ContinentalGrand Prix 4-Season Road Tire(Return to Product Page)

I've had a very good experience with the Continental Grand Prix 4-Season Road Tires I have purchased. Long life, ease of replacing, and good value

Very responsive and durable tire.

These have got to be the hardest tire ever to get on a rim. I unfortunately did not learn my lesson after I pinched 3 tubes trying to get these on DT Swiss 1800 rims. I left this tire out in the sun, used soapy water to try and get this to slip over the rim. On the 5th tube, I finally got it on without pinching the tube. Aired it up and it is so out of round, like it is bulging to one side. Spinning it, it looks like a zig-zag pattern and not straight at all. Worst experience ever for a tire and it doesn't even have any pavement time, Returning

I use the Continental Grand Prix 4-Season with Vectran for all-around training on the road. They are virtually problem free, and are more likely to simply wear out than to puncture. I typically get over 5K miles on the rear wheel, and considerably more on the front. They also roll well, and work just fine for training races.

Today I had the the rear tire tread split by a sharp rock on a logging road paved with golf ball sized rocks. When I guesstimated the wear on this GP 4, I realized it had close to 4000 miles :) I immediately ordered a replacement of this great tire!

Great tire for the average amateur road cyclist, very few flats, but still very fast and good feel.

I commute year-round (18.5 miles each way over varying road surface including several miles of unswept shoulder with glass, debris, gravel, and dead critters). I've been using Vittoria Rubino Pro for my commute but after several flats (wire shards and glass) decided to go tougher during the winter.

I read lots of reviews, but my experience with this tire on our tandem has been fine. I decided to try a 25mm rear, 23 mm front.

Since the majority of my riding is now in the dark (curse you Ben Franklin!), I usually can't spot debris until it's too late. No matter - these tires just roll on through.

I have 500 miles on the pair and there is no visible wear yet. I run them at 90 PSI each. I'm not chasing KOMs this time of year but I haven't noticed any slowing due to tires.

These are excellent commuter-trainer tires. I can highly recommend.

If you ride on a road with lots of radial wire, glass, and rocks, this is the best tire you can use. great puncture resistance and great sidewall protection, so much better than the 5000 tires that have very weak sidewall protection and wear resistance is also very good

Only put around 125 miles on them so far but they have been as good as everybody has said they'd be. I'm a bigger guy 6'2 230 and the roads where I live are sometimes horrid and rough chip and seal. These tires ride well, roll very well and feel great.

Great tire, pretty much no flats.

I use these tires to train on the roads near West Palm Beach, FL. Great bike lanes, but they're full of glass. These tires seem impervious to slashing. I've worn two sets of them down to the cords which is always satisfying for me. I've rarely been able to wear tires out as most have been destroyed in some other manner. They're only slightly slower than the Conti 4000s I use on club rides. I prefer the ride of the 4 season as it seems less bouncy than the 4000.

Used on my road bike and average 1 to 2 hundred miles per week.

I have ridden on these tires for 10 years and loved them. It seems that they have made them smaller in diameter in the last year or so and now they are nearly impossible to put on a 700c rim. I bought a pair last year from an overseas website and when I got the tires, they seemed a lot smaller in diameter than the ones I purchased from American dealers, including Biketiresdirect.com. I figured they were smaller because a lot of European products are sized smaller than American products. So I just bought a pair of these tires (Conti 4-seasons) from a local bike shop and I'm having the same problem with getting them on the rims. The rims are the same, they're my Mavic Ksyrium Elites that I have ridden for years and they have not gotten bigger, so the tires must have gotten smaller somehow. I have tried all the tricks I have read about online and nothing works, so I'll probably have to take them to the bike shop to have them professionally mounted. I'll be damned if I buy these again in the future. Continental, you have lost a customer because you seem to have tried to improve a product that was already perfect. When you learn to leave well enough alone?!?

Replaced the 25s with the 28mm. The new 28mm compared to the old 25mm still mounted on the rear wheel didn't look any wider. Double checked the box. Double checked the tire imprint. All noted 28mm. Broke out the calipers. The 25mm were within a fraction of a mm of 25. The 28mm are 26.5mm at max width with no load. Bit taller tire. Maybe with load they squish down to 28mm wide. If not, basically replaced the 25s with 26mm tires. If so and if in need for wider than 25mm, it's probably better to jump from 25 to 32mm.

Anyone know what standards Conti uses to measure the width of their tires?

They have me confused. Sprinter 250s, very old tire mounted sitting on the roller bike is 23.5mm, newer model measures 22mm. Now the discrepancies between the noted and actual size of these tires.

Rise the back roads in the valley southeast of Phoenix where if it grows it has thorns. These tires are very resistant to puncture with the exception of the side wall. Combined with Stans they are ideal for riding with less concern about flatting. I have put over 700 miles on them and they seem to be quite wear resistant. I find them to also be quite comfortable on roads that are less than smooth.

I wanted a tire for winter road conditions and I was willing to trade off some speed for toughness and durability. But not this much. These have to be the slowest tires I've ever used, and I've tried many. If you're a commuter and you go along at 8-10 miles an hour and care exclusively about grip and longevity these may work for you, but there are still better and less expensive choices out there.

Completely unsuitable for any type of fast riding or training, too expensive vs the competition for commuter tires. Just don't see any use for these.

I have never suffered a flat tire yet! I have been using these tires for many years now and they are by far the best training tire. They do seem to have more rolling resistance than other race tires. However, every time I ride over glass accidentally and don't suffer a flat, I remember why I use them.

At 250 pounds this is a fast tire that holds up well. I have had no real issues with these other than a sidewall blow out that might have been a foreign object.
