ContinentalGrand Prix 4000 S II 700c Road Tire(Return to Product Page)

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!!

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.

Love the tires. they roll great and last a long time

Quality product and very durable. I have been purchasing Continental tires and tubes for years.

I really like this tire. I'm old school and race with them then use them for training on the road then to rollers.

Excellent road riding tire!!!

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

Great control & durability

For the price you can not beat them and they are darn good all around !

Going from Armadillos to GP4000 28mm was a eye opener. Lot faster, better riding and great protection.

No need to look further for a awesome tire.

Great tires, great handling, durability and speed.

I bicycle to work a lot and since using the Grand Prix 4000 S, the number of flats has gone down. Very happy with the rolling performance.

I've ridden Conti Grand Prix 4000 for years now. They are my go to tire for road cycling and when I have an event. I've used them for several half and full Ironman triathlons and they've never let me down. I live in Orange County California and since we don't get much rain, they are perfect for our dry, sandy conditions.

Have been using Conti tires for many,many years I am able to get 1,500 to 2,000 miles before replacement. Living in Chicago and with city riding the Grand Prix 4000 S II performs well and pretty much puncture-proof for the first 1000 miles. Probably go through 4-5 tires per season.

I ride nothing but Conti tires and will continue to purchase these affordable tire especially when BikeTiresDirect has them on sale.

The tires are outstanding. I put them on my spare set of wheels as well as my primary equipment. The price on biketiresdirect was so good, I also keep 2 spares available at all times! Very pleased with Continental tire as far as performance and durability! Even more satisfied with the customer service and prices on biketiresdirect!!

I've been riding Conti 4000 tires for a few years now. They wear very well and have been very durable. Currently riding across the USA on these tires

I'm an avid road cyclist and next to the bike that you may be riding the tires that you're riding on can be the difference from just a ride to an experience that's second to none.

I have been using these tires for 3 years. They are a great all around tire for the money. They have a great grip. They are fast. They corner well. They don't puncture easy. They are good for about 6000 miles.

I ride about 100 miles a week and no issues. The handling and speed are second to none.
