The Vectran breaker wards off flats but is also supple for less rolling resistance and greater comfort than other puncture resistant barriers. Kevlar beaded folding tire. 430 TPI.

The luxury model.

It's packed with features! The Vectran is tops for preventing flats without ruining your road feel. The Duraskin helps prevent sidewall cuts. The extra soft rubber compound makes the tire grip exceptionally in bad weather. ...and all this without weighing a ton or feeling like a training tire. It's great! But somebody's got to pick up the tab, and it's a bit pricey for a training tire. If you have the means, I highly recommend picking one up.

Great winter tire

Have always had good luck with Continental tires, and I especially like the GP 4-Seasons for my winter bike due to its nice ride quality, excellent grip on wet pavement, and decent flat resistance. The tread compound does seem fairly soft, which is undoubtedly why they grip so well, so they may not last as long as tires with a harder compound - but for me that's a worthwhile trade-off. I'm happy to get 1,500 - 2,000 miles on a set of tires and the GP 4-Seasons will do that easily.

A must for four season riding

These tires provide amazing grip and stability without the sacrafice of speed. I was a little hesistant at first, however, I switched into these from a pair of 4000's and felt nothing but improvement. I commute to work and ride year round in northern NJ. I can't believe I didn't start riding with these sooner.

Solid product, just like most Conti stuff

Easy to mount, rolling resistance is average to good (not spectacular? ). I ride about 60 miles a week over Seattle streets through multiple construction zones and thus far only one flat after 500 miles. To be fair, it was a one-inch jag of glass that cut through all layers, but I would think that with all the ballyhoo about Vectran that this would have been less of an issue. Not quite as tough as the Hardshell, but the ride quality is palpably more smooth. They were on a 40% off sale, so the value at that price point is good, but full retail seems a little high for what is promised to be an almost invisible flat-protection system.

Best tire for the money, especially at the sale price offered at BTD.

Have used many different bike tire brands over that last 40 years, but Conti GP 4-Seasons stand out as one of the best for wear, flat resistance, and value. I ride trails and a lot of county blacktop roads, both of which can at times have a fair share of debris, glass, thorns, etc. I keep in practice changing other people's flats, because I don't get many even though I run them down to the cords over several thousand miles.

My personal favorite road tire

I have tried a variety of tires over the years - Michelin, Vredestein, Vittoria, and several other Conti tires too, but these Grand Prix 4 Season strike the perfect balance between grippiness and durability. I do about 3 rides a week, 20-40 miles., usually in mild dry weather, but often on wet roads. There is often debris ranging from rocks to glass, and these tires are the most resistant to flats of any tire I have ever ridden.

As for mileage, I have squeezed over 3000 miles from them, but that wasn't a good idea. After 2000 -2500 they do start to feel less grippy to the point that even with some decent tread left, it makes more sense to change them. Not unsafe, just less grippy than you'd want.

They are expensive, but if you buy on sale and hold them until you need them, they are not unreasonable.

Ideal balance of durability and grippiness

These are my 'go to tires'. I'm a recreational road rider, doing about 100 miles a week, and find these guys to be very puncture resistant compared to other brands and other tires from Conti. They also have a pretty good supple road feel, but not quite as much as from some more vulnerable tires. I typically ride them about 2500-3000 miles between changes, and have gone as long as 4000. By then the rubber is just too dry to give a god ride. Good in wet or dry conditions.

Buy on sale and they're a fantastic value.

Remarkable combination of grip and wear resistance!

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.

A great compromise - performance, durability and grip.

I moved to Portland riding Michelin ProRace 4 but they flatted too often here.

At first I tried Gatorskins and although bulletproof, they were no fun to ride.

Next I tried the Gran Prix 4 Season. It rode quite well so I put a set on my rain bike too.

Two years later, I'm still a big fan of this tire. In fact I ride them year round.

I started noticing a lot of local riders had discovered them too which confirmed my belief that I'd discovered a great tire.

Excellent tire - especially good in winter

Conti GP 4 Seasons have very reassuring traction on cold, wet pavement, a nice & fairly supple ride, and reasonably good resistance to flats. Not a racing tire, or a commuter tire, but having a blend of characteristics which make them ideal for year-round training, club rides, etc. The tread compound doesn't seem to be especially long wearing - likely a trade off for having such good grip - but I feel comfortable going 1,500 - 2,000 miles before replacing them (and I tend to replace tires sooner than later). They are a little spendy but I prefer running premium tires and BTD has a good price on them. Highly recommended.

Won't ride anything else

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.

Excellent trade-off favoring tough enough for road crap without giving up too much speed

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.

Durable

Have been riding, training and racing on tubular road tires for the past few decades. 1st set of road clinchers since the early 80's. Picked up a set of 25mm for the FGSS bike. Running relatively low psi (85-90psi for my 58kg mass) for the last 2000km over gravel to smooth roads. Tires after 4000km are fine. A bit square and tread worn. Not the high level of performance (cornering, rolling resistance, supple ride, mass) of a high quality tubular. But for my specific use the tire is more than adequate. Liked them enough to purchase a set of 28mm. Sort of enjoy gravel grinding&128539,.

Recommend these tires if in need of a durable, decent performing, easy to mount training or general use tire. Bit pricey off the shelf. A good value considering wear after the number and type of km. put on these tires.

Phenomenal, Reliable Tire

I bought the GP 4-Seasons (28mm) to use on my '92 De Rosa for general riding, which includes solo training rides, club rides and medium touring (rear rack & panniers). I've put 1,000 miles on them since June, with zero flats. Hit a few rain pockets and traction was excellent. Loved them so much, I bought the same set for my Moots, which I just built-up at the end of July. I have 600 miles, with same type of riding (training & touring), and they've been nothing short of perfect.

Noticeable upgrade from Gatorskins

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.

The Best Commuting Tire Available

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.

Love these tires

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.

28mm update

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.

too hard to put on rims

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?!?

great desert tire

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.
