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

My favorite

  • Familiarity: I've put it through the wringer

These are my favorite road bike tires. I have gone on countless century rides with these with minimal flats. It's a good balance between flat protection and performance. I have a stock of these tires and only these tires for my road bike. For bulletproof super heavy touring tires, I have the Schwalbe Marathon Plus in 700x35mm.

Great Race Tire

  • Familiarity: I've used it several times

I use these on my race wheels as well as my training wheels and they are great! I have had very few flats and they seem to hold up great, won't be switching it up anytime soon.

Best all around

  • Familiarity: I've put it through the wringer

I don't want these tires on my wheels anymore, the rolling resistance is so low I felt I'm taking too much advantage against my club riders who are not using these tires. I gave other brands a try but I kept coming back to these tires... the durability is outstanding comparing to others.

The best tire

  • Familiarity: I've put it through the wringer

To echo many of the reviews here, I believe these are the best all-around tire available. They've got confidence-inspiring grip, solid durability, and wear better than any tire I've ever used. No other tire checks as many boxes as well as the venerable GP 4000S II.

Best Around

  • Familiarity: I've put it through the wringer

I love these tires. Although, they are a little heavy, they make up for being extremely durable. I road over 3K miles last summer with minimal flats. They grip the road nicely, which makes me feel confident on fast descents.

I honestly do not ride anything else. My favorite size is 25 X 700, but I have yet to try out the 28's.

Ride True

  • Familiarity: I've used it several times

In contrast with the tires that came with my expensive new bike these run perfectly true. A bit difficult to install. Ride extremely well . Can't comment on durability yet but seem very high quality. Am a recreational cyclist and have been riding for over 50 years so I've used many a tire among other cycling equipment. Owned a Trek when they were hand made in Wisconsin, wow what a bike!

WRONG SIZE -- More Like 30+mm!!!

    I have run these in the 23mm & 25mm, so when I bought a new bike this winter that had Continental Gatorskin 28mm tires on it, I immediately bought the 4000s IIs 28mm to put on it this Spring -- they DO NOT FIT!!!

    These are NOT "28mm" tires, when measured IRL, they are 30+mm, and rub the frame on a bike that can comfortably run other models of Continental tires that are 28mm.

    I am not sure why Continental would make their 28mm tire over 30mm wide, but they did, so don't do what I did and blow $120 bucks for 1 trip around the block on "28mm" tires that are the wrong size -- unless your bike can clear 30+mm tires -- these "28mm" tires will NOT fit!!!

    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.

      Same. I had one new rear tire destroyed by riding over a sharp rock. I haven't had that happen since I had Veloflex tires on my bike. There are enough reports of sidewall failures that I think that is this tire's weak point. That, and ride quality. But the grip and cornering confidence they give is phenomenal.

      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.
