Have a look at
this comparison which compares Gatorskins with GP 4 Seasons and Schwalbe Durano, and play with other tyres that have been tested. I currently have a Michelin Pro4 SC on the rear.
The
Gatorskin full review, inter alia, says: "When looking at the Continental road bike tires line-up, I noticed the new Grand Prix 4-Season. This seems to be a tire with the same properties as the Gatorskin but is a new design with the latest tire technology. The 4-Season seems to be close to a GP4000S with an extra layer of Vectran breaker and a DuraSkin sidewall. I'm looking forward to comparing this tire to the Gatorskin (edit:
Gatorskin Vs GP 4-Season ) as it will be a good example of how much tire tech has progressed in the last ten years."
Taking the first comment on that review (referring back to the thread title/topic):
'Russ' says: "I take issue with gatorskins having a compound optimised for cold weather grip - I find them treacherous in the cold and wet and have come off several times with the scars to prove it. Just googling, gives similar experiences from others. Gatorskins have a single compound, hard carbon rubber for durability but this leads to poor grip in the cold and wet. For cold and wet conditions, high hysteresis silica compounds with appropriate transition temperature give much better traction than carbon rubber and are just as durable. Gatorskins are a cheap carbon rubber tyre - this is old technology, cheap to manufacture with high profit margin, and Continental push them for good reason."
