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.
Replaced Gatorskins with Four Seasons. My Vigorelli came with 25mm slicks, upgraded to the 28mm Gatorskins. Ran the Gatorskins for 5600 miles. Bought 28mm Four Seasons, but the rear tire was too large for the rear brake housing on Shimano 105s. Western Bike Works exchanged them for 25mm. Pumped up to 100 psi, the tire width is 26.51mm, measured with electronic caliper. Perfect tire for how I ride. Love them. My training rides are 40 miles, over Houston streets, then concrete bike lanes along the bayous. Club rides 30 - 50 miles long.
I run 28s on both my winter training gravel bike (CX) as well as a tandem. I've ridden on all kinds of gravel roads and even on a few MTB trails with them. On the tandem we've recorded descending speeds of over 60mph and find them totally trustworthy. Logically, they are slightly heavy, but otherwise great handling, super durable, and hard wearing. My go-to tire.
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.
I use the Grand Prix 4-Season on both my road racing bike and my commute bike, it handles well, and offers more puncture protection than a race tire. These are great tires, rain or shine, which is especially good for those long winter months (here in Portland, OR, anyway). If you find yourself faced with snow in winter, a studded winter tire is more up your alley.
Bottom line, this tire handles nearly as well in rain as it does on dry ground. It's a great purchase for anyone who rides in all conditions, and wants a durable tire that feels good.
Like many other reviewers I am a big fan of these tires. The only improvement I'd like Conti to make is to go one size wider. If I could I'd ride a 28 on the front and one size wider in the rear during the winter months when I'm commuting in the dark.
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?
All around rider of top-line equipment, I appreciate the durability and QC of all Contiï¿½s. Ride quality is superb. I still prefer smaller 23/25c tires for my road riding, but I donï¿½t hesitate to use these on the many dirt/gravel/rail sections which are parts of my usual loops.
My new(er) bike's tires were pretty tired. I DO NOT want a flat because I pushed the life of the tires that came on the bike. The Cont. Grand Prix are tight on the corners and smooth on the straightaways. Mine are 28mm because I'm a serious recreational rider.
I'm a one-bike guy so I need tires that allow me to commute in urban areas without constant flats AND keep up on longer road rides. After trying a few different tires, I've found these to best hit that sweet spot. They aren't the lightest, but they also aren't that heavy. I've been very happy with them and riding more confidently without flats since making the switch.
These came highly recommended for my somewhat rough country roads and occasional gravelcaliche segments of rides. Never had a flat on them. They are, however, a noisy tire, more so than Michelin, Vittoria, Hutchinson I have used. Grip was on par with other tires. Good tires but there are equally good tires that do not have the road noise.
Ride about 2,000 miles per year and have used the GP 4-season for 15 years or so. I have had very few flats, probably less than one per year on average. Great traction and handling. Hard to beat this tire at the sale price.
I bought a set of these a couple of years ago for my road training bike. After over 3,000 miles, I've not experienced a flat. Rolling resistance is light, and they hold their grip very well, though they do get a bit sketchy in heavy rain.
I use this tire on road bike. I use it on asphalt surfaces 40 to 80 miles per week. Durable, low rolling resistance, flat free . Tread lasts for over 2000 miles. I am on my 4th or 5th set. I have not found a better road bike tire.
I love Continental tires but was disappointed with the quick wear and constant sidewall cuts I was getting on my 4000s tires. I decided to try the Grand Prix 4 season as a last chance with Continental. I do a LOT of riding and was tired of changing flats. since I switched to the Grand Prix 4 Season, I have not had a single flat. The tires wear like steel (i.e. long tread life!) and are tough. I ride in all conditions, year round in Colorado and regardless of the gravel and debris I encounter, these tires can take it!
Extreme durability, over 10,000 road miles on two different front tires, and usually about 4,000 miles from rear tires. Average about 3,000 miles between flats. And the weight is reasonable as well.
I commute to work and its a good all around tire I would have given it four stars. My only dislike would be the price the only time to buy these tires is when they are on sale.
Top notch tire. Did a spring classic with about 13 of the route on gravel and dirt roads and the tires held up through the whole route. Hit some serious ruts, bumps and potholes and the tire never quit. My buddy and I both rode these tires and neither of us had a problem.
