Review on Goodyear Folding Mountain 2 125 Black Sports & Fitness by Angel Serafini

Just installed on my mountain bike so far so good. My rim is 584 x 21, they were a bit narrower than the previous tires (2.25). They fit, but need a bit more finesse to attach the bead to the rim. It took a while for the first tire, but for the second it was as easy as peeling a pear. I had to pump a little more air into the inner chamber, and while I used my right hand to press the tire bead against the rim, I used my left hand to press the chamber from below. This will help keep the beads in place. After I was done, I took a hot spin around the neighborhood and started carrying the mail!
