okay so I didn't really pay much attention to the speal they gave me when I bought my bike and the extended tire warrenty, but I thought it was good for when the tire wears out. I asked the service manager at bob schultz how much wear the tires have to have before I could get them replaced. he said that the extended tire warrenty was only good for damaged tires, not worn tires. anyone out there had any experience with this? is it true that the tire has to be damaged for the extended tire warrenty?
