Tire size program

While looking for information, I came across this program for selecting tire sizes. If you are changing rim sizes and want to maintain your ratio on tires, this program is fantastic! It is free. It has many options and a graphic interface.

Go get this and never worry about tire size again.

If you are looking to change OE wheels with different models, or go aftermarket with larger wheels, here are some links charting BMW models, OE sizes and offset references.
Hope it helps.
