snow tires for 17" rims are much more scarce and more expensive. For that add'l cost you can get 16" rims and save the 17s from the salt...Originally posted by Killerfred:
This may be a stupid question, but why buy special winter rims? Are the stock rims not winter rims? Is there such a thing as winter rims? Enlighten me, please!
First # is section width of the tire. Second is the sidewall height in terms of % of the width, the aspect ratio. The last is the size of the rim. So a 215/45 17 is a 215mm wide tire, the sidewall is 45% of the 215mm, and fits 17 inch rims.Originally posted by Killerfred:
Another potentially stupid question... What do the three numbers mean?
