It's time to replace my stock tires on my Trek 2.3. Any suggestions on which ones to purchase or consider? I'm on 700 x 23's now and will replace with same size.

Thanks

Frankie, at the moment, I'm running tubless. But when I go tubed, I still stick with the GP4000s (see this thread for my opinion on them and some others' suggestions: http://www.twospoke.com/forum/f30/looking-new-road-tires-937/). I've never had a single problem with those tires.

Not a bad recommendation from Xela, but I think you should try out the Vittoria Open Corsa EVO CX in 25mm. I'll be you the first ride you'll be blown away.

Weav, you're absolutely right about the ride quality. My only complaint when I ran those was I would only get about 1200 to 1500 miles out of a set. What kind of mileage did you see?

[Weav]

I tend to not be too hard on tires so I get a little more than that but you are correct that they have a reputation of not lasting as long as some do. But the ride quality is the trade-off. I've since switched to tubeless like you. If money isn't that big an issue I say get the Vittoria's, but if money is tight then go with the Conti 4000S, don't know if they have a 25mm version or not, but the 23mm version is a nice tire and since that is what the OP said he wants that may be the way to go. Unless I can talk him into a 25mm.

Continental Grand Prix 4000s....
Are these a tube tire? I saw them on a website and they called them clinchers, wasn't sure if that was a tube or tubeless.
Saw them for $63, but still looking for a better deal.

[Weav]

Yes they are a tube tire. Anytime you see the words "clincher" they are speaking of tubes. The two other types of tires/wheels are called "tubular" and "tubeless". Tubular tires need to be glued onto the rim of a tubular wheel. Tubeless is the same type of tire as your car tires. They seat themselves onto the rim when inflated without the need for a tube. They allow you to run lower tire pressures for more comfort and less rolling resistance, because you don't have to worry about pinch flats like you do with clinchers.

I can see lower tire pressure giving you a more comfortable ride , but I would think more pressure would give you less rolling resistance. as the tire does not flaten out as much with more pressure. less contact aera less resistance ???

Pretty good article that should give you a decent visual on what's going on with pressure/rolling resistance/coefficients/give & takes..... etc etc etc.

Thanks for the suggestions, I now have a direction to look toward. I knew could get the help I needed here, thanks again.
