Looking to buy some rims soon just wondering if their was any advantage in the width of a rim.
Like does a 15x6.5 have any advantage peformance wise over a 15x7. Or vise versa.

 

A half inch either way isn't going to make a whole lot of difference. Just make sure that the proper tire size for you car is approved for the width of the rims you are buying. For example, on a CRX, the best matching 15" tire size is 195/50-15. That size tire is going to look somewhat stretched onto a 15x7 rim, which is usually the maximum approved rim width, but will look more normal on a 15x6.5 rim.

 

Thats true, thanks
If i ran a 205-50 on a 15x6.5 would that be comprable to a1 5x7 with a 205-50

 

Like I said, a half inch isn't going to make a whole lot of difference, either way.

Most 205/50-15 tires are approved for a rim width of 5.5-7.5 inches. So even there, I would still get a 15x6.5 rim, because it's in the middle of the approved range.
