Description

Like the outgoing GP4000 S, Continental's Grand Prix 4000 S II Clincher Tire continues to use Black Chili, but now has Vectran technology to boost puncture protection. Vectran is a multi-fiber thermoplastic yarn that is made from a liquid crystal polymer.

Claimed to be stronger than steel, this offers additional resistance to penetration from road debris while being ultralight. Combined with Continental's Black Chili rubber compound, super-tiny carbon black particles incorporated into the rubber formula, the GP4000 S II is versatile enough for race wheels or training wheels.

The tiny size of Black Chili particles allows them to mold to variable road surfaces more readily. It gives the tire greater ability to conform to imperfections in the road surface for excellent grip in demanding situations—such as high speed cornering—while also reducing rolling resistance. Since the Black Chili particles are so small, more particles fit into the contact patch of the tire, reducing tire wear and increasing tire longevity.

  • The most popular racing tire we carry
  • Increased suppleness reduces rolling resistance
  • Unrivaled traction and road feel
  • Vectran technology reduces puncture risk
  • You know Conti's GP4000 tires are the best, and they know you know

A solid standard

  • Familiarity: I've put it through the wringer

When deciding which tires to put on my bikes, I focus on four main categories; durability, grip, speed (rolling resistance) and weight. I have yet to find a tire that hits all four categories with the same high performance standards as the Continental 4000s.

Great Tires, But..

    I've had good luck with these and really enjoyed them. Then, during the past two weeks the sidewall tore on two of them after riding over some debris on the road. Brand new ones too. I'm thinking that I may have just been unlucky enough to ride over some sharp junk in the road but that's two too many so I'm going to give the Grand Prix 4Season a try for now.

    Still the one, but doing another comparison

    • Familiarity: I've put it through the wringer

    ....Because that's part of my job and frankly, I can't resist.
    The GP 4000 continues to be my go-to for every condition and type of riding. Reliable grip, better ride quality than the tpi would suggest and last long enough to get more than your $$$ worth. 25mm is the happy medium, but more frames are clearing 28mm these days so that may become more of a norm. These are on my list to try in the 28mm size.
    Planning to try out the Vittoria Rubino Pro G Plus to see how it stacks up. Stay tuned....
    Send any questions my way in the meantime!

    Great tires

    • Familiarity: I've put it through the wringer

    Used on a BMC SLR02 with standard rims. These were 25c and I ended up moving them to another bike and buying a set of 23c as they felt faster on 15c rims. Tires are great --- BMC clearance a little tight. Competitive Cyclist is my go to store for components!

    Rad tires! 28mm dont fit Tarmac

      Thought it would be worth posting to maybe help someone else out with the constant "how wide of tires can I ride on my bike" question. But got these tires in a 28mm for my boyfriend and they did not fit on his 2016 Specialized Tarmac, there was rubbing on the frame. Bummer! Otherwise amazing tires, you cant go wrong with these.

      Excellent Balance

      • Familiarity: I've put it through the wringer

      These are a long lasting performance tire, pretty much the longest lasting performance tire I have ever ridden by quite a lot. Typically I will get 800-1200 miles out of a tire, but with these I am getting more like 1400-1600 riding the same terrain.
      They ride pretty darn nice too.
      I have ridden tires that grip better in corners and are more supple, but they always have the shortest life spans.
      The only time I have had one of these tires life spans cut short is with sidewall damage. These are no more or less protected sidewalls than other tires in the category, but if you need something truly bomb proof and do not care about ride quality, check out the gatorskin version from Continental.

      the best tires

      • Familiarity: I've put it through the wringer

      I've been using these for years and wouldn't buy any other tire. I ride a lot of nasty pavement and some gravel (the road to my house is gravel).

      Best Tires I've ever ridden......

      • Familiarity: I've put it through the wringer

      I ride on roads (and shoulders) that are not well maintained. Welcome to L.A.! We don't have money to clean and fix our roads so they can be nasty to tires. I can ride these for 5 to 6 months without a flat and generally replace them when they finally show signs of wear. I would rather replace them than take a chance with well-worn tires. I consider them an "essential" accessory for the serious cyclist. Don't even think about it. Just buy a pair. You'll be glad you did!

      Nice tires...when they last

      • Familiarity: I've put it through the wringer

      I've had four sets of these tires, and three times they failed by developing tears in the sidewall. The one pair that lasted made it to 2000 miles, but one tire tore after 300. If you ride with these tires, don't go anywhere without an emergency tire boot!

      I have had the same problem. Sidewall tear around 300 miles. Tire boot almost got me home before the sidewall ripped almost 4 inches long and even the boot could not fix that.

      Can you run these tires tubeless? Has anyone tried it?

      Don't even think of it, sidewalls too thin and a kevlar bead not carbon. With these tires, you get the best road feel using latex tubes, but if you want more protection against flats, try butyl tubes with 2 oz Orange sealant

      Unanswered Question

      Did Conti change the actual width of these tires? Two of my friends have them labeled as 25mm. One measures 25mm wide, the other 27.5mm. The rim widths are nearly the same. The latter purchased over a year ago, the former more recently.

      Great Tires

      • Familiarity: I've used it several times

      Bought a new bike with cheap tires. Replaced them with these tires and they have been great. I purchased the 25's and they have made my ride very smooth, especially in the rain. Great product.

      my go to tire

      • Familiarity: I've put it through the wringer

      I've bought several pairs of these now. First and foremost they perform excellent. On top of that they wear pretty well and protection is decent.

      Great tire, some quality control concern

        Love the tire, ridden heavily on my tri bike but now that I have some wear on the treads of the current set I am finding bubbles in the rubber. No issues yes, but definitely concerned about the structural integrity based on what I am seeing (image below).

        Great tire, some quality control concern

        Those are suppose to be there. It indicates when you should replace the tire. When you can't see the "hole" anymore, time to replace.

        I will second Jae's comment - these are wear indicators and are supposed to be there.

        Hello Gary, those tine holes are like thread marks on your car tires, perfectly normal, nothing to worry about, when you can't see them or are half moon shaped then that's when you need to replace the tires, I hope this helps

        If you mean the holes in the tread as pictured--those are tread-wear indicators put into the tire by Continental. When the tires are worn, you will barely see, or will not see, these holes. It will then be time to replace them.

        Those are not bubbles - the tires are made that way - they are tread wear indicators ... when you wear the tire down so you can't see the holes any more it is time to change up your rubber ... if you look there are also arrows on the side wall ... the tires are meant to rotate in only one direction (Ive seen people mount them the wrong way)

        They are the wear indicators, not bubbles. When they disappear it's time to change the tire.

        They are the wear indicators, not bubbles. When you no longer see them it's time to change the tire. This is explained in the instruction sheet.

        My primary tire

        • Familiarity: I've put it through the wringer

        Been using these for years. Great feel, the durability is excellent. I am not a light weight finesse rider....my MTB instincts some times get the best of me.
        Just jumped on the deal offered at Backcountry today so I have my next set ready. The tires do last a long time but my current set is finally reaching the end of their service.

        Move Over Losers

        • Familiarity: I've put it through the wringer

        After putting a couple thousand miles on these tires I decided it was time for a review.

        First of all.. if you've got deep dish wheels and don't have a lot of experience putting on tires.. You may want to take them out of the box and lay them out in the sun in as much a circular shape as possible. This helps a lot. I was able to get them on with just my hands & a bit of brute force.

        This is a long lasting tire. I would not put anything else on my bikes. There's a reason its the most popular tire on the road for racing, century rides or training. Yes, it's expensive but the performance and puncture resistance is sooo worth it. Changing from the stock tire that came on my first bike to the 4000 S was a night and day difference in feel and handling. The center of the tire has extra rubber that dampens the road imperfections and I assume aids with puncture resistance as well, 1 flat in three years. It's also probably why they last so long.

        Move Over Losers

        Karissa,
        I have a question related to the 25mm tire on your 404's. I built Reynolds assult SLG wheels this year and also have a pair of HED Ardennes + SL. The HED looks like a wider rim, even though both noted 25mm,
        Having 23 mm GP 4000 on my HED wheels lays them out at a nice 25mm width, Happy with that.
        I built the SLG's with S works tires (2 for 50$ special) in a 24 mm. They mounted at a true 24 mm on this wheel. I have burned the rear one out and replaced w/ a new 23 mm GP4000 as usual. I have always read these to be somewhat bigger in 23 or 25 so I stay at 23 and a bigger/wider wheel.
        Mounted new on the SLG wheel, they measure 23mm though. Hmm, maybe they will widen as they get used but i'm considering the 25mm instead, as you have.
        Can you tell me how wide that 25mm tire lays on your wheel? Most say the 25mm tires opens to a 27'ish width, where the 23 stays more true to size. My concern is I ride a Ridley Noah and it can be tight in the rear, 27 would push it. Thanks for the info and sorry for the length.

        Great Tires

        • Familiarity: I've used it several times

        First ride on new 700 x 25 tires. Much smoother ride than the tires that came with my Cannondale Synapse Carbon bike. Those were Mavic Aksium. Encountered several streets being repaved and the tires handled those roads well. Even when standing to go up a hill, I felt a little more give in the tires which made going up the hill easier. Probably due to lower rolling resistance. I had one high speed turn on my ride and I felt like the tires had a solid grip on the road and it turned into a non issue. Highly recommended and $20 cheaper than at my local store. Let's put it this way, these tires made riding more fun.

        What size did you you put on the Synapse? I also have a Synapse and am looking at these tires. I've got the Rs11 rim though. I've heard that they may be fatter once installed. I was hoping to get a 28 on but the 25s might be the largest to fit.

        Geoff, you can fit 28mm easily on a current-production Synapse since that's what it comes with. You can fit up to 32mm on the disc models of the Synapse.

        Great Riding Tire

        • Familiarity: I've used it several times

        I've not had much brand loyalty in the past few years, buying the best tire that I could get at a good sale price. Generally I found that all the tires in the class of the Vittoria EVOs, the Vredestein Fortezzo etc. were basically the same. Then I bought the Conti 4000sII at a great sale price. These tires outshine all the others that are considered race tires. I bought the 700X25, pumped them up to 100 rear and 95 front (I ride the Hed Ardennes Plus LT wheel) and found the ride to be exceptionally smooth and fast. I can't comment yet on durability (honestly, we don't expect great durability out of a so-called racing tire) as I only have about 400 miles on the tires.
        I now will have brand loyalty- these tires are my go-to brand.

        Hello,
        Did you try the 23 on the HED wheel to see how it fit compared to the 25?
        I have been running Ardennes and now have the plus SL. Trying to mount my past model 23, S model and S2 model, both were super hard to mount. In fact, I pinched a few tubes in the process, and I'm not new at this.
        I'm concerned that the recent model is tough also.....

        To Jake
        I have mounted some Vittoria and Vredestein 23s to the Hed wheels and found it very difficult. I think it is due to the width and depth of the wheel rather than the size of the tire. Even the very experienced mechanic at my bike shop found mounting a 23 tire to the Hed wheel very difficult

        wow that's high pressure, eg 200 lb guys typically ride 75/80 f/r with 25's mounted on Ardennes Plus

        Always dependable

        • Familiarity: I've used it several times

        The 4000 is a case of not fixing something that isn't broken. If I need new tires I don't even think of trying anything else. I did move up to a size 25 after years of 23 and they are great. I'm not sophisticated enough to note any specific differences between the 23 and 25 on the road, but the 25s seem very stable and grippy in the corners. And my Cannondale Synapse had plenty of room for the wider size so I'm happy.

        The one I keep coming back to...

          In line with the other reviews, this is the best all around tire I've found. It's the right combination of light, low rolling resistance and durability. It may not be the absolute best in any of those categories, but it is close enough to the top in all of them to make it my continuing choice for all my riding.

          These do run a bit wide. I tried 25 mm on my 2012 Cervelo R5, and it fit, but the clearance was very close. Too close, so I went back to 23 mm, and on Zipp 30 Course rims, the tire measures 25 mm wide when mounted.

          The 25's will likely fit on newer frames, but just too tight on the older R5 frame. Other than, no issues at all. Great tire.
