Having had yet another p******* this morning I am going to change the 4 season for either conti gatorskin hardshell or schwalbe durano+....which is the best? I presume that the folding version is much easier to remove from the wheel than the wire version...is that correct?

The 4 seasons are better than gatorskins.

Think you've been unlucky, or is it worn ?

I've not noticed much difffence in the ease of fitting/removing between folding and non-folding tyres to be honest.

I had problems with the 4 Seasons, they need a lot of maintenance. You get very few immediate punctures but you do get flints slowly working their way through. I run normal Duranos on Lelly (touching wood!!!) without a puncture in 1300 miles (that's probably screwed my weekend of cycling!). Never had gatorskins so can't help there.

I have no faith in the 4 seasons, picked a nice piece of glass out of the tyre this morning...the cycle path between Bristol and Bath is a minefield (or should that be glassfield!) and I need a strong but good rolling tyre (the swhwalbe marathon looks a bit of an animal :smile:)what about specialized armadillo? It's a shame because the 4 seasons are not cheap...

That's why I got rid of 4 Seasons. If an £11 tyre punctures you just think "B****r got a puncture", if a 4 Seasons punctures you think "Hang on I spend £30+ on these". You need to check the 4 seasons after every ride and clear the flints. If you do that they aren't too bad but I found it a faff.

I've got 25s Marathons (not pluses) on my commuter and so far I quite like them. I set my second fastest time to work this morning although I do think I'm putting more effort in than on my old 23s Rubinos. However as far as I know Marathons are a "fit and forget" tyre to a large extent. They definitely take more effort away from lights etc due to the weight.

It would have made little difference if I had checked my tyres this morning the puncture was caused by a small and sharp piece of glass and the 4 seasons appeared unable to stop it piercing the inner tube (at least I found it easily and removed)...but then of course no road tyre might have been able to stop this type of puncture.

If I were cycling on a cycle path that is a "glassfield" then I would use marathon plus tyres despite the fact I dislike them because they seem to be the best at coping on such glass laden surfaces.
 
if you pick up a piece of glass, your tyre will go down - regardless of how much you spent on it.

Not necessarily. Some tyres manage to force the piece of glass back out, others allow them to work through. Now nails, nails are different.
So you've never run over glass and it hasn't stuck in the tyre? Or even had a puncture were the offending article has been expelled from the tyre?

Ladies and gentlemen, I give you one unlucky (and I imagine nervous around glass) cyclist!

Excuse my ignorance but I presume the difference between the wire and folding tyres is that the folders are meant to be easier to remove...I found this with the Grand Prix 4 season ...they were easier to remove wheras gatorskin which i have on my 2nd bike are a bit of a pig...therefore I presume I should go for the folding version? is that right?
