I value my life way to much to be riding on a tire like that, yeah I wear a helmet to. Last year I went on the Ramapo 500 which is a 500 mile weekend run and there was an idiot on a c14 with a tire that closely resembles the one you posted and he even had a passenger. Incredible, even if you don't care abt yourself, if you have a blowout you will most likely wreck the bike!!
