i did 18x10 +26 245/40 with a roll and pull and relocate...
18x10 +45 with like 255 no worries too
18x9 +26 up front i think it was 235...that worked fine until i went up a gutter wrong...flared my fenders for me lol

you can fit pretty much anything you want within reason...just depends on tyre and how u plan to drive.
