Kevlar tires

Are kevlar tires worth the extra money?

Yes. I've had them on my road bike since 2003 and average a flat every 1500-2000 miles. I also had them (different brand) on my commuter bike (when I was a bike commuter) and averaged a flat every 1500 miles.

I started commuting using regular road tires. I had flats sometimes twice a week. Mind you, it's NYC, streets are dirty. Then I used Specialized Armadillos and I got like 3 flats a year. Then I used Maxxis Re-Fuse and I got zero flats in two years. They're heavier and have higher rolling resistance but for city riding, club rides and anything non-competitive you can't beat Kevlar tires. Some tires like the mentioned Armadillos and Re-Fuse have more than just a Kevlar layer (belt) they use some proprietary compounds or nylon jackets to add another layer of protection.

Kevlar for flat protection or Kevlar beads? The former can yield fewer flats, though the best way to not get flats is to stay away from the areas of the road where flat-causing junk collects. Do you currently have any issues with flats? The latter simply yields lighter tires. Whether it's worth it to you or not depends on what your tolerance for spending money on bike tires is.

There is a downside to Kevlar reinforced tires, they can slow you down, but that is only an issue if speed is important to you.

Kevlar beads are nice if you need a spare, they take up a lot less space. Otherwise, it doesn't matter all too much, the weight savings (for me) are pretty marginal

Kevlar liners are nice if you get a lot of flats.

There is no other answer than YES. I have taken my kevlar Infinities, Race Lights and others through all sorts of crap. It's extremely rare that I get any kind of flat, even a slow leak. In fact, it didn't happen once the ENTIRE tour. (1600 miles) I don't waste money on anything else really.

The belts minimize flats and don't contribute much to rolling resistance.
