Wrong Tires?

What are the implications of running 245/45R/17 on oem 17" rims style 157 for my 328i base cabriolete?

The sidewall will deform over the edge of the wheel more since they're a bit big for the wheel, though unless you're tracking it, you'll be completely fine.

Thanks Heel Toe, I recently bought replacement rims and the dealer had me order new tires on my own (to get the discount). I did a typo and ordered the wrong size, they installed them anyway and didn't raise any red flags. Only after they were installed did I realized they were not the recommended size for my car/rim. They look slightly large, but they do ride a lot softer, appearance doesn't bother me too much. I just don't want to wreck my car or endanger myself by using the wrong size. Dealer says they work. I'm not racing or anything, so sounds like I'll be ok.

If your tires rub on a full turn or when you hit dips or speed bumps, it can chew up your tires. Have you experienced any rubbing?

Yeah that sidewall size seems a bit large. I think stock is usually 35 and 30 but I could be wrong
