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

Great Product. Great Price. Great Service. I'm a fan of Conti GP4000 SII. Durable. Smooth. No complaints.
Review by Gshines
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.

Tires are fast and I never feel like I am dragging like I did with my Vittoria Rubino Pro G. Third-party tire rolling resistance tests confirm this (web search). I have been over some unclean streets littered with rocks, glass, trash, and potholes here in the inner city and haven't had any issues so far. Tires are comfortable and absorb shock well. I feel like I can go extra miles on these as they are more efficient. Cruising along the flats at 23mph is no issue. Give 'em a shot if they are in the category of tire you are searching for. I also have my second set of Continental ExtremeContact DWS 06 tires on my car so I am very pleased with Continental's products at this point.

I switched to the GP4000 S when I rode a Motobecane Century Pro and a titanium Le Champion. I've never switched back, and the GP4000 S II is even better. The traction is good, and I have not flatted out since leaving the San Fernando Valley and switching to 700 x 25mm. Riding a Bacchetta CA 2 I have achieved some KOM's in my age group segments on Strava using these tires. When they go on sale, I make sure that I have one in my backup stock.

I've been using them for years and they are my favorite. Great ride and handling, rarely ever flat. The few times I've tried another brand, I notice the difference in handling right away and can't wait for them to wear out so I can get back to the Conti 4000S
Review by Bob
I have tried many different tires in the last 40 years of riding and the Continental Grand Prix 4000 as been the longest lasting tire with the best resistance to cuts and punctures of any tire I have used.
Review by Yon Gamarra
Not only had no flats in 12k mikes, (almost 20,000 km) they last for 3 to 4k miles. I am wearing the 3rd set and not planning to change brands.
Good grip but miss the colors.

I ride with a bike club in Florida in bike lanes on heavily used roads. After seeing how my tires hold up against heat and road trash, many in the club have switched to Conti GP4000S and think highly of them. A little heavy, but durability and ride performance more than makes up for it.

Continental Grand Prix 4000 S II 700c Road Tire
You simply cannot go wrong with these tires. Most have a favorite tire for a variety of reasons. My experience with the Conti GB 4000 S II have been great. Ride, train or race them. Run them with a tube or tubeless. Not a gravel tire but I can ride a couple miles here and there on a dirt road. I like to mount a new set of tires before a Grand Fondo and by the next one I have 2K 3K miles and ready for a new pair. If you need a change to get excited about riding, clean your bike, pop on a set of these tires and you have a new bike.

Just did Los Olas Aquabike in Ft Lauderdale this past weekend and prior to the race put on a set of brand new Conti's. Even though the sky's opened up and rained like crazy I was still confident enough of those new tires push hard enough to get 6th overall. Long time Conti 4000 user.
