I've seen a member here put his stock tires back on new rims.
Personally, I don't see the benefit. If you are going to drop some coin for a nice wheel, you should get a nice tire too.
All too often tires are overlooked, but they are a large factor, if not the most important factor, in the noise, ride, and performance of your vehicle.
Plus the unmounting and remounting of tires is a waste of effort (whether someone else's or not)
How much treadlife is left on the current tires?
