It is no wonder why the Grand Prix 4000 S is not only Continental's best selling tire, but the best selling high performance clincher in the world. Literally.
It has everything you demand from a tire - rolls fast, very puncture resistant, excellent grip, will not tear or slice and seemingly lasts forever. The firm-ish sidewalls do not flex much, so they never pinch tubes due to flex. Now, take all of those attributes and add the fact that they are very light (205 grams for a 700x23mm) and easy to mount and you have a winner by anyone's standards. It is hard to have a conversation about this product without using words like, benchmark and industry standard.
The magic starts with the Black Chili compound. It is derived directly from Moto GP racing and offers lots of high end technology. It is essentially a blend of natural and synthetic rubbers. The natural rubber is mixed with 'nano' sized soot particles, who's surface properties are optimized to deform around surface objects and inconsistencies in the road for better grip. These small particles also form a tighter bond with each other improving compound strength for improved longevity and shear strength. Thanks to these polymers and carbon fillers, the Black Chili ends up being some of the strongest and most durable tread available as well as having the least amount of rolling resistance. The fillers also greatly reduce flatting.
Under the tread, Conti has placed a strip of Vectran which adds to the already out standing puncture resistance. It is essentially a protective belt made of super strong and extremely lightweight and pliant material. Small wear levels indicators have been molded into the tread to measure wear.
The casing is 3 plys of 330tpi material which is flexible enough to give compliant road feel, but stiff enough so it will not flex in corners or under load. This also reduces the chance of pinch flats when run at proper tire pressure.
While designed primarily as a race tire, we have found most riders will use it year round due to the superb durability and extended mileage the 4000 S offers.
I ride a lot of country roads with pretty poor pavement. I used to use Michelins, but kept getting a lot of flats. Since switching to Continentals (4000GP) I rarely get a flat, the tires are very comfortable and have a good grip. I have almost 4000 miles on the front tire, but the rear ones usually only last about 2000. I inflate to 110. I strongly recommend these tires to anyone even though they are a little pricey, the value is there and I feel very safe with them.
Pros: durable, great handling
These are the second tires I have had on my road bike. Compared to the tires (Mavic Aksion) that came with my Caad10 3 they are far superior. These tires stop markedly faster and hold the road like glue.
Pros: Excellent traction
Cons: None so far
Ditto previous comments about this being the best all-around road cycling tire out there. I have 4,925 miles on the rear tire (put on new) and the wear indicators are still showing (barely...the tire will be retired soon). I'll get 5,000 mi on this rear tire. Front now has 3,909 mi with PLENTY of wear left per the indicators. I weigh 172 lbs and ride on rural, well-paved SE Iowa roads. Oh, yeah, no flats on either tire yet. A little bulge on the rear tire sidewall from an abrasion, but with a patch on the inside of the tire, the tube is staying inside just fine. The wear indicators are a nice feature, but Conti and no one else uses them as a selling point, or writes anything about how to read them, what their limitations are, etc.
overall good tires. experienced a sidewall cut and the tire is now finished. Conti should make the sidewall a little tougher. otherwise a fast rolling responsive tire.
The comments on this page indicate why testimonials are worthless and only consumer product studies should be used. First, do not switch your front tire to your back, it is not a car with inside outside wear patterns. Just keep replacing the back more often than the front. Second, unless your weight is well over 200lb, you do not need more than 120psi. 90 percent of riders need only 100-105psi. That is why these riders are having sidewall blowouts and flats. In addition, over inflation slows down a bike due to excessive vibration and will decrease performance in turns. Most of the problems indicated in posts are user error when it comes to inflation.
Love this tire. Period. Nothing lasts longer or functions better.
Love this tire. 95% of my riding is either going up very steep or coming down really fast. These last much longer than any of the many others Ive tried that come even close to the same weight and great cornering that these offer. Once the back is toast, I move the front back and put a new one on the front. No durability issues here. Only complaint: initial mounting can sometimes be a struggle.
I have a set of Conti 4000 700x25 black tires on both my bikes. Nearly 4000 miles on each bike. I run them 95 on the front 105 on the back and weigh 150. I have never had a flat and ride on Long Island roads in New York. If the tire wear indicators are for real they still show some good life. They have been remarkable tires.
First two came with new bike, performed well, lasted 3,000 miles, a flat or two, generally happy. Bought two new ones as replacements. Suffered first side-wall blowout 500 miles in, figured bad things happen, statistically insignificant. Less than 300 miles later, another blowout, this time in the middle of the tire. Week later, buddies Conti GP (not purchased from excel) let go on the bottom of a long accent in San Diego. Went back using my Gommitalia Calypsos (7 years prior riding trouble free on old bike). Same wheels, 1,000+ miles since the switch back, no issues. Yes the Calypsos wear out faster (2,000 miles vs. 3,000 miles). But at $65 a pop each, the Conti GPs lasted me less than 500 miles anyhow. I can get two Calypsos for about the same price as one Conti GP, save myself the $50, AND most importantly have confidence in the tire under me. My time and my safety are my prime comedies when choosing a tire, Conti GPs failed to deliver in either aspect for me.
I bought a set of these (23mm) after hearing all the hype and recommendations from a popular cycling publication.Brand new with latex, they ride very well in dry weather. They roll well, and seem to absorb a great deal of vibrations from the road surface. After a month I got my first flat. Then a flat a week for the next three weeks (both wheels). After that I switched back to normal tubes. Got two more flats. So I switched to Kendas beafy tubes. No more flats so far. Long story short, IMO the rubber compound does not maintain integrity well. It seems they break in too extensively to the point you can roll them on with no levers, and roll them off the same. Max PSI is 120, which is fine for cheaper tires, but not for this price. These tires are very comfortable recreational/training tires, and they should stay in that price range. I wouldnt have said anything if it wasnt for all the great reviews.
I have been riding for 25 years, best tires absolutely no doubt! I just got 4000 miles on the back and the front is going great with wear holes left at 5000! Just let the air pressure out after you ride to about 40psi, they will last way longer!
Say what you want I spoke to Continental and in the blackwall the 4000 and 4000s are identical tyres except for the spelling appearence of continental 4000 and Continental 4000S. Both are the greatest tyres
These are great tires for clinchers -- no doubt about it. Now, if you want to ride the best of the best, and youre looking for a tubular, go for the Continental Comp 19 -- it also has the vectran-breaker, and the chili tread compound ensuring great grip and no flats -- at least until you wear them out. In Ohio I get around 3,000 miles on a rear, and 4,500 to 5,000 miles out of a front. And with the new "for-carbon-rims glue" its a breeze to put these tires on! Only buy from Excel, they are not only a conti dealer, but their tires are FRESH as well!!!!!
Best clincher tire out there. More comfortable than Michelins. Great performance. Great grip on those fast hair-pin descents. My only complaint is that they seem to have gotten pricier as their popularity has grown. Almost as expensive as automobile tires but worth every penny.
After 30 years of riding tubulars (Conti, Vittoria, Clement), I expected clinchers to be more durable and these certainly are. I have 2500 miles on them without a single problem. The "feel" is slightly different than a tubular, but overall, the 4000s is a great tire and I dont miss gluing and repairing the sew-ups at all.
Great Tires Period !!! Very smooth ride. Difficult to stretch the tire on to the rim, but once theyre mounted its worth the effort.
GOT THESE TIRES LAST YEAR. HAVE RIDDEN THEM ABOUT 2400 MILES WITH NO FLATS AT ALL..THESE ARE THE BEST TIRES I HAVE EVERY RODE ON. FAST SMOOTH WHAT ELSE COULD YOU ASK FOR .THESE WILL ALWAY,S BE THE ONLY TIRE I WILL EVERY USE FROM NOW ON.
Go on and off without tools which is nice. Just rode a 32 mile "organized" ride which was supposed to be for road bikes but it was nearly all on dirt fire roads occasionaly mixed with gravel/glass/sand/nails/auto parts/household appliances/dead bodies. Im amazed that they still hold air but theyre fine. Impressive durability. (That goes for my Easton wheels too)
My Cannondale Super Six came with Maxxis tires and after two flats in the first week, I had the bike shop replace with the 4000S. After 2800 miles I have only had one flat, that was caused by a side puncture after hitting a rock. My training bike is also a Cannondale that came with Hutchinson, that also flatted twice in the first week. I changed to Conti GP 4000 and am now on my fourth set with over 19,000 miles and only 3 flats, total. I will not ride anything but Conti. I hate flats and this is the best tire for overall puncture and wear.
I bought these tires due to the rave reviews theyve gotten. After 300 miles Ive had two flats, a huge cut where the inner tube was poking out, and a huge cut on the other one that didnt go through all the way, and numerous indentations. Im a 155 lb rider and ride on normal roads. My first road bike came with their "low level" Ultra Race tires and I rode those for two years with only 3 flats and no cuts. Im dissappointed. I guess they are best suited for racing.
We have found these tires to be some of the most durable on the market, proper tube instalation and not riding through jagged road debris will lengthen the life of these tires - ed
Just ordered my 2nd set today. First lasted for 2500 miles and the wear indicators are still bearly visible. Long lasting, extremely flat resistant, great handling. Who needs more?
1500 miles on a set, and I am not yet down to the wear indicators. These are an improvement over the GP4000, and a big improvement over the GP3000 (still a great tire today). Grip (wet & dry) and braking are excellent. One of the few tires worth paying retail price.
I have been riding for 20 years and I believe these new 4000S tires are the best clinchers on the market today, Exellent Handling, Grip, wear and rolling resistance, A+
Fantastic tires! Great rolling resistence. Great mileage. Nasty, Nasty, Nasty!!!!!!! to mount on the rims for the first time.
I have been riding Conti"s of all types for the past 20+ years and must state that the 4000S is their best to date. The 4000 is a very close 2nd. The "S" feels similar to my Tufos in ride but I feel they are a tad more resistant to the glass cuts. This set of "S" tyres has just shy of 1,000 miles and it would appear that they will hold for another 600. Rotate them! Best bet: use this tyre as a race tyre and the "All Season" for training.
Couldnt disagree more with last post. These are a fast rolling tire. I also noticed they seem to last longer than standard GP4000. This tire is a winner..
New compound is sticky for excellent handling, it also helps cushions the ride similar to a tubular tire. However the rolling resistance is very high when compared to the Michelin pro 2 race tires that I am used to. One of my tires fell apart ruinning my Rolf Prima Vigor rims after a random blow out. No tires I have ever owned has ever fell apart exposing the rim to damage in a blow out like these tires, could be just one defective tire time will tell. Excelsports is great though they are working on getting me a replacement for warranty issue. Personally I am going back to my Michelins and waiting for the new pro3 race to come out.
I have been riding for 17 years now and this is the best tire yet! Best grip, best ride and no flats yet!
