I got through several 700Cx25 UltraGatorSkins last year and had quite a
lot of trouble with them. They are reasonably fast for a supposedly
tough tyre, but I found their puncture rate was terrible. On average I
got only slightly over 200km between each puncture. Occasionally I
would get over 1,000km without a flat, then I would get a whole string
of them to bring the average back down. None of the UltraGatorSkins I
discarded was close to wearing right down. One of them only had about
400km on it when I had to throw it away because a deep cut in the tread
caused it to bulge so it was out of round.
I also found that as they wear they get a chewed-up appearance, then
they start puncturing spontaneously. What seems to happen is that the
casing fails under the tread, the tube starts to poke through, a flap
of tread lifts, and bang! Many of my punctures seemed to be similar but
less spectacuar tyre failures rather than penetration by a sharp
object. There would not be a bang, but a sudden loud sound of air
escaping. The tyre would go down rapidly until it was faily soft, then
the leak would almost stop. With this kind of puncture I would usually
find a little hole in the tyre but no foreign body stuck in it.
The strange thing is that comparing notes with other UK cyclists it
seems UGS users fall into two camps. Some people seem to go thousands
of miles with absolutely no trouble, with the tyres wearing down and
retaining a smooth appearance, while others find as I do that the tread
develops a rough look and the tyres puncture frequently. Some Audax
riders have started referring to them as UltraHamsterSkins.
