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

I've used Continental road tires for years. I bought these to use on my gravel bike on a rails-to-trails path, which was a mix of crushed limestone and packed dirt. They were excellent. Plenty wide enough, but lightweight and easy rolling. And the puncture resistance proved effective, as I did not have any flats during the course of the 66-mile journey. And I'm still using them on recreational paths, both paved and gravel.

Been using the 4-Season for many years. They are durable, light, supple, and overall comfortable. Very puncture resistant. With the new 700 x 32 size I was able to bump up one of my bikes to be more "gravel friendly". Highly recommend the 4-Season.

Long wearing endurance tire used to ride 4K miles across USA (only 1 flat repair'after > 125 miles on crushed rock gravel and washboard).

I put two new pairs of 28mm GP 4 Season tires on our bike's to stop the flats. My wife has ridden 2981 miles on her tires and she has had just one flat. It used to be you would average (on a NEW tire) about a flat for every 1000 miles you would ride (the flats would increase with the miles on the tire). My original GP4 rear tire lasted 4814 miles with 2 flats - one was a seam leak in the tube (that's not the tire's fault) and the other one was caused by a very tiny thorn which was losing about 15 lbs of air a day. I did get all the use I could out of that tire because you could see a few little places of the white cords under the tire's flat center tread before I changed it out.

I do not rotate my tires because years ago a racer told me if you blow out the front tire you are going to go down - if it is the rear tire you can still have control and ride 'er down to a stop so always put your best tire on the front axle. So I always move the used front tire to the rear wheel and put the new tire on the front. That original front tire that went to the rear position now has two tiny places in the worn flat center that are starting to show the white cord below. That tire is about due to be replaced so I will mount the front tire on the rear wheel and put a new tire on the front wheel.

The GP4 is a directional tire -- look for the rounded D's (with the cross hatches) on the outer edge of the tread butting up to the Vectran sidewall belts. The 14 short straight side of the cross hatched slanted D's should be facing toward the FRONT of the bicycle when the tire is correctly mounted.

That original tire that is now on the back has 8358 miles on it and it has had just those two flats I mentioned earlier. Today the front tire that will eventually go to the back has 3550 miles on it with no flats and the molded center line on that tire is still just visible. Most of our riding is on chip & seal, asphalt pavement but we also will get on chat, gravel and dirt lanes, too. I ride year round so I have ridden in the snow and ice down to 5 - 10 F. At those low temperatures about an hour or so is all I want. The GP 4 Season tires are superior in wet & the wetcold environments - just gear down and always keep a bike very vertical when it is very slick out.

After EACH ride we wipe the tires tread completely down with a cloth - this pulls all the junk out of the tread. You don't get very many sharp slivers that stick in the GP4 tread, unlike many other tires with softer compounds. I weigh about 190 lbs, my wife about 135. I believe this is the best pressure for ride, handling, wear & flat resistance on the 28MM tire. On both bicycles I pump the pressure up to 6 bars (87 lbs) in the rear tire and 5 lbs less in the front tire on both bikes. I loose 5 lbs of this pressure when I remove the air chuck from the tire stem. How much pressure does your chuck loose when you remove it? Have you ever checked that? So I am running 82 psi in the rear & 77 psi in the front tire. I could & should probably run a LITTLE less pressure in my wife's tires since she is 45 lbs lighter but I just haven't done the math yet. You know - you will get a better ride but with more rolling resistance. Just like life is, it has been said you have to give up something to get something Well isn't that the truth!!!

We have ridden about every ride here in the KC Mo area with the KC Bicycle Club. Rides that were all in the city, uptown downtown with glass, grates, railroad tracks, sand & everything else those city streets have for us. And the club rides out in all the surrounding countryside with gravel, thorns, cow piles, sand & chasing dogs - you know, those rural areas. This tire just simply takes everything on while you

Im a gravel cyclist for the most part, but I do a fair bit of training on the road, so I went in search a good compromise tire that handled well on road as well as some gravel, I decided to try these. And they did not disappoint!

Ive put these tires through ringer. Everything from smooth tarmac, rough gravel, sand, and some forest service roads that dont look like theyve been touched since the days of wagon trains. As to be expected, they lost traction in sand and really dusty gravel roads as well as areas of mud. But I knew that they would when I purchased them. My main concern was durability. And they went with me in places that would probably be better suited to at least a hardtail mountain bike. Not once did I ever get a flat, tear, or anything of the sort. Ive been incredibly surprised by the amount of abuse these tires could handle.

Just FYI, I ran the 32c with 50 psi front and 55 psi back.

If anybody is looking for a good all-rounder tire that they can count on, I couldnt recommend these enough!

This tire is excellent for winter training and dodgy roads especially for those training rides in the dark when you don't know what you might run over. It's no racing tire, but it's not sluggish, either. Excellent flat resistance. And it comes in a variety of sizes.

I love my GP 4000 Sii tires and have been using them for several years. I got these 4-Season ones for my fall thru spring riding, as that seems to be their intended use. I also went up to 28s for these and although they don't measure much more than my 25s when installed, I have run them with slightly lower pressures and the ride has felt very nice. While these are supposed to be tougher, I have to say that I've never had a puncture on any of my Grand Prix tires. I have however damaged them right down to the breaker before and I'm hoping this winter compound will be just a little more robust. After the snow has stopped and the PA roads have been cleaned up, I will switch back to the 4000 Sii. But for those days where I can get away from the indoor trainer during the off-season, these seem to be great choice of tire. The ride is very nice and the grip is excellent.

What can I say... these are good tires. Most of my friends use Conti's and swear by them. For me this is only second time I purchased these and I don't think I will again. I live and ride in and around NYC and within 2 weeks of popping these on I had a flat. Ok so everyone gets flats. True. However.... I have used Schwalbe's for most of my riding life (past 4 yrs or so) and I can tell you ... I RARELY, if ever, get flats. In fact I can't even remember the last one. I've ridden over 3000 miles this summer without even a whisper of a leak. The only reason I purchased the Conti was because I was about to ride my 4th or maybe 5th Century and noticed my tire had some cuts. So I thought better safe than sorry. Anyway....I've been riding Durano tires for the past 2 years with thousands of miles on them. The rolling resistance is very good, though maybe not quite as good as the Conti's but very close. So Conti users .. more power to you... I'll stick with my Schwalbe's anytime.

I'm happy with these after switching over from Gatorskin. Obviously some durability is sacrificed in that switch, but these still feel substantial and less sluggish.

Only had a few dry rides on these, but road use is great and smooth. Needed replacements for the stock tires on my 10 year old used bike purchase. Easy to mount using a couple tire levers (not my first rodeo however). Bought for the extra protection after getting almost a flat per ride on my other bike.

I've ridden Gand Prix 4-season tires for years. When you are cruising down Berthoud Pass in CO at 40+ mph why would you want to trust your life to anything less. Worth every penny. Happy riding if you choose to use them on your next trip across town or down a mountain pass.

650 miles a week on roads, long lasting for 6 months (with some life left if willing to take risks)

I know these are highly reviewed, but I want to chime in. The day before my Reach the Beach ride (104 mi), I had a flat on one of my Specialized Roubaix (all winter, no problems). On close inspection, both tires were slashed up bad and chock full of imbedded shards of glass (so much I could have started my own recycling center!). In a panic, I ran over to my LBS, and they convinced me to get the 4 Seasons. Got them home, and couldn't mount them on my Shimano rims. Back to the LBS. Mounted, the ride was awesome. I have over 800 miles on them now, virtually all in and around Portland (which should now change its nickname from City of Roses to City of Broken Glass). There is not one scratch on them! Even the rear tire still has the seam running around the center! My only complaints so difficult to mount, and really hard, and I run them at 90 PSI. But if I don't have to fix a flat, who cares! Awesome tires!

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.

I have the 700x28 mounted on Spinergy Stealth wheels on my tandem. They measured at 27.5mm soon after mounting. I wanted something just a little faster than Gatorskins without giving up too much reliability and puncture protection as handling the big bike on a flat tire can be a little bit dicey. I weighed both tires using a hanging scale and they both weighed exactly the same which I took as a sign of quality manufacturing.

I bought these because I really like the performance of the GP-4000 Continental tires and on the other side of the coin I appreciate the puncture resistance of the Gatorskin tires. So far so good. Yes, not quite as fast as the GP-4000 but for sure livelier than the Gatorskins. For sure faster than the Gators and so far no flats so we'll see how that works out longer term. I bought these for ultra distance timed events (double centuries) where speed is important but flat resistance maybe more so.

My previous set of Grand Prix 4-Season lasted a little over 4000 miles. Had one rear puncture in 4k is awesome! One thing i really like about them is the ride. Usually when you have a tire that is this puncture resistant they will have a harsh ride. These are great tires for the money.

You'd be hard pressed to find a more durable and better performing tire in the sub 250g weight range.

Well wearing,smooth rolling and fast. Best tires ever

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.
