I run or have run various conti tires and tried these for first time. After three years mounted (not heavy miles) they have developed splits/cracks all around the circumference of the tread of the tire (plus the usual deterioration of the threads around the sidewall you get with all contis). But none of my other contis have ever developed the cracks. Still riding on them but it looks like the tread is all coming apart. For comparison I have a set of Conti Grand Prix on another bike which are original tires and over seven years old with none of this happening. Would not buy this particular type again and after the blow-off I got from conti consumer support when I brought this to their attention I am rethinking the brand in general.
I have been using them on my trek road bike for years. I average less than one flat per year (I ride 5,000+ each year). Expensive tires but they last. My 32 mm tires will last over 5000 miles.
I have used the Vittoria Corsa G2.0 tire in my long ride for a long time.
However the recent ride, I had several experiences with the flat tire in my recent ride.
When I checked the tire after riding, I could see many stone and glass chips nailed to the tire surface, and removing them was a sort of headache and I was worried about the flat again.
Finally, I purchased the Grand Prix 4-season clincher and it was quite impressive because I haven'
t had a flat tire during my 200km and 300km ride even I rarely saw chips on the tire.
I am not sure about grip on wet surfaces, but I am pretty confident on the dry pavement.
If you are worried about a flat during the long ride, I strongly recommend this tire for you.
I have run the GP 4 Season tires for over 20 years with great results. Good reliable handling, few flats and very good durability. Never considered switching tires with the performance I have had from these. Highly recommend.
The only tire for any season!!
I've ridden the 4-Season about 15000 miles over the past decade. This tire has good grip and a terrific feel for the road. No tire is flat proof, but this is very flat resistant. Easy to change due to kevlar beads. Average wear.
When the rains start and the roads fill with debris, these tires go on and the GP 5000s come off. I think this tire is a good compromise between the GP 5000s and the Gaterskins in terms of rolling resistance and puncture protection. I've only gotten one puncture in these in over 2 years, although it was a sizable nail that no tire would have survived.
My one gripe with the GP 4-Season is the sizing. I have very tight tolerance with my Ridley Noah and a 25mm tire measures nearly 27mm at 105psi. I can run 25mm with the GP 5000s, but have to run 23mm with these. Very annoying!
Quality, Quality, Quality...ride could be softer, but ? After a 20- 40 mile ride in Florida 95 degree heat, I rely on Conti durability to get me home to several Kool Ones...
The Continental Grand Prix 4-Season tire is my go-to winter tire for the mild winters of California. The GP 5000s come off the bike in January and go back on in April or May. The GP 4-Seasons are not as supple, obviously, but they have good rolling resistance and puncture protection is superb. These tires handle gritty chip/seal roads with winter storm debris, twigs, small branches, small stones, etc., without concern. My BIGGEST complaint by far is the sizing! A 25mm tire actually measures 26.8mm at 7 bar and rubs on my Ridley Noah frame. I have to run a 23mm version on the rear which rides harder.
I�ve run the 4-Season 25mm tires for years with a lot of success. After reading a lot about the advantages of a wider tire and lower pressure I decided to give it a try. The 32mm won�t fit on my bike but the 28mm do and provide a stable and comfortable ride with no noticeable difference in speed or effort.
I weighed these on my digital scale. I weighed several, I think I had 4. Then weighed Conti 5,000�s AND my Gator skins.
These tires weighed more than my gator skins.
About 340 grams on average. About 100 grams more than my Conti 5000s.
So VERY HEAVY. NOT. A racing or light weight tire as I expected.
I bought 3 of these. They weight much more than advertised. The ones I got, I weighted on my digital scale, They weigh more than my gator skins.
For A 28 tire, about 330 grams. VERY heavy.
I currently have the Continental GP 4-Season tires in both my bikes (700x25 and 700x28 sized) so you can say I really like them. I bought the 4-Season because I prefer the extra protection vs their normal racing ones, however the 4-Season tires are fast tires too. They are light, great traction and have not had any issues with them (only had 250-300 mi on them). I was riding Schwalbe One DD before, and I can say that Continental GP 4-Season seem to provide a smoother ride with better rolling resistance.
I am a daily rider, 20 to 30 miles. I have been using Conti GP 4-season's for years. Fronts last me 12000 to 15000 miles, rears 8000 to 9000 miles. There is not a thing I don't like about them.
This is a Bulletproof good riding tire. I use them year round including my rain bike. Its been the tire of choice for 5 years now.
I like these tires very much. They were suggested to me by a fellow biker, and I have used them exclusively ever since. Easy to mount on my wheels
The only tire I use on all 3 of my road bikes. The best flat protection by far, great road grip in any condition and still a a soft enough ride w the 32m tires.
Beware of size change without spec change 2018
My road bike's brakes used to fit 28mm Continental Grand Prix 4 Season Road Bike Tires, now they don't. Seems Continental changed the size of the tires without changing the numbers or names or actually telling anyone. If your framebrakes used to barely fit the 28 size, the new revision will be too big.
How to tell the difference
Older 28c is embossed MAX. INFLATE TO 116 PSI - 8.0 BAR
Newer 28c has MAX LUFTDRUCKINFLATION 8.5 BAR - 115 PSI.
Flattened out bead to bead dimension of the newer 700x28c version has increased by 5mm. That extra 5mm of perimeter is enough to make them intermittently rub on SRAM Red caliper brakes on recent Bianchi carbon frame.
I use the Conti 4 Season Grand Prix on my weather bike - the one I ride when it is raining or just wet out. These tires grip the road in wet conditions, and they are tough enough with the Vectran to handle the extra grit that gets on everything in wet weather. We have an extremely hard quartz in our area, and this stuff is used everywhere on the roads. It is loose on the surface of paved roads, and sharp bits are embedded in the tar. The Grand Prix 4-season tires don't slice, tear, or puncture very easily so they are working out perfectly for me.
I bought the 28mm 4season to replace 4 year old 28mm Gatorskins. The Gators lasted over 10000 miles and still look usable. My bike shop said the rear tire looked thin. I put the 4 seasons on, noticed that the back tire was hitting the frame, made sure it was on right, still hitting. Took it down from 115psi to 80psi and it just barely gets through. Im still going to use them and hope that a little wear gives more clearance so I can pump my tires up! I give it a 3 because it is larger than 28mm, which is the max size for my domane. The gators had plenty of clearance even when brand new. Why the size difference, conti?
