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

Very durable summer tire, I use the 25 for training and the 23 for racing.

great tires good price fast shipping what else is there?

I just completed 2014 Ride the Rockies and Triple Bypass ride in Colorado. A very fast tire!

Using them on Zipp wheels in and iron distance triathlons. Confident ride.

Used these for the past few year, no flats averaging 4,000year in goathead territory. Durable is the word

Best tires

I have been using these tires for a lot of years and am really satisfied with them. Very few flats and very good mileage out of a set. No complaints from me so I will stick with them.

I am judging by me experience with the 4000s, 25c. I took the rr out of service after about 5000 miles. It still had some life in it, but I didn't want to risk a flat in winter weather. This is the longest lifespan I've experienced from a high-performance clincher.

Great tire as continentals are. Switched from 23 to 25 cm and the ride is smoother, with same great handling. Glad I went to the 25cm size. Cant go wrong with Continental tires.

Very smooth ride, highly recommended

These tires are a proven product. Work well in the wet as well as the dry. Wear well and have a positive feel.

I have used Gran Prix 4000 for years. They have lasted much longer than Gatorskins and have been wonderfully free of defects, unlike other brands that I have tried. They roll well too.

great tires, rolls smooth, 500 miles so far and just one puncture from a staple.

First use, cross country from Santa Monica to Saint Simons Island Georgia on one set of tires. Am a heavy rider, 200 lbs. fewer flats, especially from goat heads. Best tire I have ever used

Just started riding with these tires, so far so good !

13,596 miles on Michelins with no problem. 19.6 miles on Contis with a devastating side wall puncture .

I bought theese to replace some Gatorskins. I am very satisfied and Continental only tires i will buy.

I've been riding over 100 miles a week and have recommended the tires to my friend
