I took my rear tire into A respected dealer here in Denver to put on a new tire. This is the new Fay Myers store on Arapahoe for you CO boys. First, I usually go to Steele's Cycle for new tires. They put them on for free if you buy it there (good prices too). But it was late on Saturday and I don't have much time any other day before my trip to Crested Butte in Sept. So I went to FM. I asked for a Dunlop 756, they didn't have it. I asked for a Dunlop 739, they didn't have it. So I said what do your have, they said IRC. OK, fine. I've used them before, they are good tires. Well the service guy took forever to get to it after telling my he'd do it right away. Then when I get home, the tire is on backwards, the arrow points to the rear instead of the front. At first I thought, no biggie. But then I noticed the tread angles. Flat on one side (the correct side) and angled on the other (the wrong side). so now I have to take it back. I wish I didn't despise putting tires on myself. I won't do it unless it is absolutely necessary, like on a trail with a flat. But come on, a respected dealer screwing up like that? Now I have to ask my wife to drop it off and pick it up because I don't have the time to do it myself. One positive, sort of. As I was taking off the tire again, I noticed I have a pretty good bent rotor and it was hanging up on the inside pad. Good to find out now than on the trails.
