Would Size 265/30/19 tires fit on my 2003 330ci on the rear?

Question

Also, would 225 fit on the front?

Answer 1

Sure, with the right wheel.

Answer 2

Technically they would fit as long as the car was standing still. But you would not be able to drive the car without the tires scraping up against the wheel well. Even if you put a spacer inside of the rear coil spring there is no way you will be able to prevent the car from "bottoming out" on the tire without doing a major alteration to the suspension.
