Grippy and puncture-resistant.

Continental’s Black Chili Compound is famous for its unusual combination of grip and durability, and the Grand Prix 4000 S II Tires are the company’s flagship road product. The GP4000s, as they’re commonly called, can be found under riders and racers from seasoned pros to weekend warriors. Continental has upgraded the long-running GP4000s with a strong, puncture-resistant Vectran yarn made from liquid crystal polymers. This yarn doesn’t cause any kind of "dead" feeling in the tires, and it keeps pesky rocks, glass, and thorns away from your tubes.

These tires rock!

  • Familiarity: I've put it through the wringer

I discovered these tires a few years ago and now they are all I use (but I will be checking out the new 5000s). I ride a mixture of pavement & gravel and these things are durable (over 3000 miles on the rear tire), not prone to pinch flats and grip great.

Great tires, but fragile sidewalls

    I have ridden nothing but Continentals on my BMC SLR01 and previous bikes. I have ridden that bike more than 14000 miles in the last two years. Other than two flats which were, in fact, punctures (one ripped out the sidewall and I rode home with a $5 bill wrapped around the tube) I had only pinch flats caused by experimenting with lower tire pressures. The sidewalls are pretty fragile, but that also gives the tires that wonderful feel going around corners. Its a trade off. No tire is going to be totally puncture proof in my experience. It is only a matter of when, not if. All of the Conties I have owned have given me full service life right down until the wear dimples disappeared with the exception of the sidewall puncture which happened the day after I mounted the tire. There is a lot of sharp gravel on the shoulders around my area due to construction. I studiously watch for and avoid it, so I suffer very few flats. The pinch flats were my fault. I got about 5 over a two month period. Once i inflated the tires up to my normal 80 PSI they stopped happening. Since then, over the last 7 months I had one tiny sliver of glass which caused a slow leak that didn't show up as a flat until the next morning. I can't gainsay with other peoples' experiences. I can only say that I have used Continental GPs in all of their incarnations and, years ago, Supersports, and nothing else. I wait for deals like the present one and buy extras to keep on my shelf for when I need them.


    • Familiarity: I've used it several times

    I hate to be "that guy" but I've had a really bad experience with my Continental Grand Prix 4000s II's. I ordered my tires last month and the one is already trash. The sidewall ripped and the puncture protection has been mediocre at best. I'm still a 4000s fan but maybe I just got a bad batch. It stinks because I'm not made of money and really can't afford to buy more tires too often. It's not Competitive Cyclists fault at all but it's just where I ordered them so I just came back to write my honest review.


    So are they going to replace under warranty? Or send you another tire? This is 2 negative reviews on production qc back to back. Maybe someone needs to check on the batch number and call continental for a possible recall? I would imagine that competitive or backcountry would back this tire up as they stand behind their stuff. Am I right?

    William, I'm not sure what's gonna happen but I've contacted Competitive and Continental already so I'm just waiting for a reply. It's a shame because I love these model tires but it's gotta be a bad batch or something because my tires are still very fresh and the tire I had on my front wheel (in the picture) is now trash. Sidewall has blown out and it's frayed by the bead on about 5 inches of the tire too.

    Within two weeks, I had two 4000s II's get catastrophic sidewall gashes--where I had to call for rescue because the tire was ruined. I gave up and now use a Specialized Armadillo in back, all I could get in a hurry. The sidewall was always a weakness, but this was just too much.

    Have run nothing but these for three years. They're very good, but not perfect.

    I got a puncture a month ago on the contact surface of my rear tire one day after installation. Was a minute hole, but that's supposed to be the strongest part of the tire. Flatted once last year.

    I find that flat spots develop between 2K and 2.5K miles.

    The sidewall blowouts are troubling and dangerous. Happened to me in Oct 2015 just a week after I bought my bike and swapped the stock tires for these. Maintained control, but could have been bad.

    Hello Dan!

    I really appreciate the review, as it's one of the only ways we can get real world feedback on any of our products, be it good or bad.
    I have always been a major fan of the GP 4000 tires just like yourself, and have had both sets of my current generation (also purchased within the past three months) going full tilt since I've installed them. Sidewalls are always a hairy subject when it comes to tire longevity, as though they are designed to be resilient, are still subject to any rock, pothole, or random metal lying in the street at the opportune moment for us to ride perfectly over them and gash what is arguably the weakest spot on any tire. The durability of the GP 4000 is sometimes mixed up with the durability of the Gatorskin tires when it comes to being incredibly resilient. And although the GP 4000 carries the thermoplastic yarn to help increase resistance with punctures, it's really designed to be a lighter weight tire that has fantastic grip.

    I'm happy to get you set up with a replacement in this case. You've only recently purchased these tires, and we stand behind our customers when it comes to situations like this. Please feel free to reach out to me personally at and I'll get you set up with a return label for the current tire at no charge, and a new one out the door as soon as we can get your account pulled up!

    I also appreciate you taking the time to note that this is out of the hands of Competitive Cyclist, but as I mentioned before, we never want our riders to be left out in the cold in regards to a product within such a short amount of time in purchasing it. Bicycle companies spend money in R&D to try and prevent this from happening, and in the rare cases that it does, we like to be the fail safe to help out if we can. I hope this helps a bit and look forward to hearing from you in the near future!


    • Familiarity: I've put it through the wringer

    I was a loyal user of the tire, but two of the last three I purchased have been defective out of the box. Not sure if I've just gotten unlucky or if there is a quality control issue at the factory, but I'll be moving on to something different.

    Mine is also defective. They're still practically brand new and my one tire has already blown out the sidewall and part of the sidewall where the bead is located is also frayed and defective.

    my go to tire

    • Familiarity: I've put it through the wringer

    i always buy continental tires. they hold up great

    Best all-around tire

      This tire has been with my over dirt/gravel roads and on unswept streets. It is reliable for thousands of miles of riding.

      Holding up well

        A couple hundred miles in and holding up nicely.

        Best all-round training tire I've found

        • Familiarity: I've put it through the wringer

        After years of experimenting with different tires and brands, these are the best tires I've found for daily, year-round, training. I live in Colorado, and we have a fair amount of road debris. Every tire is going to flat, but these seem to have the best balance between road-feel and durability. They're relatively light-weight too, which I appreciate for the mountains. They corner well and their grip is good also.

        Typical high end clincher

        • Familiarity: I've put it through the wringer

        I find that most 120tpi clinchers are all about the same and the Contis are no different. They are very sensitive to inflation levels and tend to smooth out slightly under inflated. Puncture, cut resistance, and durability are good.

        The worst.

        • Familiarity: I've used it once or twice and have initial impressions

        It just ripped open in my driveway. The center seem just split. Thank God I was just at the house.

        Oh wow. That is not normal. Please let me know if you need help getting a new tire


        • Familiarity: I've put it through the wringer

        This tire has been great. They aren't kidding about the puncture resistances, although I have gotten a couple of flats, I didn't struggle a bit getting the tire on and off which is always relieving. I have had multiple sets and I don't think I'll have the need to roll anything else.

        Great Tire!

          The Continental GP 4000s are great tires! They are super grippy and dependable. Don't forget to buy a pair!

          Favorite Race/Training Tires

          • Familiarity: I've put it through the wringer

          Absolutely love these tires, use them as both a training and race tire. They do not come as a pair, so make sure to grab 2 of them. A little bit on the higher priced end, but well worth it.

          do these come as a pair?


          25 is the new 23

          • Familiarity: I've put it through the wringer

          25mm is the new 23mm. The larger wheel is noticeably more comfortable than the popular 23 of yesterday. The increased rolling resistance is also negligible so no need to worry there. Solid tire choice for racing or training.

          Go To Tires!

          • Familiarity: I've put it through the wringer

          Great grip, easy rolling, dependable! Re-ordering more right now :-)

          Why go tubeless?

          • Familiarity: I've put it through the wringer

          These tires roll just as well and grip just as well as a tubeless setup. Don't deal with sealant and get these race ready clincher tires! Especially if your bike will accommodate 25mm tires. Warning these puff up a bit wider on most wheels. I have raced these for three seasons and as my skills on the Crit course progressed these tire kept my grounded. Made with Black Chili " keep the the rubber side down" compound you can rail corners and get to the finishing sprint faster than your race companions. Hope your not afraid of heights, you'll often be on the top step with these tires installed on your race wheels.

          fast and considerably light

          • Familiarity: I've used it several times

          use the tires for racing only, not the fastest or lightest but they provide good grip and puncture resistance at a reasonable price.

          can't go wrong with these tires.

          Light and Fast

            Rolls fast with great puncture protection. They are an easy way to keep your wheels light or shave some weight if you have been using a heavier training tire.

            Best tires ever!!!

              Can't say enough good things about these tires. They ride and grip better than any tire I have used before.
