ContinentalGrand Prix 4000 S II 700c Road Tire(Return to Product Page)

Even though it is rated as a racing tire, it works well for all-around riding. I get 2-2.5k miles out of the rear tire. Our roads are relatively rough and I don't get many flats.

Best clincher on the market

I run these in 25. Theyre comfy with excellent grip and feel. My only concern is ease of cutsnicks. I lost a 40 mile old rear to a small piece of broken glass, which I have never experienced in my life. I bought another one, regardless.

Since switching to 700X 25 over the 23, I've yet to have a flat! Think of that......I

'll never ride another tire.

Really like these tires. They wear very well. The ride is better than previous tires I have ridden. Zero flats or cuts on the tread. No problems handling chip & seal or less than ideal surfaces. Wish they would make a tubeless version.

Great tires. I upgraded form Mavic ykson equipe, so not a great comparison. However, the difference is quite noticeable. I used to get a lot of flats with the Mavic's but that may be the area i was riding. Since I have changed to these Conti, no flats. Not yet anyway! I have about 1500km on these now and they are grippy and smoother and I certainly feel more confident with them now since I have more time on them.

5 stars for the tires

4 stars for the price

Very good. Bought these to replace mavic Ykson tires. They got flats practically every time i rode. Read up on these Conti 4sii. Great reviews. Not the lightest, but very good for the riding i do, so far. I only have about 750km on them since purchasing these and not one flat. - I'll go ride tomorrow and get one now - thanx WB!

Price match from WB was great. However i see there is a big price drop in these at the moment. I got 23mm and 25mm running at 90 and 75psi respectively on different wheelsets. Huge improvement over what i had. I weigh 72kgs

Been buying these for years - never any issues - bullet proof.

I use this tire on my go fast wheel for days when I want to go faster than usual. It works! 44 mph instead of the usual 42 going down the steep part of Hillside from Clapshaw, and generally faster on the flats, especially with a latex inner tube.

Excellent tires for training in all conditions.

I've had these tires on front and rear for about 8 weeks and 1000 miles. During that time I've had two flats on the rear tire. We've had a lot of road work going on around here which may be a source of additional puncture producing debris on the roads. Other than that I've really enjoyed these tires. The roiling resistance is very good which makes this a fast tire. Handling in dry and wet weather has been good. The tires appear to be wearing well. They are easier to change than Conti Gatorskins and I have been able to get them off with two tire levers and back on by hand only. I would buy these tires again.

I'm running the 25mm width tires, between 80 - 95 psi on 3 of my road bikes. My experience with the Conti Grand Prix 4000 SII has been excellent. Smooth ride, great grip, low rolling resistance and better than expected durability. I've had 2 puncture flats due to road debris in approximately 2000 miles. No pinch flats, no defects, etc. Tires are pretty easy to mount too. I've had the earlier version of this tire without the Black Chili and I do believe there is a noticeable difference with the Black Chili - more grip, lower resistance. Occasionally these go on sale, when they do, they are a great value. For reference I've run Conti hard shell gator backs - In my opinion the Grand Prix 4000S II are far superior. I also ride Vittoria Open Corsa and Open Pave - the Conti Grand Prix 4000S II are more durable , the grip seems about the same but the Vittoria are just a bit nicer ride. Hope that helps.

This is my 2nd time purchasing the tires. Great service from Nate every time.

These tires seem to last forever! I keep checking the wear indicators but they don't seem to wear. The only time I ever get flats is when they have already gone a couple thousand miles.

Best tire hands Down. Bulletproof.

First time on these tires. Glad I got em. Roll very fast. Feel very supple. Nice and light. Reflecting strip on sidewall really lights up at night.

Tire rolls very well..have approx 500 miles on them to date and performs well... seem to handle the debis and gravel along our roads here very well

I have been running specialized s-works turbo tires for three years and love the ride ,feel and speed I get from them, but they wear out after about 1200 miles . I bought the continental grand prix s 11 on sale to see if they really preform the way I have heard . After 800 miles, they ride harsher, not as fast , grip pretty well , and seemed to hold up better ,but I will stick to my favorite tire , the specialized turbo

I've been riding these tires for years for general road riding on several bikes. I bought my most recent pair of Grand Prix 4000 S II to replace a pair of Schwalbe Ones that came stock on a new road bike. Schwable's are also high rated tires but never felt right to me. It's kind of all a matter of preference I suppose, but the Grand Prix 4000 S II always feel like their gripping the road better.

Long-lasting, great feel, even stops well in the wet. Not nearly as puncture-resistant as the Gators, but so much stickier.
