I have been using this tire for a couple of years now. I can get about 1000 miles of use from the tire. I wish the tire was a little more puncture proof, riding in Southern Utah they have goathead thorns that wreak havoc on tires.

Excellent performance. Holds up well. The only tire I use.

This is a review of the Conti GP 4000s II.
This tire has it all, wet and dry performance, puncture protection, durability and a good price. This would be my tire of choice for general road bike riding if the Michelin Pro4 Endurance wasn't available for nearly $20 less. The GP4000s II wears better and lasts longer than the Pro4 Endurance but due to the cost difference the Michelin is a bit lower cost per mile.

These are my year round tires for training. They are durable and have good grip, even in wet conditions. I use these year after year. Wouldn't put these on my race wheels, a little heavy for that, but a great tire for everyday use.

I rated 5 stars on value because Bike Tires Direct has a good price on these tires. My local shops are much more expensive. I purchased 23s but have now changed my mind after a recent bike crash (broken collar bone). From now on, I'm going to run at least 25s. I have a new bike coming with 28 tubeless. I believe that we'll soon see that tubeless is the way to go.

I put a fresh set of these tires on before the 2017 Levi's Gran Fondo. I rode the IL Regno route which is 116 miles and over 10,000 feet of climbing. The roads in Santa Rosa and Sonoma County, CA are extremely rough and this route took us on a mixture of dirt, gravel, pot holes, you name it! The tires held up exceptionally well without any issues. Last year I rode the 4 Seasons tire, but these Grand Prix 4000s II tires inspired just as much confidence on any type of roads.

I always get 8-10 k miles. I rotate front to back as wear indicates.
Review by Oregonbiker
Great all-around tire! Great grip and acceptability durability! I rode these tires across the USA with only one cut and several flats in about 3000 miles....Another fellow rider used the Hardshell gatorskins....with even better durability...but definitely a slower tire than the GP4000 S II. I prefer these tires to the Specialized S-Works Turbo tires that came as original equipment on my Tarmac.

I have been riding for many years. Strictly a clincher guy, and I have found this tire to be a great ride.
Very durable, comfortable, and lasts a long time. Does not cut easily.
Also, and I agree, others have said the GP4000 descends very well.
I would easily recommend this tire.

Usual conti durability with the option to get reflective sidewall. not as durable as gatorskins, though.

I tried my first pair of Continental GP 4000 tires for my Southern Trans this past September 2017. I had been a Continental Gator Skin user as those tires are very durable but ride quite stiff and are not the easiest tire to get off your rims especially if your hands are cold.
I also reduced the air pressure to 90 F and 90 R based on advice from Lon Haldeman, Pac Tour Master.
So with the GP4000 at this TP the ride was very smooth, didn't feel any softness when climbing, and road surface absorption was excellent. Rode 1500 miles over 14 ride days and no flats.

This is a great tire for dual use as a racer and every day tire. Still the King of rolling resistance in my view.

Low rolling resistance, great race tire.
Review by dna5000
The GP 4K SII's are benchmark tires for many reasons they're fast, supple, grippy, puncture resistant. I've trained and raced on these for several years in the wet, dry, cold, heat, and they never disappoint. Not the kings of wear resistance but, considering how well they perform, it's worth the trade-off. Sorry...you can't have it all... at least for now. Oh, and they're definitely not the cheapest. That said, you're worth it and BTD typically has great pricing on GP SII's. If you're like me and consider the fact that your tires are the only meaningful connection between you and the road, and you'd like to keep it that way, they're worth it and deserve a hard look if you want a great all-around tire.
