18x9.5 +12

It's pretty obvious that in the rear I wouldn't be able to fit more than a 275. The front on a +12 wheel surprised me. I didn't figure that a fender roller would stretch the fender out that much. Although, my car is pretty low as is.

I'm thinking about upgrading at least tires in the near future, if not wheels too, but to play it safe I may end up going with a 265/35/18 as I want to reduce the likelihood of rubbing altogether.

That’s definitely a good plan. I know I always get caught up in running as much as I think I can fit the first time. But tires don’t last forever, running a little bit smaller than what you think is possible and going bigger next time around is a safer plan for sure. And with tires nowadays even if you don’t wear them out you’re buying a new set in like 6 years anyway.

Believe me, I’m not sure if anyone could be more surprised than me about those 18x9.5” +12’s. And I’ve rolled my front fenders already. I may not have pushed them as much because I was trying not to pop my paint, but still!
