thorn resistence tubes, kevlar tires?(7 posts)

thorn resistence tubes, kevlar tires?Frictionless
Oct 18, 2003 8:26 AM
Hey all,

Does anyone have experience with thorn resistent tubes? I saw these on performance for $6, just wondering if its worth it.

Or is it better to drop the cash into kevlar (or other) tires? Is there any consensus on the 'toughest' road tires?

I used to use Slime Liner tire linersKen of Fresno

which worked pretty well. Much lighter than tp tubes and every bit as puncture resistant. A bit of a pain to install though. Every once in a while I would get a flat on the portion of tread near the sidewall where the liner didn't cover. After I discovered Michelin Axial Carbon tires I completely quit using the liners. The Carbon tires seem to be extremely puncture resistant and only 260 grams. I've had only l flat in over 2,000 miles, and this area is notorious for flats due to thorns and random road debris. I'm sure there are tougher tires out there, but for the feel of the Carbons it's been a perfect tradeoff.

Best of luck,

Also, as far as Slime goes, this stuff doesn't seal high pressure leaks.
Now, as far as Kevlar goes, yeah, it's good stuff.....if the THREAD COUNT is high. A lot of cheap tires use 50-6- tpi kevlar, which does next to nothing to prevent punctures. Yeah, the kevlar doesn't break, but the glass/thirn/etc. just goes between the threads!
The toughest road tires are Specialized Armadillo and Nimbus, and Tufo S33 specials.

I've used Specialized Armadillo for hundreds of miles with no flats. I only use them for training rides, they are heavier than my Conti 2000, but NO FLATS! I'm sure there are others out there that are lighter and work as well, I'm sold on Kevlar myself.

oops, forgot to mention I also have those thorn resistant tubes........way to heavy the tires are the best way to go IMHO.
I think you are confusing Slime Liners with Slime SealantKen of Fresno

Specialized Airlock tubes use a different kind of sealer than slime does, and I've been very happy with them. I once pulled a tube out and when I looked at it I could count seven holes it had had sealed.

If you want protection against thorns, goatheads, and things like that, special tubes and kevlar in either the tire or in a liner like Mr. Tuffy's do work - but you'll pay the weight penalty. For things like hard hits on glass or nails kevlar tires or liners help more than self sealing tubes. Nothing is totally protective, you need to evaluate the threats on your rides and customize your protection.
