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.
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 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.
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?
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.
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 Conti Grand Prix 4-season tires to replace Panaracers in a 700cx32mm size. I really liked the Panaracers, but wanted something more durable. I was concerned that the Grand Prix would be too harsh, but my concern was unfounded. The may not be as cushy as the soft sidewall Panaracers, but they arent bad at all, and the Conti duraskin sidewall seems tough. Traction is better than expected in loose stuff and dry cornering. They have about 400 miles on them, and tread wear seems good so far.
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!
Love these tires for their durability, traction, and puncture resistance. Just had to replace the rear tire after about 2,000mi but the front is still holding strong. I'll continue to buy these for the foreseeable future.
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.
