ContinentalGrand Prix 4 Bicycle Tyres

I bought a pair of these to use through the winter. Never took them off. I've put 2500km on them without a single flat, and little evidence of wear.I run them at 60 psi. They handle well, absorb little bumps, and I feel confident cornering and descending on them.Not not my first pair of Contis. Would have no hesitation buying them again.Do look forward to their making a similar tubeless ready tire.

I purchased these tires for our tandem road bike. I went with the 32 mm width to replace the old 25 mm. Huge improvement in ride quality. At the same pressure, the bike handles much better and is much smoother going over bumps. The tires themselves are very high quality. Our old tires were Continental Gatorskins which we ran for two years with zero flats. The Grand Prix 4 Seasons have much 'stickier' rubber and I'm more confident cornering at higher speeds. Great tires that work well on a tandem bike. I will update this review over the season.

These tires are incredible. I have the 32c size on my priority Apollo belt drive and commute EVERY day, rain, sun whatever, ride across battered pavement and potholes, glass, next to construction sites etc.No flats after 3 months. These are basically the same as the gatorskins but a bit more tread which gives confidence in wet corners. 32c pumps to 102 psi, hard as a rock. Not too difficult to fit on the rim and look beautiful. 🇩🇪 Hand made in Germany.You won’t regret these awesome tires.

I have used these tires for about a month and a half in NYC. Given how many of our roads are in NYC, the tires have performed exceptionally well. I even did the NYC TD 40 mile bike tour. What I like most about the tires are their durability and road handling. Now I can travel between Boros with ease. So far, I have ridden 500 NYC miles, and I still have several months ahead before the winter comes.

Not totally in the vendor's control, but I have still not received my order. I'm sure the tires will be fine when I get them as I've used them before (albeit not this size).

One of my two favorite road tires for fast riding.The other is the Schwalbe Marathon Supreme in the same 700x32C size.The Grand Prix All Season is a bit lighter and a bit higher volume than the Marathon Supreme. Also usually a bit less expensive (but that may be changing due to the current tariff situation).Both are more supple and higher performance than any tire with comparable durability.Much more comfortable ride than, say Continental Gatorskin tires.Dramatically more durable than Continental Grand Prix 5000 tires.All in all, if I were on the Pro Tour I would not choose these tires; but for fast riding in my club’s A Group, I think they’re ideal.

These are very tough, puncture resistant tires that actually handle well and have a good road feel. That's a hard balance to find. Continental seems to make the best all-around tires for commuting, road training, and long distance road rides. They're usually more expensive than competitors, but they last longer and the Grand Prix and Gatorskins rarely puncture.

I bought a pair of these for my hybrid to replace the noisy, poor-wearing Bontrager LT2s that it had come with. These made a world of difference, especially so with clipless pedals. Previously, I had to crank with all of my might to reach a paltry 22 MPH, but now I can easily roll up to 27, or even higher if I hammer it, all while rolling almost completely silently. The smooth tread is grippy on tarmac, and decent on fine gravel. I'll be buying another set when this set eventually wears out on me!
