Tonite was the second time this year I had a rear tire that was low on air and/or flat that I drove on for at least a few miles. This time I made it to a gas-station before it got all the way down but I think I knocked it off the bead cause the tread is CONCAVE . Also it's got a pretty fierce wobble thatgot progressively worse on the ride home. fukkin stockers will be on till spring now...... (unless the tire isn't as bad as I think)
