View Full Version : Slime or Kevlar?

01-06-2012, 12:42 PM
I'm looking for an intermediate anti-flat fix before getting new tires. I've got about 2K miles on my Panaracer T-Servs and I don't plan on changing them before 4K miles or so (what can I say, I'm cheap, just ask my kids). But...this time of year seems to give me more flats (really sharp salt crystals on the road? I dunno) and I'd like to have some protection. I just replaced a tube that had been injected with green slime (I'm sure there's a better technical term) which made my tire into a run-flat marvel (until a catastrophic tube tear) and I've heard others suggest a Kevlar liner, but I don't know which would be better.

Mind you, my next tire stop will be Armadillos (if they make them 700x35C) and, at least accordingly to other threads, my problems will be solved.

I think you'll need the Infinity or Nimbus flavor of the armadillo to get a tire size that wide.

I've used Stan's (http://stanstiresealant.com/) sealant for a while. I honestly can't attest to its effectiveness, though. I haven't had a flat that I can remember in over a year. I usually remember those things.

I've had good luck with the Nimbus in 35 so far. Zero flats. I did have a manufacturing deflect in one, and I had to limp home with a bulge in the tire, but it didn't go flat, and Specialized customer service replaced it with no charge or delay.

I would avoid Slime like the plague, it DOES clog up leaks, but you'll be riding on a 10-20 psi tire.

I have a slime tube - no flat yet, but the slime clogs up the valve, making it hard to open. Had to use pliers once.
