Ok well I’m running 315’s on my car with ZERO issues. Probably driving a narrow body unicorn….nothing worse than speaking from actual experience.
I'm sorry, did I say EVERYBODY would rub? Shit, do people even read anymore or just look for stuff to ***** about?
Are you running an 11 inch wheel? Nope, so your experience isn't exactly the same now is it? You are running an 18x10.5. A 20x11 (I'm going to assume replica wheel since he doesn't say he wants full off custom wheels) will fit different than what you are running. There are lots of people rubbing with 315's on their car. Their are known good and known bad combinations of tire and back spacing. Someone already posted a link to a good resource for the OP on that.
315 on a NB challenger you pose the risk of rubbing based off the wheel used, tire used and just the overall car. Some cars have more rubbing issues than others mainly due to how the cradle was installed (slightly off center for example). As such, and because I think a tire that sticks out past the fender looks silly to me, I will ALWAYS suggest to people asking for an opinion to go with 305. It's a safer choice for fit and going to a 315 over the 305 poses almost no extra benefit.
And before you go with your "experience" BS, try not to assume others haven't been down that same path and come to different results.
