Hello, Im wondering if inset adds to the width of the rim. I’ve got some 18×9.5 +15 inset rims that I thought would fit on my car, however they are too wide. I measure the width and it comes out to 10.5 inches. I’m going to buy new rims, and want to make sure they fit properly this time, so I’m wondering if it’s the inset that is causing them to be an extra inch wide. I see tons of people running 18×9.5 rims on my car with no issues which is what confused me. Thanks for any help.
