Absolutely correct, but once you start trying to cram wider rims on to take advantage of modern tires you can throw out the what should fit because you will be in new territory. My Duster has 15x7 aluminum wheels with 215/65R15 tires up front. Could I have done it in a 14” wheel and tire combo, absolutely, but finding wheels in 14” in the style I wanted is more difficult, and risk of not fitting for various reasons. One thing to think about is tire balancing… yup, that can screw it all up. I did not want wheel weights on the outside of the rim so my tire mounting shop went with the style that stick to the inside of the wheels, a much cleaner look. However that affects wheel to caliper clearance. Lots of factors, and no wrong answer, just possible interference once you start changing things around from factory.
