I just noticed the "wear bars" on my rear Avons.(25K kms) Last time I got a quote from Zdeno, and then went to BKBike on hwy 6 and they matched the price. Where do you all, from this area, buy your tires? Do you order them from the US? Unfortunately, I must go to a garage for the install, and that is a hun for the rear! So I'm trying to save a little do-re-mi. Thanks for your help.
