Dave, what about the avon? You said you had one and tossed it because f a flat and got another in a different size, right? So give it a chance and see how far it goes. I only have 500 miles on mine so i can't even begin to access it's longevity, but the fact it's dual compound and the tread is deeper should prove to give far greater mileage than the metz i would think. See how that works out B4 chancing a car tire's safety. When i was young i dropped many bikes due to the fact that tires for bikes back then were hard rubber like car tires. Today i can ride far past the limits i could back then because of the compounds bike tires use today. I would stay away from CT's. It's just not safe regardless of what anyone says.
