Reply to "Tires for OEM 15 inch wheels"

Not that I'm aware of, Rene. Pirelli occasionally makes a close analogue size 275-55x 15" P-7R, speed-rated street tire that properly fits an 8" Campy, or with a little stretching, a 10" Campy. And in spite of whats on the Internet, I'm told by a Pireli rep' that Pirelli's 'R' designation does NOT mean 'race' but instead means 'rally', as the P-7R's internal construction added extra belts just underneath the tread area. This was to restrict tire growth at speed, so precision rally speedometer/odometers would register more accurate speeds and distances.

4X4 or light-truck tires tend to have stiff sidewalls suited for carrying heavy loads. They also tend NOT to be made with sticky compounds, so their handling and ride performance is... truck-like. They are also not high-speed-rated. I suspect your local yearly registration inspectors will reject them for use on a high-speed sports-GT, but it's been many years since I visited France so things may have changed.
