Re: Tire or rim problem?? I need suggestions
I had this same problem. Never encountered it until I got a shift kit, as well. My tires were also technically larger than the 2.125 tubes that were in them. The way I solved it was to use a larger tube. My tires are 2.2 and the tubes in them now are 2.35, inflated to 75psi. My rear tire also has a 2nd tire inside. No problems since.
