The avon has a hard center and soft edges. The soft edge just ground away the center and other edge looked new. I dont know enough about the shaft drive to know if it can be put together so the tire is "off camber" or cockeyed.
The honda shop in texarkana did the exedra. Never told me they hadnt balanced it because it was too big for their balancer until i noticed the rim had all the tire weights removed.
I put the rideon tire sealant in and am pleased with it. Thevtire is wearing perfectly. No vibrations. No need to add air every couple of weeks.
