Summer Tyre

Ultremo ZX (25mm) for me for the last couple of years. Winter tyre has been the Durano which is marginally slower. The ZX is a much better tyre than I need for my purposes, but after getting a deal on some a while back, one that I instantly loved.

The only puncture I've had in the last 4000 miles (on the bike using these tyres) was on an old Ultremo R1 which had done 1500 miles by that time.

I swear by Schwalbe even more so than I did Michelin in the 80s and 90s... I just can't get on with Continental for some reason...and I have tried!

my schwalbe ultremo ZX's have been awesome these past 4/5 months! much, much quicker than any others!

I use Open Paves for winter and Open Corsa SC for the summer.
Buy on performance, not puncture resistance (it's a fallacy to sell crappy poor performing tyres that are just super heavy)
I've had one flat in the last 2 years of riding on just vittoria tyres.
(I get a 'season' out of each set, so one set of paves in a winter, a set of corsas in a summer)

You want all the properties of your current tyre... but faster? Don't want much, do ya

Have you considered the Corsa CX?

If you want speed and puncture resistance, go tubeless.
E.g. Schwalbe One...

Stick with the Pave.

There aren't many faster tyres and you will sacrifice puncture resistance with any of them as they're all race tyres so lack the punture resistance. Probably the most durable alternative is going to be the Continent GP4000S.
