The Continental Grand Prix 4000S Folding Tire boasts global appeal as the best all round race bike tyre on the market. Not only is it fast and super grippy, thanks to its state of the art Black Chili rubber compound, but it is also tough with a healthy tr
Weaknesses: Dead feeling, sluggish and heavy for climbing.
I'm not sure why everyone raves so much about these tires. They do wear well, but at the same time, they have kind of a dead feel them. A wooden feel is the best way to describe it. The best trait I've found of these tires is that they're confidence inspiring on steep descents. On the flip-side, I find them to be slow on steeper hill climbs. Maybe it was because I was running the larger 25mm version. In contrast, Vittoria Rubino Pro's (25mm) feel better and are faster on the hills, and are less expensive.

Strengths: Highest mileage tire I have used in a long time- good traction and suppleness. I have not seen any of the sidewall issues that others are talking about.
Weaknesses: Conti just quit making them- I'll bet the new GP 4000S 2 tires are not as durable...
On the balance the best high mileage tire I have ridden- better than Vredistein TriComps, better than Vittoria Rubino Pro's.
If someone ran a deal on these I'd scoop up a couple of pairs.
BTW high mileage is over 4000 miles on the rear one. I weigh 162 lbs and run 25's at around 100-110 psi. No issues whatsoever.

Strengths: Very durable, light, dependable until worn down, rolling resistance noticeably better than other tires. Easy on, easy off the rim.
Weaknesses: I have not had the sidewall problems I see mentioned, but the sidewall does tend to thread off. That is to say that the sidewall after many miles and about 50% wear starts unraveling, the threads can come off and wrap around the axle.
Overall I have been very happy with these tires. I have given away old tires to friends who ride on them for years, (they don't ride the kind of miles or intensity that I do). I rotate my tires roughly every 500 miles when I clean my bike and I can get 2500 to 3000 miles out of a set, I ride hard and fast on some questionable roads in Southern California.
Weaknesses: Fatal sidewall cut at 250 miles...it seems I'm not the only one to have this problem either.
Although I am mostly happy with the ride of the 4000s...I have to be honest and say I've found a better ride with a different brand. Compared to others, the 4000s is a bit harder but not to an extreme level.
My only complaint is getting a fatal sidewall cut on a relatively brand new tire. $50 down the drain. Looking this up, it seems this is a total "hit or miss" issue with this tire. The bad part is there seems to be plenty of "hits" when you do an internet search for "conti GP 4000s sidewall cut".
Figuring I've found a better ride with a different brand and they have lasted me all summer and 1000+ miles without a flat, I probably won't be buying another set of these anytime soon.

Strengths: Great traction, snappy acceleration, good road feel, long wearing, secure feeling in corners, decent ride.
Weaknesses: None that I can think of. They can be expensive to buy, but the performance and mileage you get from them, in my opinion, makes the price worth it.
My tires are the 700x23s. I finally replaced the rear tire, with another GP 4000 after more than 3700 miles as the wear indicators got difficult to find. The front still looks like new.(The mold mark is still visible down the center) I got a small cut in the rear at about a thousand miles that you could see the anti puncture belt through and thought I was screwed but it never proved to be a problem. I always felt secure in the tight curves, these tires grip the pavement very well. I actually hit 50.95 MPH the other day on a steep twisty section and was very comfortable all the way down. Some other reviews I have read indicate that others have had poor luck with these tires flatting etc., but I learned very early in my road riding experience if I made sure my tires were properly inflated before "every" ride I almost eliminated problems with flatting, and I ride some very nasty Pennsylvania rural roads. I have only had 1 flat about 5000 miles ago,(a tiny sliver of metal) and it wasn't on this bike or a GP 4000. I'm sure there are clinchers out there better suited for pure racing, but, a performance oriented recreational rider like myself may find this tire a perfect combination of long wear and high performance. Personally, I'm sold on these tires and will buy them again for both of my road bikes. These tires have been so good to me I don't think I want to take a chance with others.
