Help with swapping winter tires

[nulyen]

Hello,
I just got a 2002 Saturn LW300. It has tires of size 205 65R15. I also have a set of winter tires of size 215 60R15. I think that means the winter tires are a little wider, with a smaller rim diameter but the same overall diameter. Does this mean I can use the winter tires on the Saturn? If so, do the winter tires need their own rims since the rim size is different?

Thanks for any help!

That tire size should still work fine on the stock 6" wide rims. You could switch them out or use a second set of wheels.

Thanks very much! So the 65 or 60 measurement refers to the rim width and not the diameter?

[Grant@Tirerack]

That number is the aspect ratio. It is the percentage of the tire's width used to figure out the tire's sidewall height. You take 65% of 205 mm and that's about how tall the tire's sidewall will be.
