Update: Both pairs of tires have been claimed.

I have 2 pairs of cheapish Kenda 37x590 tires. Aka 650A or 26 x 1 3/8" for your old 3-speed. One pair looks brand new and never mounted, the other is virtually new but looks like they were probably mounted and ridden long enough to wear off the rubber molding nibs.

You pay shipping, would prefer one pair per customer if more than one person responds.
