Question: what's the max psi?
Document: tires are great, did a century 2 weeks ago and doing another one this weekend.
almost a year and over 2000 mi on these tires without a single flat, though I do use Mr. Tuffy liners too. A bit skittery in high speed turns but plenty of grip otherwise. Though they ride somewhat rougher than the full race tires they are extremely tough and cut resistant and long wearing as the tread still looks new. The narrowness of the tire is perfect for older frames with little chain stay clearance.
Was riding with continental 4000S tires which are great tries except for the fact the rubber is soft and all the crap on the road ends up in the tires; flatted twice in one ride. Since switching to gatorskin tires, no flats and the tires seem to remain debris free. I ride 100 to 200 miles a week and simply don't have time to be changing flats every ride.This is an update on my review.
Theses tires really are tough while not being slow. I mistakenly bought the non-ultra last time and I got a flat in two weeks. I work on a construction site and was riding my road bike around a little bit so....Anyway the armadillo tires I love also but they aren't as fast. These tires have totally upgraded my city bike riding experience; I must ride over 50 glass piles a day and I never had one flat with these tires.
Review downgraded to one star.
PROS"No flats so far"- 4,000 miles...without added sealants. Tread still seems okFor exercise/leisure rides I will take "no flats" over "performance" any day.CONS"Slippery" I love to corner super fast- but with these tires I cannot/will not corner/lean as hard or fast.
My Gator Skin lasted 2 miles before the sidewall blew out. Do not buy these tires, they are not worth the money spent. I put my old Bontrager hard case race lite tire back on and will never buy anything but Bontragers in the future.
Most of my flats and wear are on the back tire so I have been using the Gatorskins on the rear wheel and a faster (less flat resistant) tire on the front. So far this has been working out well and the number of tires I replace a year has gone down. The Gatorskin tire does a decent job of standing up to the lousy road conditions in the New York City area.
Just today 20 miles from home the sidewall of my front tire blew out and flatted. There was no evidence of anything puncturing the tire, it looks like it just blew out from the inside. This left me stranded as my replacement tube also blew out when I inflated it because the sidewall was compromised. I run these tires as all my tires at 100psi so there was no overinflating, no foreign object puncture, it just blew out !!
I bought these for my husband and he loves them! They ride smoothly and give him a feeling of security that he won't be dealing with a flat tire in the near future!
Answer: no
