Continental Grand Prix 4-Season Tire

The Grand Prix 4-Season Tire has been a favorite of countless cyclists for the last decade. Continental developed the tire as a more protective, even more durable, version of the venerable Grand Prix 4000. Pro riders were looking for more of an all-season, all-weather tread, along with greater sidewall and flat protection. The rub? These same riders weren't willing to sacrifice much performance or feel in the process. Oh yes, it couldn't be too heavy either. Continental delivered, and though there have been some quiet updates to the rubber compound over the years, the essence of the Grand Prix 4-Season rolls on.

The core of the tire is a 3 ply 330tpi Grand Prix 4000 casing. This supple casing is the same one found on Conti's top performance clinchers. It delivers a uniform feel and ability to react naturally under duress, but it isn't soft. Conti's tires are firmer for a reason. The rubber compound of the outer tread is designed to grip and hold through the shoulder, so tire deformation is designed to be minimal. These long wearing and low rolling resistance compounds are specific to each tire design, and in the center of Grand Prix 4-Season's tread you will see constant center line for fast rolling, as well as large siping zones to shed water and provide grip in loose material. Large center to edge vector-shaped zones with mini-tread lugs fenable maximum cornering grip in all conditions. The tread rubber is thicker in the center, and thins as it wraps the edge, delivering great wear, but not mitigating road feel.

The overarching protection of the tire is provided by DuraSkin technology. DuraSkin is a polymide mesh fiber that wraps the casing from bead to bead, and is designed to protect your it from sidewall abrasion and puncture. While still offering protection in the center of the tire, the primary reason it wraps the entire casing is to provide a consistent feel and offer a more supple cornering edge. Between the DuraSkin wrap and the tread are two layers of Vectran Breaker strips that give maximize puncture protection. The lightweight Vectran multifilament material is very flexible and pliant, and the double layer is Conti's assurance of protection.

We see the Grand Prix 4-Season on tandems, commuting steeds, pro racer's training bikes, and just about everywhere. It is a terrific tire and widely popular. We trust it, and believe you will as well.

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!

The 28s measure at 25mm...


Posted on 7/25/2006 1:04:42 PM

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.


Posted on 6/25/2006 1:37:59 PM

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!


Posted on 4/21/2006 11:15:41 PM

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.
