[MENTION=422519]SloButWide[/MENTION]: Sorry about your dog. That sucks.

Today was a beautiful morning. 64°F, sunny and hardly a breeze. It rained during the night so there were puddles and wet spots, and the air was pretty humid. Lots of people must have agreed with my assessment of the day as the MUP was rather busy for that early in the morning. Lots of walkers, joggers, leisure riders and other commuters.

Got to work and was locking up my bike when I noticed my rear tire on my road bike is starting to show cord. I bought a new set of tires a few months ago anticipating that this set was reaching end of life. I'll replace them both over the weekend. Got more than 3700 miles out of this set of tires, which were the original tires that came with the bike. Not bad.

I did rotate these tires at around 2000 miles. I know Sheldon Browne was an advocate for not doing that, with the idea that you're moving the more worn tire to the front where you need the traction the most. However, I was unable to find replacement tires that matched the original equipment tire, so when I replaced one I wanted to replace them both so they matched. Any of my other bikes I really don't care and will run tires that look different on each wheel, but for some reason I'm a bit more vain with my fancy road bike. So I wanted to try and get the tires to wear out at about the same time so I could replace them at the same time. The new tires are Continental gp4000s which are easy to find, so now I can just replace each individual tire as it wears out and not futz with rotating them. Or maybe I'll try Sheldon's advice and as the rear tire wears out, put the new one on front and move the less worn front tire to the rear.
