Wow, glad you're okay.

Was your wheel damaged, or did it get out of true? Or did they have to order a tire for you?

Not everyone recommends rotating tires. If you do decide to do that, ONLY rotate the front tire to the rear, NEVER rotate the rear tire to the front. That's because the front tire is so critical for control. The reason some people like to rotate their front tire to the rear has nothing to do with tires wearing differently - it's so they'll never have a worn tire in front.

The rear tire always wears quicker because it's the drive wheel. If you don't rotate tires, you'll find that you'll get anywhere from half again to twice as many miles out of a front tire as a rear. It's easier to track mileage on a tire if you don't rotate them, obviously. If a tire doesn't have wear indicators, it can be hard to tell how much tread is left without taking it off the wheel. I'll usually get 3000-3500 out of a front, 1500-2500 from a rear tire.
