Continental Grand Prix 4-Season Tire

The Grand Prix 4-Season borrows technology from different tires in the Grand Prix line up to offer the best combination of performance and durability.

The core of the tire is a 3 ply 330tpi Grand Prix 4000 casing. This casing is then completely wrapped with a tight mesh DuraSkin casing. This is the same casing that is used on the GatorSkin series tires. This GatorSkin wrap protects not only the sidewalls, but the entire tire. On the top of the tire casing and under the tread are two layers of Vectran Breaker strips that give excellent puncture protection. The Vectran material is very flexible and pliant, so it does not affect performance of the tire.

The tread is a special carbon formula which is very similar to Conti's venerable Black Chili tread. It has a long life span and great performance as well as excellent adhesion on wet roads and at low temperatures.

All of these elements combined in one product make for one of the best high performance training tires ever produced.

    Yep, I have a set of 28s and over 1000 London commuting miles on have had no flats and only light wear on the rear . I do go round every now and then and dig out small lumps of glass that seem to slice into the rubber but amazingly they don't penetrate the vectran layer . just dig them out and away you go. I agree that you need to keep them up to pressure and a decent set of inner tubes helps in this respect . Great tyres and a worthy investment .

    Pros: handling, resistance to punctures ,weight,quality

    Cons: Price, sidewall in a dirty black colour !

    The 700x28s are about the same width as my Open Pave 700x24s. If you're looking for a true 28, these probably aren't it. I was looking for a "fat" road tire for gravel and winter riding on my cross bike. These tires do appear to be extremely durable, though.

    Pros: Durability

    Cons: Run very narrow

    I ridden this tire for about Five seasons, and this tire holds up well. Sometimes the road turn to potholes, and broken pavement, Glass :( I once ran over a pile of glass and the tire got me home without incident. This tire grips well on wet pavement. I weigh around 180 and have always run Max. air pressure of 125 PSI, I have even ran 130 PSI in the local time trials and the tire has never failed me. I also note, that I run a Contental Grand Prix up front, to get a little more speed with a thinner profile. If you do indoor training there will be some wear, just plan to replace the tire every season and you’ll be happy.

    I purchased 2 sets of these for winter riding 700x23 and 700x25 which I used to replace 2 sets of Michelin Krylions. In cool weather I found the Michelins to be unacceptable as the shoulders gripped so poorly I almost went down several times just riding across small pavement ruts. On with the Continentals. The 700x25 turned the ride on my commuting bike into Lexus smooth and the tire grip on cold, dark, wet mornings was excellent. The 700x23 ride a bit more firmly but have excellent road feel and traction. The ride is far better than the Krylions. When the weather warms and these tires wear down my next tire purchase will continue to be Continentals.

    Continental is simple the best tire, period. Look, if you keep them inflated to the max, or near max you will have no pinch flats, period. You should also be able to ride over varios debris with flatting as well. These guys in here who get two or three flats every month or two are definitely not inflating their tires properly! As far as ride quality, don’t be a pansy -- ride hard and ride long -- and by all means, KEEP THOSE TIRES INFLATED AT LEAST UP TO A POUND OR TWO NEAR THE MAX AND YOU WILL BE FINE -- HENCE, GOOD TO GO!

    My Son had a pair for 3 years. He estimates that they have done 50,000 Kilometers with three punctures. Still using one of the set, the other will need replacing soon. I recently got a pair for my bike. Ridding on Gator Skins I was getting at least two punctures a month. 3 months on and no punctures yet on my set of 4 seansons.

    While I do not disagree with the other reviews in terms of the durability of this tire, I do want to mention that if you are switching from the Michelin Krylion tire, you will notice a significant reduction in ride quality... it’s pretty harsh, thus it warrants a 4 in my opinion (with the Michelin Krylion getting a 5). This is based on tires in this category and "year round" riding conditions in the Washington DC area. It’s also $15 more than the Krylion.

    I have now ridden these tires for 3 years on 3 bikes and have had phenomenal performance out of them. I used to train in the winter on Specialized Armadillos or Conti Gatorskins, but these offer supreme grip and wear, and are practically a race tire. I live in urban and dirty road-Philadelphia and have yet to get a flat from a normal road hazard. I wear out about 3 sets a year. The only one which failed was during an off-road diversion and I tore the sidewall. No complaints there, as I’m 185 and I was on a gravel road covered in babyheads. If you only have cash for one set of tires to race and train on, this should be it. Especially you cash strapped college kids. I wish this tire was around when I was in school!

    Conti’s 4season tires are simply the tuff brute .New York City glass and coblestones, potholes and sidewall damage just can’t hurt them. They have lasted me two hot summers and freezing winters with only minor wear riding hours every day in our concrete canyons.

    As bike tires go, these have amazing durability! I put 4500 miles on my first set. And they’re finally wearing out. That was roughly 10 months of daily commuting for me - in all weathers, mostly on pavement. I did get a few flats from thorns (face it: NO tire is completely thorn-proof!). One dark morning I got a "snakebite" flat on the rear tube when I hit at about 20 mph a poorly-marked saw-hole cut in the concrete. But the tire itself was undamaged! Given that I’ve had a hard time getting more than 1000 miles out of lesser types of tires, the Contie 4-Season’s are worth every penny!

    Wow! I weigh 185-190lbs and I do not want flats or cuts on my tires. The GP4 tires are unbelievably tough and have lived up to the hype. 2000-2300 miles on my set. I only use them on the rear - little signs of wear and I have ridden in both urban and country setting.

    These are great, very puncture resistant but they can be a little harsh compared the Michelin. I’ve ridden on dirt/gravel roads w/ these and haven’t punctured in 5 months. I found glass in one tire and it didn’t puncture the tube!

    These tires are everything that Continental says they are and more. I have a newly discovered confidence with corners when it is rainy and cold. Now I watch other riders crash and flat out of races. How much would you pay to be safe?

    Great tires! I used a 700X25 for 2000 miles as a rear tire this winter and had no flats and no significant cuts. I had had four flats in the previous five days prior to mounting the GP4 Season. Given the conditions that I rode the GP4 Season, I expected to have numerous flats and cuts. I weight about 155 lbs and do not ride much dirt; after 2000 miles the tire had several spots with the cords showing. The sidewalls of the tire showed no damage after 2000 miles. The tire had excellent traction.
