I've got some 700x28 gatorskins and think they're pretty great. I did just get a flat a couple of weeks ago from a shard of glass but it has been a while since I've gotten a puncture flat on these tires. Most of the kevlar lined tires you'll want to inspect to make sure if there is any glass/thorns/wire in the tire that you pull it out before it works its way through to the inside of the casing and punctures the tube.

Hey all, thanks for the inputs. I went to my LBS today and all they stock are basically the same tire I got, since I don't really need a new tire yet I'm going to keep riding on these, but going to have them order one of you'lls recommendations; I'm still trying to make a decision.

However, when I was in there the guy showed me a Bontrager tube that was very thick and heavy duty. Anyone ever use this type of tube? It cost about $7.00 and is compatible with 700 x 35 -- 44c.

P.S. Since I opened this thread on 4/3/11 I've had two flats; one flat on the 5th and the second flat today

I would try something lighter than my Marthon Plus tires, but the dang things just won't wear out. I put them on about three years ago and other than topping off the air haven't touched em since. They still have decent tread, too.

I've got 27x1¼" Conti Gatorsksins on the Skinny Bike, and 26x2" CST Squals on the Indestructabike. One flat each, both snakebite pinch-flats caused by underinflation. I no longer go by feel, and use an actual bike tire pressure gauge once a week. I'm 320lbs, and I live in Providence, RI where they seem to use broken beer bottles instead of sand on the streets when it snows.

I have tried the thick heavy duty tubes, and didn't like them in my road bike. They add weight while not adding too much puncture resistance. My daughter's mountain bike has one in the back tire, but she doesn't ride fast so it doesn't impact her. Some local shops in my area have recommended them, but then again some shops recommend Mr. Tuffy liners instead of puncture resistant tires. My son's bike has a set of Mr. Tuffys in his tires, but that is because we can't find any good street tires for his 24" wheels. I won't run the tuffy liners in my road bike tires. I would recommend ordering a good set of tires and using them with lightweight tubes instead of running the heavy duty tubes.

I like GatorSkins on my road bike, and Conti Contacts on my daily commuter.

Could be the thorns from the stickers?

If I was getting minuscule puncture flats, I would probably get some liquid sealant for inside the tubes. I can feel the difference in rolling resistance betwen ordinary brands of road tires; buying completely puncture proof ones must really be a drag, pun intended. The rubber may be thicker or harder and the flat preventative also adds thickness and mass to the tire.

I used to ride a 3 speed with unprotected department store tires in the city of Chicago and it was mostly fine, so I second the suggestion to ensure that you're not underinflating or using too narrow a tire for your rim. I currently find that most any tire which is listed as puncture resistant like Nashbar Primas works fine.
