This are the best all around tires period. Excellent price and costumer service from biketiresdirect.com make it even a better purchase.

Wears very well. Handles good. Getting 2500 miles out of the set I have now with 1 rotation. If you rotate at 500-600 miles you can get more.

Review by Dave P
Got this tire in a 20mm to fit an old back up TT disc. So glad that conti still makes this option as 20mm tires are fading out in the TT world because of RR(rolling resistance) tests. Raced all year long and and a few training rides still super sticky and fresh. Fastest all around tire in my opinion.

Really like my new tires. Ride is very smooth. I highly recommend to anyone needing new tires to consider getting a set of these.

I mounted these GP4000 S II tires on my New Zipp's, 404 Carbon Clincher's, WOW!! What a difference in ride and performance. I picked up a mile and half per hour!!
Love Them.

Review by Schwartzman
The Conti GP 4000 S II is a fantastic tire that is long lasting, puncture resistant, and yields a fast yet soft riding experience. The gripping power is excellent, even in wet conditions, yet soft enough to absorb the contours of the rode for a pleasant ride experience. a bargain at BTD prices.

I normally get 2,000 miles out of these tires. Rolling resistance is great. An important feature is installing tires compliant with tire errors. Unfortunately, finding those arrows can be quite difficult.

The gold standard to which all other tires are measured. Great grip and longevity are what you can expect from the conti Grand Prix 4000 S II

Put 2 new 4000's on a new set of HED wheels. In 2 years, ZERO flats (durability), sub 430 century (speed). Replaced the rear tire after 1 year, the front is still going with wear indicators still visible.the PERFECT tire
Review by Longhorn
Not as aero as 23's on my wide ENVE rims, but MUCH less abusive to me on the crappy strips of broken pavement that qualify as a road in Houston. I'm running 78psi in them and the ride is sublime!
One caveat is that the bike steers a bit quicker and is a bit more unstable in sprints, but I just need to readjust to that effect.

Great Tires. Great Price!!
Review by Igrex
I went through many tires including Michelin, Schwalbe, and Continental and this is the tire that I put on all of my road bikes now. Fast enough to best my cycling bodies on almost every sprint, and durable enough to train on. I've even gone on some gravel and offroad on it.

Have been riding Conte GP4000 for a number of years. There is no question, Continental is the best tire out there.
