This is what's left of my rear tire. It looked a bit worn when I got the bike with 1150 miles on it. It's already done for. I have a replacement on order, and I'll get the oil changed then as well. I hope the reason the tire wore out so quickly was because the previous owner did a long burn-out on it. I hate the idea of spending $160 on a new tire every 2500 miles or so.
