Review by Starke Raving
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.
Review by Bob Lehman
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.

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.
Review by JoCalvert
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.
Review by FFA rider
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 ....

After a stretch of going through 3 sets of tubeless in less than 3 months, I went back to clinchers and was looking for a decent rolling tire that would give me some puncture protection. Settled in these tires but got a sidewall rip in a tire the first week I had them on. Was riding in south Florida too so it isnt like Im going through potholes. Ok tire but dont know I Id buy again.

My go to road tire for the last 4 years. Smooth durable. Typically last 2000 miles. However, on my new Enve 3.4 SES disc wheels, the tires are very difficult to mount, compared to my Zipp 202s 303s non-disc, which are super easy to get on. I'll be trying some other brands to ease the pain.

CONTI TIRES ARE THE BEST ON THE MARKET
Review by Smatson49
My favorite road tire for a decade. Improved tread material. They have a very supple feel compared to other brands without sacrificing rolling resistance or speed. The roads in our area are the worst. The tires hold up very well to the terrible alligatoring and pot holes. I ride 25mm.

This is the first time using Continental Tires after using Michelin tires and so far they seem fine. The rolling resistance is definitely better without affecting handling. I only have a couple hundred miles on them so far.
Review by armoredveh
It doesn't get any better than these tires...the gum wall sides look really good too. -) I only wish Continental made these for tubeless rims.
