ContinentalGrand Prix 4-Season Road Tire(Return to Product Page)

Ride year round on these tires as they roll great, very durable, and I rarely get a flat. Worth the extra $ as they last longer and I change fewer tires/tubes

Much faster and better road feel than I thought. I got a 28mm for the rear and 25mm front...running 80 psi and am enjoying the comfy ride. Not that as much difference between the regular Grand Prix that I usually ride on. Don't forget a larger tube for the 28mm if you don't usually ride that size.

Nice ride, fast, and ideal for long daily commute in all weather (mostly wet) here in Seattle.

Durable, reliable, good rolling Tire

Can't recommend these tires enough if you're looking for long-lasting puncture protection. I've been riding sets for years now and won't ride with anything else on my road bike.

Been riding for past year. No flats and as fast as my Conti 4000s tires.

Black chili rubber is grippy and confidence inspiring in rainy conditions, and is great in the dry too. Have these tires on my race bike and I keep them on for both training and races.

The 25c wide version I use is only a few grams more than the 23c, but it's a great trade off as the 25c is wonderful for confidence on the descents and rough roads.

After 6000 miles, the rear tire had a bit of a flat center section, but the front tire was still round with no flat center section. After that many miles, you'll likely have a few cuts, and I think I had 1 or 2 cuts on each tire, a few mm long. Not a big deal, and the cuts had been there for the last 2000 miles or so with no issues by the time I moved the tires to trainer duty.

I just bought a brand new pair of 25c 4 Seasons and plan on getting another 6k miles out of them. By far my favorite road tire. Did I say no flats in all of those 6000 miles? Yes, it's completely amazing.

Have been getting the GP 4000s for quite some time. Decided to get these for the winter. Another winner from Continental, the best brand in bike tires. Every other brand I get quick flats and the traction is iffy at best. Continental continues to deliver a tire that is relatively flat resistant and corners well. A winner.

Been using this tire for a few years in various sizes, 700X25 and 28 for general riding in my zone which is inner mountain paved and gravel roads of the Trinity National Forest. this tire handles all conditions, winter and summer with ease and when in new or newish condition, gives me the best flat and side wall protection in a light weight tire that I have ever gotten. To me, this tires downsides are that it wears fairly quickly on the rear and near the end of it's tread life tends to be more flat prone. Also it is not true to the size listed, being somewhat smaller than advertized in both the 25's and 28's. The GP 4 season does not handle quite as well as the 4000 series but it is way more capable on rough pavement and gravel. I'm sticking with this tire.

These are the best tires ever. The last tires that I had were the same model and had over 3000 miles on. I put new ones on because I was going on a big ride, but kept the ones I took off. I would not buy any other and I ride in the northwest, rain, bad roads, ice. Have never had a flat.

Perfect traction and weight for racing. Easy to install too.

There isn't much to dislike with this tire. Where I live, the winters are cold and the roads tend to stay wet in the areas where snow melts and runs across them so the GP 4 season's tread compounds and supple case give me more confidence in corners in those cold and wet conditions. The flat protection works great as I get very very few flats. Rocks are a big issue on our forest roads all year and with the side wall protection these tires have, I don't get any flats or blowouts from rock cuts. I ride all year through and have been doing so for the past 28 years and I'm not buying these to be following someone else' idea of a good tire. I have tried many others and the Conti 700x25 GP 4 Season is worth sticking with. I rate this tire at the top of any list.

I use these tires for commuting on my rain bike and for longer rides on my dry bikes

This is my go-to tire during the rainy season in Northern CA. Around here we have lots of hills with grades exceeding 10%, sometimes exceeding 15%. On wet climbs where a normal tire would slip when you're out of the saddle, these hold their grip. They perform comparably to GP4000's, with a barely noticeable compromise in weight and rolling resistance. My one compliant about Conti's is weak sidewalls, in the past year (4,100 miles of riding) I've had 2 sidewall blowouts with Conti tires, one with this model and one with a GP4000. However, that's offset by the fact that I've only had a single puncture during that time, vs. the 5 to 10 per year I would experience with Michelin Pro Race tires.

These tires are expensive, there's no two ways about it. On the other hand, I haven't encountered a tire with a better road feel on Portland's roads, which are, this time of year, usually coated by rain. Less harsh than Gatorskins, less wooden than the excellent Ribmos, and more robust than your usual nice slick.

I've also had no problems with excessive flatting (which I've heard other people complain about with these tires), and Portland's street-cleaning budget has been slashed for the past year.

Good value? Depends on what you want from a tire, but I'm happy with the purchase.

(For reference, I do a regular 10-12 mile a day commute, and some recreational riding on the weekends-these tires get a decent amount of use.)

I really enjoy this tire in a 28. It improves my overall ride quality since most of my rides are long endurance type. Provides confidence in the long fast descents also.

I've been riding on this tire for about seven years. While not the fastest or lightest tire available, it cannot be beat for wet weather traction and it seems to be just about impervious to flats. I commuted daily about 25 miles in rain or shine and this tire has never let me down. A little pricey but worth it if you just want to ride and ride and don't want to have the hassle of fixing a flat while you're on your way to work or back home. I'm 260 pounds and I get decent mileage out of these as well. Worth the money for sure!

Great tire - never a flat

This tire is great because it rarely flats, is tough, will last for a lot of miles (I weigh 170, and usually I get around 2000 miles out of them - that's when the main part is pretty flattened. Probably could get more miles, but then I just use them for the trainer after that). I always buy these tires - they are the best I've used yet! Rolling resistance seems good, and they do great in the wet! I ride these all year.

I have been using Conti GP's on our tandem for years. They have been a consistently good tire for traction and the later models have better longevity
