Summit Racing carries Tornel 7.50-17 bias tires out of Mexico. With shipping they are not cheap. If I kept my bias rear tires an put a pair of radials on the front would it be so bad? I remember having bias in the back and radials on the front of my very first car 25 years ago and being told it was bad. But not noticing any problems. I was 17 then so nothing phased me. Haven't had a bias tire since.
