Bob, you do not need new studs.

I think you were asking if I were pleased. The short answer is yes.

The longer answer is that I did notice some improvement in ride quality due to the lower pressure, but the most significant change I noticed was that I no longer felt like I was rolling over the outside tire in a fast sweeping turn on the interstate. We were living in West Virginia at the time, and some of their major highways had pretty good bends in them. I would suck up the seatcover when I hit them anywhere close to the speed limit. I no longer had that "feeling" when I converted.

The tires also run much much cooler in the summer than the 315s did.
