Have you heard of any instance that a bicycle tire damaged a rim?
Can you furnish specifics of the occason and describe the damage?
Since Nov 2001 I use the polyurethane/nylon microfoam tire that has no air tube. wwww.airfreetires.com Others who read my posts have asked at their local bicycle shop about airfree tires. They were told vaguely "they damage the rims".
In the nine months and 2000+ miles that I have ridden bicycles equipped with airfree tires I have not noted any damage to the rims.
Will my rims suddenly shatter? or perhaps crumble on a downhill whizzzzzz at 48mph to pitch me headlong into a cactus; or to die impaled on a highway reflector standard gurgling in agony for the amusement of fourteen tourists who stopped to photograph this once-in-a-lifetime visual treat?
