Continental Grand Prix 4000?

Is anyone riding these? I'm just about to order a Pair but I thought I'd ask here first....

Thanks in advance!

I'm riding them, plus a couple of friends. No punctures, great grip, highly recommend.

Thanks!!

A lot of people in these forums like the GP4000s. That's why I bought them about seven months ago. But I must say I have never liked them to the degree others here have. Primarily for three reasons:

1. Flats - These tires are supposed to be bomb-proof because of the hard shell kevlar lining thing but I got about 5 flats on the rear and one on the front over the course of about 1800 miles. You can definitely feel the difference in the construction of the tire but I was still getting flats. Maybe that's not a lot of flats but still...

2. Ride quality - The first ride on these tires I almost lost it in a corner on a fast decent. The bike started to squirm and fishtail. I tried to convince myself it was the frame and not the tires because I had just dropped $55 per on these sweet tires. But it was for sure the tires because I had never felt that squirmyness cornering on my Specialized pro tires. It wasn't like this all the time. The bike felt fine for the most part. It was just hard braking in a corner which was scary.

3. Sidewall issues - The sidewalls wear out on these tires quickly, but I have heard this is just the way it is with tires that provide such a good ride. I have a big lump on the rear GP4000 sidewall so I just bought a Hutchinson to see how that tire is.

All in all it's a decent tire, just not all it's cracked up to be IMO. But don't let my feelings negate all the positive comments about them.

I did. Two times. The second ride I got a huge hole in the sidewall. A friend had four punctures in a week. I haven't checked with him if he inspected the tire so maybe the last three was his own fault? Anyway his LBS told him they were crap. But on the other hand there seems to be a lot of people saying they are good.

Now I'm back to Mich pro race. I don't really know how the grip compares to the GP 4000, but puncture resistance seems great, never heard a bad word about them. Also the rolling resistance is much lower than for the GP 4000.

Approx 50% of my club using 4000's, 25% using pro2race (including me) and 25% for the rest.

GP3000s had vulnerable side walls. Does not look like anything has changed.

Yep, great tire. Have been using all this past season with just under 5,000 kms. Good wear, great durability, good if you get caught in a bit or wet weather.

I switched after a couple of seasons on the Conti Attack tires. Little bit cheaper & just as good.

The older GP 3000 tires had great reviews. GP 4000 is only better.

I am well over 2000 miles on my GP 4000's and no flats or problems yet. I would definitely buy them again.

Thanks J, I appreciate all your comments, after all, that's why I was asking...it's nice to hear good and bad...

Just to let you know, my Six13 came with Hutches, they were a good very lightweight Tire...they jus wore out sooo fast obviously...plus I got tons of punctures...but there you go, lightweight performance and hard wearing puncture proof just don't go together in one Tire...

Thanks again!

Thanks J, sounds like you had bad luck with them then...

I'm currently running Miches...they've been bullet proof, megamium 2's actually, the only drawback is they're heavy...I just got tired of punctures so I bought them just before my last century and left them on...I must have seen 40+ riders at the side of the road fixing flats, some riders I was talking to afterwards had two or three...maybe I was just lucky??
