Hello I was wondering if I can use winter tires 195/55r16 on a 16x7 rim? Or can I use another 195/ which fit better ?
The only 2 concerns about fitting a tire to a wheel are the diameter (they must be a perfect match), and the width (there's a range of widths that will fit).
In your case, you are fitting a 16" tire into a 16" wheel, so we only need to look at the width. According to , 195 is the minimum width you can fit safely on a 7" wide wheel. Any 195 width tire will fit the same, changing the aspect ratio will only mess-up your speedometer and odometer.
Is 195/55R16 your OEM tire size?
