Yesterday I did a 50 mile group ride from Urbana to Monticello and back. It was the first ride of this distance & intensity I have done in months, and it gave me a pretty good idea exactly how out of shape I am.
As we were just coming back into town I got a flat tire. Some other riders stopped to help me change it and we quickly realized that my rear tire had outlasted its usefulness by a number of miles. In many places the tread had completely worn through and the purple liner was visible.
I suppose that's what happens with cheap tires. I got this tire in a pinch at a bike store in Peoria after discovering my rear Brontrager Race Lite had been sliced up somehow in the trunk of my old car. I still had a Race Lite tire in front and it has lasted over 5000 miles.
Needless to say it was time for new tires. Fortunately, Champaign Cycle was not too far away, so I decided to save myself a trip later in the day and just go straight to the bike shop on my way home. I picked up a pair of Bontrager Race Lite Hardcase tires, which have been highly recommended by multiple people.
