I had a tube blow out today on my ride, and while checking the tires on my roadie I noticed some serious wear on my front wheel. I have replaced the back tire a few times over the years due to damage (something took a bite out of my Gatorskin last fall). But, the front one has been on there for years.

Anyway, it's time to get some new rubber on the front, and I figure I'll get matching rubber for the back.

What do you look for in a tire? Anything in particular?
