Continental Grand Prix 4 Season Tire - Clincher

I have ridden these tires (28s) for the past 5 years on my road bike in just about any "reasonable" condition, including distance rides, gran fondos, dirt trails, even gravel grinders and "Roubaix". Never, NEVER had one flat or fail. I am a great fan/convert to tubeless, but on my upcoming remote ride to Wyoming, what will I take? Yep, 4 season 28's.

I posted a review a while back and somehow I accidentally deleted it. But the gist of it was: these are not good commuter tires as some would like you to think. I had 3 flats in ~ 400 miles before having a devastating blowout in the tread/sidewall 20 miles from home. I rode on the same roads as I use my gatorskins and other tires. gators
are without the same issues. I know people probably think I am doing something wrong or a "heavy" rider etc. I am average build and weigh 170lbs. I am an experienced rider with road, mountain and commuter bikes. I am not a conti hater. these tires just aren't the answer for commuting unless you want to change lots of flats in the cold, dark rain or snow.

The good: light and grippy, even in the wet and in gravel. Always felt secure even on really questionable surfaces. A fast ridding tire as well. They ride quite a bit faster than Gatorskins and have surer grip and handling.
The Bad: Just didn't last very long before the sidewall blew out. Maybe it's just bad luck, but I didn't hit any major potholes or drag them around sideways. Did ride some rougher roads than I wanted to, but that's the same for any tire. They don't last the way Gatorskins do.

In the end, I'm going back to Michelins for my fast tires and sticking to Gatorskins for training rides.

I've been running these in the 28 mm configuration through the winter out here in Utah and I've been extremely happy. They offer plenty of grip and protection. Will buy again!

Since 2004 thru current, I used these tires for all of the Ultra-Endurance races: Furnace Creek 508, ADK540, Alaska Fireweed 400, and RAAM Solo without a single blowout. While going through one of the reservations in the Midwest the road had about a mile of broken glass, still no problem!!

Want a True tire to believe in? This is it "4 Season"

I've had these on my road bike for a while now. They hold up really well to my standards. I haven't been out in the rain with them, but have done a few rides where the roads were wet. They gripped a lot better than I expected. Being a mountain biker mainly, I had reservations about skinny tires and their ability to help keep me upright. I was pleasantly surprised. They also offer a good amount of resistance to punctures, I'm a big guy and ride out towards Antelope Island regularly. With all of the construction and debris on the roads, that's something I appreciate. I have had tires that were softer riding, but I would rather be riding, than be stuck on the side of the road fixing flats. Personal preference, at least.
Overall, I'd rate these as very good tires, and would buy them again.

They may be a little heavier than some other tires, but I rarely get flats. They are durable and don't seem any less nimble than top end race tires I have run. I regularly pick our glass out of the tires, but see a flat maybe once a year. The handle great too.

Use these tires all year round. I live in the Northeast and deal with rain, snow, ice, gravel and dirt. These tires have great traction and handle well in the conditions. I also use this tire a lot on a trainer and the tires have not shown any extra wear.

After many miles on too many tires to name, this tire takes the cake. It may be a bit on the expensive side but to me it is the most complete tire. It handles long training miles on beat up chip seal roads along with racing use. Puncture protection like a gatorskin but the comfort, grip, weight, and low rolling resistance like a GP 4000s2.

Got these for my husband, who says: I got these tires after the set of Mavics I had on my bike were shredded by the roads around Park City. The 4 Seasons are perfect for the variable conditions I ride in (unsealed roads, gravel trails, general rocks/gravel/whatever leftover from winter) and I’ve had zero cuts, tears or punctures over the course of about 1000 miles. They’re not as supple or comfy as something like a Vittoria Corsa but you know that going in with these tires and while you give up a little bit of comfort, you get durability and grip in pretty much all conditions you can throw at a road bike. Definitely a great tire.

Lighter than expected yet thick and with a soft ride. Excellent quality. Will buy again.

I used mavic, schwalbe, michelin, several other brands of tires before and usually upgrading to Continental tires. I am very please with the performance of this particular Continental brand. Compared to gator skin, this one has better grip at cornering and descending. I have put less than 300 miles so far and it feels brand new everytime I ride. I would recommend these tires. Good price as well.

Listen, all the top cycling tire companies (Vittoria, Continental, Michelin, Schwalbe, and a few others) make great top-of-line race tires. But all those tires have very little flat protection (if any). They are meant for timed applications on clean, smooth roads.

What about the roads most of us actually ride on most of the time??

What if you want a great, fast, training road tire with some real flat protection?

These are the best I've found. The German-engineered (and made) Continental Grand Prix 4-Season.

Conti GP 4S tires feature *two* layers of Vectran tread protection, wraparound DuraSkin sidewall protection, plus the latest German rubber compounding for optimum wet and cold weather performance. And they weigh only 241g for size 25, and 280g for size 28. That's light for a performance tire with double tread protection.

These GP 4S tires are fast, ride beautifully (smooth & supple), grip really well, and have excellent puncture protection.

Coming from Vittorias that excel at smooth & supple (but cut and flat easier), I am really impressed by these Continentals!

Continental makes OEM tires for Porsche. The sidewalls are proudly stamped, "Handmade in Germany." These tires reek of high quality.

I just switched onto these for my winter tires, replacing a pair of fast but worn Vittoria Corsa Evo CX II's. The Vittoria's were 25mm but measured 26mm on my American Classic Victory 30 wheels. I opted for the 28mm Continentals, knowing that they measure a little narrow, but they were even narrower than expected at 25mm!

For tubes I got some of the Continental Race 28 wide tubes which are advertised for 25-32mm tires. The Contis were very difficult to get over the rim, and I pinched my rear tube a bit when getting it on, only to discover the tube was flat the next morning. I happened to have a regular Continental Race 28 for 20-25mm tires, which fit much better, and wasn't a risk for a pinch because of the narrower profile when putting back on. I'll also switch out my front for a narrower tube soon.

While I'm a little bummed that my winter tires are narrower than my summer tires, I really like the confidence in the corners on both wet and dry roads. I've been testing different inflation psi, and haven't got it dialed in exactly yet, but they are comfortable and still fast at 95-100 psi. Closer to max inflation, they were a little rougher riding. Also, I have noticed a little more rolling resistance and slightly slower spin-up than my last tires, but I was expecting this as a trade off of the grippier cold-handling compound and heavier weight.

All in all, a fine shoulder and winter season tire, and I definitely feel safer in the rain in these which counts for a lot on those dark winter commutes. Next summer, I'll get some racier tires again, but these will last me fine until then.

I have had issues with sidewall cuts/tears on the GP 4000S tires and finally got fed up with going through a tube a week. I bought the GP tires and have over 900 miles on them without any issues. None. It may be marketing but yes, these tires are not ready to roll up to the start line at your local crit, but I have no issues cornering down mountain descents at high speed, they grip well and are durable. Not a single issue despite lots of roadside debris, etc.
If you want a long wearing, highly puncture resistant tires from a great tire company, throw a pair in your cart now.

Before I bought these tires I had switched to another brand and had about 8 flats in 3 months costing me quit a bit of money. I purchased the Continentals a little over month ago and I haven't had one flate. Will definitely buy again.

I've been using these tires all around the San Francisco Bay Area. I typically ride through wet, dry, cold, hot conditions on smooth, bumpy, rocky, trails all in a single ride. These tires hold up perfect for it all. The tread feels grippy in the corners and on wet surfaces. I bought an extra set while they were on sale so I can continue using them as long as possible.

I am not a veteran road biker and so have tried to get equipment that will last long and still perform well without breaking the bank. I think these are great value, have never had any problems with them, no flats thus far so thumbs up for sure

Smooth and no punctures. Could not be happier.
