Road Cyclists: what tyres are you using?

25 mm Schwalbe One on the nice bike, 23mm Durano Plus on the less nice bike.  Neither have punctured in many hundreds of miles and both roll very well.  The 23mm Duranos are surprisingly comfortable compared to the 25mm Ones.

Michelin Krylion (folding) absolutely bullet proof.

GP4000S, used them for years and felt no need for anything else. They last me ages and I've had 1-2 punctures in all the years I've used them.
