Continental Grand Prix 4000 S

I have nothing but high praise for the 4000 S. Top of the list is feel. This is coming from a tubular fanatic. This tire rolls and handles awesome. They are long wearing and cut resistant. I ride with a group of Schwalbe nuts, but I am the one without flats all season. The route map doesn't have where the township decided to drop new chip and seal last week. My tires don't show any gravel cuts.

I have put 1300 miles on this first set of 4000S. Was going to swap front and rear but there is no need for that yet. Front still has the center bead still there and the rear bead is gone but no where near worn.

I find my Nag rides the best at 118 rear 110 front. These are pretty sure footed in the wet also. Go caught in rain and 3 weekends in a row we have been fogged in in the NW Chicago area in the morning. No slipping even on an 18% climb in Bull Valley.

I'm sold. I have ZERO cuts on these and I have ran over some glass, large gravel, miles of chip and seal, miles of chip before they have sealed and some other stuff that made noise once I ran over it and you're waitting for a flat and NOTHING.

I have also come to love JUST BLACK TIRES with a small white logo.

If you are on the fence go for it. GREAT all around tire.

25 to 30 years ago I use to ride only tubular sew ups with silk casings for the outstanding ride quality. Modern clinchers are so much better. As a transition I rode VeloFlex open clinchers and like the ride quality but found them not wearing well and getting little cuts in the tread casing from sharp objects in the road. I switched to Conti in the 4000 S and have found these the best tires I have ever rode. Very round, Very smooth, Low rolling resistance, great grip on dry roads in hard corners, and long wearing. This Chili compound rubber is outstanding. This tire has the flat resistant belt that really works so I can run Conti's lightest super sonic race tube inside safely for training and greater road feel for a total weight of 260 grams per tiretube combo.

Love 'em! I'm a Michelin ProRace3 fan and the new GP 4000 S's have improved cornering and ride comfort compared to the old Conti GP's. If you like the Michelin's but you want to try something else for what ever reason give the GP 4000 S's a try.

I just got a set of the 4000S. Put 500 miles on them in the past 2 weeks. I don't want to like them, but I do like them. I loved pro Race 2's also. I swithed 2 years ago from the race 2's to Fortezza Tri Comp because they offered a white wall and 145 psi. Those were ok but felt slow and got very square after 1200 miles.

The GP 4000S are surprisingly smooth I weigh 160, Ride a C-50 with Ksyrium's SL3.

Front at 105 Rear at 113 and the ride is pretty **** good. Rolling resistance is really good and grip on turns excellent. I have ridden over some neighbor crap, glass, gravel and have no visible cuts. Also did about 300 miles of northern illinois farm road chip and seal with no problems.

I can already see that the rear tire has started to wear but barely. The Front still has the excess rubber line still down the middle. I'll put 500 more on in the next 2 weeks and give a new opinion. I wanted to hate these so I would try the Open Corsa EVO for the ride and the white stripe offered. But with the durability and ride of the conti's, I may be sticking with these.

I'm a big guy - 6' and 200 and soon to eclipse 5000 miles on the pair on my Bianchi. The wear indicators show 12 worn tread. This is my second season on them and I think I'll make it through next year as well.

If you are undecided on which tire to buy, try these.

Have had the tires for a month or so 100 miles per week and have had no problems. Ride on country and city roads. Have ridden on them on flats, rolling hills and in the mountains. Have had no problems even when descending on winding mountain roads at 40 mph.

Mounting was a breeze.

Would definitely recommend to anyone looking for great performance.

Tried Mich Pro Race and then Conti GP and 4 season. This is a step up from the GP4000 in my opinion. Great wear, super smooth roll and great traction I live in the NW and we get rain as well as good mountains. I like the wear indicator, easy to see when to swap front to rear to maximize tire wear. My bike is a Cannondale SuperSix and gets riden hard. These tire are the best I have riden on. The 4000S will be my choice when I ride across the US again in 2010.

Very impressed with this tire, after a season of riding it on widely varying surfaces, here in Western Oregon. Ride quality is on par with the Vittoria CX Open which seems to be the 'gold standard for many riders, though my ... doesn't agree, and just a notch below the ride quality of the Mich Pro 3.

Durability of the 4000S appears to be quite good--this is the only 'race' tire that I can ride on gravel without flinching. No casing cuts, and no flats.

Wear is better than either the Vitt CX or Mich Pro 3.

For real-world conditions, the 4000S is tops excellent durability, and ride quality.

Last year I was having the worst luck with tires, Bontragers, Kenda's even Michelin's. I finally settled on Gatorskins for the durability. But then I was looking for a winter rain tire and was recommended the 4-season, wow, not quite as durable as the gatorskins but a lot less rolling resistance. I used the 4-seasons early this year for a race in the rain, they worked fine.

Then I was looking for a good all around race tire about 13 of my team recommended pro race 3 the other 23 recommended 4000s. With already having good experience with Conti's I went with the 4000s, great decision. Now I can't really comment on their durability only because I watch wear I ride and I use the 4 seasons as training tires which are very durable. But the 4000s is a fast rolling tire, and with a high thread count it is pretty supple and the center of the tire will stay under you in sharp turns instead of harder tires where you end up riding on the side of the tire.

Last night I finally tested them out in a race in the rain, just thought it would stay dry long enough and I wouldn't need my 4-seasons. Well it started pouring right at the start of the race, I was nervous on the first lap, but by the final lap I was carving turns on the 4000s almost as hard as if it was dry pavement. I swear I was breaking some law of physics with these tires in the corners in the rain.

So I highly recommend 4000s for an all condition race tire. Light, fast, pretty durable, and STICKY!

I just replaced a set of Continental GP 4 Season tires with these, and the difference was night and day for ride quality and rolling resistance. The 4 Seasons are good tires, but roll kind of heavy. I had tried Michelin Pro 3s and Vittoria EVOs, but found them to be too delicate. I tried the GP 4000s and after 100 miles over the weekend, and riding over some harsh roads shoulders with glass, rocks, etc and quite a few small potholes, the tires showed no cuts or damage of any kind. The grip is good dry, haven't had them in the rain yet and rolling resistance is far better than the 4 seasons, and feels as good as the Pro 3s, but not quite as slick as the Vittorias. Overall, an excellent tire.

I ride 1000 milesmonth. Three months in the Colorado Rockies and six months in Tucson, AZ on every road condition imaginable. I usually change the tires at about 3500 miles. I had one flat about a year ago. I rode the GP4000 prior to the 4000S. Both are excellent tires. Grips the road well in most conditions and especially well in wet conditions.

Excellent tire! My first pair is still on the bike with 3400 miles on them. Ive already purchased a replacement set and they are in the basement on standby. I installed these tires in June of 09 and rotated them at 1800 miles. Im sure Ill get to 3600 or 3700 before the wear indicators which are great are low enough to make the change to the new set. I recommend these tires to all of my cycling friends.I'm a 170 pound rider averaging 100 miles a week. Additionally, Ive never had a flat with these tires. A great value when you can grab them with a 10% discount!

I've used these for quite awhile now and had really enjoyed them...But, recently changed out tires due to normal wear and replacements blew out the sidewall in less than 200mi. Replaced again and had a wonderful sidewall failure on a steep downhill. Don't know what's happening but I used to be able ride them until the tread indicators were worn off!

I ride 100 to 130 miles per week on Texas roads.

Recently switched from Gator Skins to the 4000 S.

The tire performes well and is reasonably puncture resistance BUT, and it's a very BIG BUT, I ruined both tires in less than a month due to cuts on the sidewalls. I have ridden the same roads for months on Gator Skins and never cut a sidewall. So yes it's a good tire for "clean roads" if such a thing exists, but, this tire needs major improvement in the sidewall.

Had a major puncture in first 30 miles. Huge cut in the surface coating. This has never happened to any tire on this particular circuit. Bought for durability. Did't get it. Bummer.
