The new GP4000 S II really does deliver on all fronts, combining speed and amazing handling with impressive puncture resistance and extended tread life. Just like the original GP 4000 S, this is one of the fastest, most durable, and best-riding tires available. In fact, it's even better—Conti claims that thanks to continued R & D, they're able to improve the venerable Black Chili compound by 3-4% every year, so the new model has even better adhesion in wet and dry conditions, better durability, and lower rolling resistance.

For those not clued into Black Chili, this is the lingo Conti uses for their top rubber. As the name implies, it can only be made in black—hence this tire's all-black center tread. In a nutshell, Black Chili is an incredibly dense rubber, made up of particles roughly ten times smaller than those typically used in bike tires. Placing this wonder compound directly at the contact patch results in a tire that's not only more durable, but more able to conform to (grip) the road. It's also more resistant to UV rays, helping it to resist cracking and premature tire wear.

The tire also features Conti's patented Vectran puncture protection barrier underneath the tread. Originally developed by NASA in the construction of space shuttles and suits, Vectran is a tough but lightweight material that allows Conti to keep their tires extremely light while providing tremendous puncture protection.

The Grand Prix 4000 S II features a three-ply 330 TPI casing. Kevlar folding bead. Max inflation is 120 PSI. Claimed weight is 205 grams (700c x 23mm)

Great tire for 2018

Conti GP 4000 S II, great all around tires. I've been using these for racing and riding for the past two years. I would say I get about 2000-3000 miles out of a tire, so they do last a good while. They handle great and are nice and fast.

They also provide very good puncture protection for a high performance tire. I know there are other 'racing' tires on the market, but they are very light and thin and certainly put you at risk for flats. From my past experience, there are few things that take you out of a race as fast as a flat tire.

If you balance price, performance and protection I don't think there is currently a better tire on the market.

Disappointing sidewall flaw

I'm a longtime fan of Continental clincher tires, having used Grand Prix 4000 (including S II) , All Season, & Gatorskin versions. Past GP 4000 tires have lasted 2000-3000 miles treadwear with few flats and no sidewall problems, with ride quality noticeably more supple than the All Season or Gatorskin. But in a GP 4000 S II pair bought from BTD this season that had only about 1000 miles use, the one on the rear wheel recently had a sidewall hole directly under the reflective strip letting a bit of tube push out through it (analogous to an intestine pushing through an abdominal hernia). This required discarding that tire for safety. Fortunately I had an extra tire available to replace it. I don't know if this indicates declining quality control or was just a random event, but I'm disappointed in the exception to the GP 4000's customarily excellent reliability.

The Continental Grad Prix 4000S II road tire is the Go To Tire for cyclists.

I run the Continental Grand Prix S II road tire on three of my four road bikes. They simple are the best tire for the money. Good rolling characteristics, puncture resistant and long lasting. I have tried other brands with no where the success of these fine tires. Highly recommended for your road cycling both racing and training.

Great tire - improved ride

This tire has just the right amount of road-gripping firmness while delivering a very comfortable ride. I'm very happy with the feel and handling. Its a big improvement over what was on my road bike previously.

Best tire i've used so far

I switched from gatorskins a year ago and immediately felt the difference. They rolled much easier and felt lighter. Had a puncture cause I fell off my trainer so I had to go back to the gatorskin for a short time. I could really feel the difference. Not as smooth and didn't roll as well. Gatorskin is a great tire but the 4000 is far and above in my opinion. The price was great for the value. If you want a great rolling tire without breaking the bank buy these, you will love them.

Reliable. Just reliable

The only puncture I've ever had with Conti GP4000s was a pinch flat - my bad. For my road bike, I can't imagine a better investment, especially when they're on sale!

Can A Tyre Really Make That Much Difference?

Still in break in mode with these tyres, but I noticed the difference after just one ride!

Mounted and inflated, these tyres have a rounder profile than the Tendrils and that seems to make a world of difference. It is almost like riding on a tubular. They corner great, rolling resistance seems less I had previously, acceleration is measurably improved, and because of the rounder profile, shock transmission is lessened. They have not been on the bike long enough to really say if they are more flat resistant, but no problems . . . so far.

The folding bead fits mt Vision rims securely, yet I can could mount the tyre without and mechanical assist. I presume taking the tire off the rim will be just as simple. While classed as a racing tyre, I have no hesitation using these on a daily basis.

All around excellent choice and money well spent.

Great Tires

Ive been using these for awhile now and I am very happy with them. I recently tried the Attacks but the road cut them up bad, probably not the tires fault. I am back to the 4000s though, better karma.

Great riding tire.

My new Canyon came mounted with these tires, in the 28 width. I run them at 100 psi. , on DT Swiss wheels. Even more comfortable than my Mavic 25s on Ksyrium SLS rims. Ive had one puncture since I started riding the Continentals, maybe at 2000 miles. I did have a very hard time getting the tire off the rim. Vittorias and Mavics are much easier.

There are 2 little wear indicators on these tires. Looks like the rear will last the whole miles. I bought 4 when they were on sale, so Im committed.

BEST BALANCE OF, DURABILITY, MILEAGE, PERFORMANCE AND VALUE...

Like many cyclists, I've tried a lot of different high performance tires looking for that one tire that excels at everything. In the end, I use GP4000's on all of my wheels. A few tires have a more supple ride, a few corner better. Other tires are miserable to fit or have weak side walls or get lousy mileage or are prone to flats. GP4000,s just inspire confidence. They corner well in wet and dry, I get excellent mileage, (3,000 mi. plus), average about 1 flat per year, never had a side wall problem and they have relatively low rolling resistance. I've hammered these tires on So. California roads and the GP4000.s always get me home safely.

I purchased sets of 25 and 28mm, cutting the side wall of each set on the rear within 250 miles, disappointed.

I both race and do long distance Randonneuring, so I purchased the 25mm to race and 28mm for the long distance rices. In the past I've had great success with Continental tires. Unfortunately not with these tires, cutting the side wall of the rear tires of each set within 250 miles of use - disappointed.

A great tire.

These are by far the best road tires I've ever ridden. The roads in my area are riddled with debris as a result of all the rain we've had here on the east coast so having tires with extra puncture protection is a must. I realize no tire is completely impervious, but these up your chances of not having a flat.

I ride early mornings so reflective stripe made sense. After about 100 miles I noticed a half inch separation which I reattached with glue. No problems otherwise.

Best road tires for my needs

These are tough, flats occur like anything else but tend to be very few and far between. They are very hard to mount at first because of stiffness but it gets easier after some use. They are also comfortable on a long distance ride. My only other qualm is after about 2,500 miles or so, they tend to shed some threads fairly regularly though its probably about time to replace them by then.
