ContinentalGrand Prix 5000 Road Tire(Return to Product Page)

After too much research I decided to go with GP4000s for a middle distance triathlon. After several hundred miles tires are still in great shape. It appears there is a reason most triathletes use them - seems like the best combination of durability and speed (not that a tire impacts my speed much). If they are good enough for the pros they are good enough for me.

First of all, I have bicycled consistently for 59 years (I am 66 now), including racing in the various categories on various single and tandem bicycles (and wheel sets). I learned how to repair sew-ups when I was in my teens and have used probably every tubular and clincher tire on the market. Other Continental tires never gave me any problems. These specific tires-2 in a row using different brands of tubes-blew out while riding around 45 miles. I purchased 2 tires initially, for the front and back. While riding, the tire literally separated along the bead (first time I have experienced that) and subsequently the tube blew. I reordered the same brand, using a new tube, and after about 45 miles, this tire also blew out-separated along the bead (same place, same problem). This was not the case of a pinched flat or underinflation or torn sidewall or bad tube (I used two brand new tubes, different company-and not thins- and the right size). So, I concluded that there was a manufacturing flaw. I will not give up on Continental tires but will give up on this specific model.

My go to tire! Great traction and a good balance between durability and performance.

My only issue is this tire is prone to sidewall punctures which renders the tire unusable.

These tires are the best on the market today! Theyre fast & smooth as well as long lasting!

I bought these as my everyday tires and for an upcoming ride across the length of Kansas. 565 miles, some of it on secondary roads, not flats, no problems.

I have been riding on Grand Prix 4000 for many years! I have never had any problems and I am 210 pounds.

I normally ride around 3000 miles each year. Not too bad for 75?

I just switched my front tire to the rear only because I like to keep a new tire on the front. The tire I moved had over 4000 miles on it and still had plenty of mold dimples showing!

I have read several reviews on this tire that says that they dont last?

I am heavy and ride rough Virginia roads and even some gravel roads, but these tires hold up for me! Just one old farts opinion!

These tires ate awsome. They were delivered right on time. Easy to put on. I have put about 200 miles on them no flats. And the bike handles better and is actually faster with these tires on it.

Performance and rolling resistance are excellent. My only issue is this tire is prone to sidewall punctures which renders the tire unusable.

So far this is a good tire. Rides well and handles the cracks and black top bumps and holes well.

I like everything about these tires, and there is nothing I can complain about.

Performance and rolling resistance are excellent. My only issue is this tire is prone to sidewall punctures which renders the tire unusable.

Excellent tread wear! My go to tire!

Have been running GP 4000S for a long time. They have a very long life span and hold up great to our multi-condition type days. I always recommend them to people!

Thought I was crazy. Replaced a pair of Specialized roubaix 70028 with the Conti 70028 and the tire was rubbing slightly both front and back. The continentals measured 32 wide and the specialized measured 28 wide. The tire was printed with 70028. At least it looked and felt good on the bike stand.

The Continental 4000 is lightweight, smooth running, flat resistant. I run them on both my main bike and my rain bike.

Unfortunately I bought four of these, they were on sale, had good reviews, I 've had success with Conti's in the past.

First tire (on the rear) made it through a century , and about another 150 or so total training miles. I flatted at the very end of the ride, right by my truck, so no biggie took it home and changed it there.

After the normal routine of looking for the object that caused the flat, running finger through tire and wheel nothing was obvious. Put another tube in started pumping, I see sliver of tube coming out of small slit at the seam of the tire casing. Very small opening in tire it was beginning to separate. Although disappointed at the failure on such low mileage figured it just was bad luck.

Put on the other tire I had, less than 50 miles, on freshly paved trail, instant flat. Initially could not see the cause, upon closer inspection, yup, separating on the sidewall again.

Never again, fortunately didn't get hurt as both times it was rear tire.

summary states fast rolling light wt. using Vittoria Latex Tubes. grip on dry road great but not tested on wet roads as yet.

A lightweight tire, good road feel, great traction wet or dry, awesome puncture resistance. The reflective strip in the sidewall really helps at night. Continental a German reliable brand that's been in business for a while and has the know how. My go to tire for a while now ....
