could fit with out having any rubbing when turning?

I greatly appreciate any help offered.

 

Depends on the wheel width and backspacing you use, but most 18's should allow you to fit a 285/65-18 (33x11.50) or 305/60-18 (33x12.50) without any issues.
