Our rough roads have eaten every tire I have tried (Michelin, Panaracer, including previous Continentals and a list of others). These were on sale and decided to give them a try, they are holding up better than expected with the use of kevlar liners and puncture resistant tubes-I spend time riding not repairing. I have been very impressed with the road feel of these tires and after a long ride I usually have slight cuts in the outer tire casing and so far no cuts.
Have ridden on this tire for 18 months in 28 width. Have always ridden 23 to 25 but after doing some more research decided to try the 28's. As with many things in life it's hard to admit that everything you thought you knew was right is proven wrong when you finally give in and try. These tires are not slower, they might be a little heavier but not enough to make a difference for most riders. Their toughness is amazing. I finally decided after a summer of riding to buy another set in preparation for spring. The current set has multiple slices that would have flattened other tires.
I had previously ridden on Vittoria Open Corsa clinchers. These ride as fast as the Vit's but not as supple. The Vit's are good for a 1500 miles max. and seem to cut very easily.The speed advantage the Conti's provide more than makes up for the less supple ride quality and so far I've experienced no punctures. When on sale I usually buy a pair.
Super fast, super grippy, relatively long lasting. These have been my go-to tire for as long as I can remember. New bikes get them installed near immediately. I use these daily and no complaints on longevity, but the 4-Season isn't a bad option if you're not racing.
Nice tire except the sidewall failed (tear) after only 1200 miles. No obvious cause - smooth road. Too bad - I liked it otherwise. Seems like it had goodlow rolling resistance on my kind of roads. Won't buy it again because of the failure.
I decided to switch over to the 4000S after reading all the positive reviews for a summer of riding in the Mountains of Western North Carolina. The tires felt fast and smooth... very nice riding. Unfortunately, after a few hundred mikes I had a sidewall blowout (very dangerous on mountian rides!). I purchased another 4000S from a local LBS, only to have a 2nd sidewall blowout about 7 weeks later. After my first blowout, I started regularly checking my tires for cuts prior to rides and saw nothing. Talking to 2 members of my cycling group they also experienced sidewall blowouts before on these tires. Maybe just bad luck, but based on personal experience and comments form others I will not use these tires again. I have been riding Michelin and Specialized tires (both prior and after) on the same wheels without incident...
I have tried many tire brands over the years but in the end I always come back to the 4000 S. Rolls great and is far more puncture resistant than almost anything else I have tried except perhaps for Conti's Gatorskins
