Continental Grand Prix 4000 = Major Fail

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Continental Grand Prix 4000 = Major Fail

I bought my first pair of these tires after hearing wonderful things from everyone. I had a friend who rode his for over 6K miles.

I have ridden mine for less than 200 miles and started having flats, I didn't pay much attention to it after the first time but it has happened twice since. I took the tire and examined it closely and realized that there was a tear in the side wall. I am very satisfied, I would have expected these tires to beable to take more abuse.

Has anyone experienced this with these tires? And are there any other tire recommendations?

I had those on my Bianchi and rode them for quite a while without incident. I had a few flats but nothing that wouldn't have punctured most tires.

Conti GP or 4000's or 4Seasons are the only tires I will ride. I've had 4 pairs of them over last 6 years and several thousand miles on all of them and never a failure caused by tire. I still use the first set that I bought 6 years ago - I use them on my trianer in the winter and the first few hundred miles outside each year. The trainer can't even wear 'em down.

GP 4K

I just think it might have been my luck. I think I will buy another tire...

I have had nothing but great luck on my GP4000s. Same goes for the girlfriend as well. Perhaps you just had a bit of bad luck.

I've got a set of 4000's on mine, ~800 miles so far, they still look like new, not a single flat with them. Had Maxis Fuse (originals that came on my bike), dang things gave me flats continuously...had patches overlapping patches; I never as happy as the day I put the 4000's on.

Well at least you are satisfied.

Tears can happen to any tire at any time. The tire is not at fault for this one.

I am getting a lot less flats after switching from Krylions to GP 4000S. Flats used to be part of cycling, now it is an occasional thing.

I reckon the GP4000S is more puncture resistant than the colored GP4000.

My 4000S have more than 3000 miles on them, with exactly 0 flats.

GP4000S, as GP4000 with chili compound are indeed more resistant than their colour counterparts.

GP4000 are susceptible to tears in the sidewall. I had a pair that lasted less than 2000km. At the recommendation of a teammate, I now use GP4Season, which roll just as well, weight only a bit more, and are much more resistant (1 flat in about 3000kms; the above mentioned teammate still has thread left after >15000km)

GP4000>Ultra Race>Ultra Sport

My experience has been that GP4000s are much more comfortable than Ultra Race. I ride with 120psi in the rear on a aluminum frame. I have had many flats with Ultra Sports and none with Ultra Race or GP4000s.

For me GP4000s have been great tires.

GP4000S are also vulnerable to lockups. A friend of mine wore his to the threads after locking up his rear wheel. My group of riding buddies don't have a huge amount of experience with different tire brands and models, so I can't say if other tires would have taken it better. Unfortunately, he only had them for a few days before this happened, so I can't comment as for longetivity and puncture/tear resistance from road debris.

I had a sidewall tear at 600 miles after brushing against a galvanized utility box grate/lid, but consider that a "me problem."

I've had only one flat on GP4000s and 4-Seasons, and encounter a fair amount of debris on the road.

In nearly 45 years of riding and racing, I have not ever had a sidewall "fail" on its own. Never. Not clinchers, not tubulars, nothing.

Make sure you are mounting the tires correctly. Pump them up to about 50-60 pounds and check to make sure the bead is set properly.

BTW...I ride 4 seasons on my FG/SS and that's because it gets ridden in bad weather a lot. If it's raining or rain is close, I take it out as it's not an expensive bike and it's easy to clean up. The sticky race tires, when wet will pick up road crud. Never had a problem.

Actually, it sounded as if the flats where the cause of the tear on the sidewall. The rims maybe putting a lot of pressure on the tires one they gone flat. If you have a lot of flats, check your rim tape. You may need to replace that. Also make sure you have proper tire pressure and when installing the tube, nothing is pinched. I only have one puncture flat in 3 years, but I have numerous pinch flats and inside-cuts due to rim tape didn't do a good job at covering the spoke holes.

Good luck.

I think its just bad karma...I put on Conti 4000 w chili and had 3 flats within 200 miles. Switched to Conti 4season and had no flats for 100 miles.

Maybe you would be happier with Gatorskins? There isn't a tire I've used that didn't have a thin sidewall, so I don't understand how you can write off a well respected model like the GP4K over a flaw that most other road tires exhibit. Assuming you didn't damage the sidewall yourself, I'd try and warranty the tire to Continental, otherwise, just boot it and keep riding.
