A bike mechanic looked at my 97 wing's tires. After explaining to him that the front tire is SUPPOSED to be mounted backwards, he noticed that my Michelin tire in front is a bias-ply and the rear on my Roadsmith are radial. He says you shouldn't mix the two. I've had that tire on for quite a while without any problems but it is coming near the end of it's lifespan and will need to be replaced soon. Does anyone have any opinions about mixing the two kind of tires? Do they even make a radial tire I can use on the front?
