Over the years I've had a few flat tires while on my motorcycle, and sometimes a road side repair was not possible. And while tires today are better than ever, unless you ride a Ural with its sidecar you won't have a spare tire to put on should your tire go seriously flat. It made me wonder if any tire maker was offering run-flat tires for motorcycles. A friend of mind had such tires on his BMW car, and while they were very expensive they gave him extra peace of mind knowing he would not have to ever be out in the rain on the side of the Interstate trying to change a tire. It would be nice to have them on a bike, especially when far from home in a remote area where you don't even have cell service to call for help.
