Just for gee-whiz I searched the net for motorcycle failures with car tires........................could not find a one, but I sure found lots of failures with motorcycle tires, I mean serious failures with fatal injuries, totaled bikes and multiple law suits. Kinda scary reading about all those failures, many low mileage tires, many with experienced riders who check tire pressure all the time and even the morning of the day of the failure. I'm not for or against any kind of tire, I believe we are all free to do what we want with our bikes, it's your call.
