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

As the locals say if it lives here in Arizona it either has fangs or thorns. Landscapers leave quite a bit of debris on the roads and ultrafine thorns can flatten most tires. We don't have 4 seasons but the Vectran layer has kept me rolling with relatively few problems. I felt the difference in ride with my first pair when I switched out the factory rubber on my Roubaix and they grip well cornering even on the rare day when the roads are wet.

Use this tire on my trek road bike. They last for lots of miles and have excellent flat protection.

Ideal winter tires - when these were new, I locked-up the back brake and skidded the back wheel and thought I must have scrubbed the tire badly, but there wasn't even a scuff on the tire surface. This would usually imply a tire with poor grip, but that isn't the case for these Continental tires - they grip well wet or dry.

use these all the time

No tire that rolls well and provides an acceptable ride is puncture proof. This tire has enough rubber that it will handle riding over road crap that isn't pointed or sharp enough to cut through the tire. If you want to bank the odds further in favor of handling sharp pointed nails, glass, etc., go for a tire like the Top Contact. You then trade a smooth roll for the extra rubber that can handle bigger glass and small staples or nails. If you are willing to accept some road cuts in favor of speed, go for the Grand Prix 4000s. Still durable, but faster. I ride on the Grand Prix 4 Season 23, 25, 28 and 32. I love the 32's. At that size, there is enough rubber to handle Winter in the Northwest. Nonetheless, when you ride over that sharp piece of glass that cuts through your new tire turning it into a throw-away, it hurts. Good alternatives I use are Schwalbe Marathon Supreme and Panaracer Pasela or T-Serv. They also have their trade-off characteristics. The GP4 Season is a huge favorite of mine.

In-city commuter, utility, and light recreational rider, overall about 50 miles per week. Replaced a worn-out pair of Gatorskins (6000 miles with 1 flat in 3 years!!) with these and immediately noticed the lighter weight and more responsive road feel. I agree with another reviewer that the Grand Prixs are easier to mount on the wheel then Gatorskins - I was able to mount one with a bit of muscle on a Salsa Delgado rim, and the other on a Mavic A319 after warming up the tire briefly in the sun. The Gatorskins required me to use tire levers every time. A bit pricey but shaping up to be worth every penny.

Going on 10 years without a flat

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

I ordered these tires as backup to the identical tires I've been using on my two road bikes. They are super. So far - resilient, long lasting and having good grip on the road. And the purchase experience with Biketiresdirect was superb.

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.

I've been using variations of the Continental Grand Prix tire for 30 years. I've used them, not so much because of the ride quality, which is fine, but the flat resistant durability has been outstanding. This new Continental Grand Prix 4-Season edition holds up well riding the rough farm roads in my area while still light weight.

I've used Continental tires for approximately 30 yrs. I started using the Grand Prix 4-Season road tire when it first became available and, as with other Continental tires, I have very few flats, the ride is great and I get about 5,000 miles per tire, barring any flats. I only buy the tires at BikeTiresDirect because the prices are always reasonable.

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.
