Has anyone switched out their rims and/or tires that would happen to have a slightly used rear tire they would be willing to part with for a reasonable price? I lost my job back in April and picked up a large screw in my tire a few weeks before that. Needless to say after riding 2000 miles a month up until that point I am anxious to get the bike back on the road. I start a new job tomorrow but need to take of some other past due bills before I spend money on new tires. Any help or advice would be appreciated.
