I guess it all depends on your definition of dirt and/or gravel roads... Right now, most of the dirt roads here in the DC area are pretty smooth. Come spring, they're going to get re-graveled and then riding on em on road tires won't be all that fun. :nah

Me? I'm on some 28c Gatorskins at the smallest and more usually on some 34c Racing Ralphs. I AM on cross bike(s) when I'm riding these tho, that may make a difference. Buddy of mine has Michelin Jets. They seem to roll faster than my RR-s.

I *should* be out riding dirt roads for 4hrs today, but its about 20deg F out and the wind is howling. The couch monster and its evil minions 'the Screw-its' are attacking.

They've already been mentioned, but Tufo C Elite Ride 25's. The tubular-clincher model. You can load them with sealant (they work better than clinchers for this since there's no tube) for thorns/glass, and they are as resistant to pinch-flatting as any tubular, perhaps more so because of the lack of a tube. The result is you can run them at way lower pressure than any clincher, meaning a better ride and better traction on dirt and gravel.

I use these for training, my team (we all race road and cx) often take dirt/gravel roads on our training rides. I can absolutely crush on these because of the 25mm size and the lower pressure. I often run them at 50-60psi, try that on a clincher on a dirt/gravel road and you'll pinch at any kind of speed.

My point being, the advantages of running lower pressure more than make up for the lack of a supple casing, and the extra grams. They're not cheap, hard to find for under $79 per tire, but I find the on/off road performance for my riding to be worth it.

Hi,



That sounds contradictory to me.
You can have lower pressure, more supple casing hence lower crr and less weight in a single tyre.

Ciao,
