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.
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.
Very durable all weather tires. Best tires I've owned, had Continental 4000, Gatorskins and many more.

Like the 28 more comfortable ride.
Great tire for the average amateur road cyclist, very few flats, but still very fast and good feel.
Usually used Gatorskins. These have a more effective looking tread. Also, with the Gatorskins, I hit something sharp and one of the belts within the tire broke and punctured the tube. Weird.
I've ridden in the rain, occasionally in the high 30s, but no snow. Anyway, so far so good with the 4 Seasons, but it's early.
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.
Comfortable ride for a tire that is so puncture-resistant. I've had a lot of issues with the GP5000s puncturing, but so far never with the GP 4-Season. My go-to for winter riding where changing a tube would be uncomfortable due to cold.
Great traction in our rainy northwest! Smooth ride, responsive turning, and I don't have to worry about those slick spots on the road!
My serious racer friend recommended these tires. I am not racing and I ride 50-100 mile rides. What a difference. Only one draw-back. I hope I will remember how to change a flat.
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.
700x28 went 2500Km down the lenght of the Cascade Mountains on the front wheel without a single flat. The traction is truely amaizing. But most of all I tour with clip-on aero bars and the smoothness of the ride coming up through the fork even on chip and seal road was way better than any tire I have toured with. When ever the 700x32 4-Seasons come in I will be putting one on my rear touring wheel.
I have been commuting and day riding with the 700x25 4s and find it an outstanding tire in Portland's rain and slush.
These are great tires. I have been using Gatorskins for many years and really like their durabilty, but wanted a faster and better handling tire for longer rides. I researched a lot of tires, and I am really happy with the GP 4-Seasons. They are quick, smooth, and grippy. I highly recommend these tires for all-around training and distance rides.
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.
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.
