Continental Grand Prix 4 Season Folding Bike Tyre

Bought these for added protection. I ride 25 miles a day on various conditions of dry/wet/stones/thorns/glass. Tread is not much, but my hope is it is enough for the wet conditions. Smooth ride even with the tread. Wish they had directional information to provide peace of mind on the water shedding aspect.Update: 2-months and my first flat. The tread had a big gash about the second week. It did not go through then it lasted another 1.5 months before the flat so guess the high TPI worked. Retrospect, I would probably save the money and buy a thicker walled tire. The thin wall would be nice for racing or something, but not worth it for commute. Tread is just enough to help stop sliding under wet conditions.Update: 6-months and several flats later. Every tire will get a flat so not too worried about that. My back tire is really worn and the front is looking pretty good. I need to rotate them (should have done sooner) to even the wear. The side-wall gash in the second week was in my front tire. Now the back has a 1/4" long gash that went through and cause several flats until I found it. Installed a vulcanizing patch on the inside of the tire and has held for the last two weeks. I just bought a less expensive tire (1/2 this price) but will wait until these can do no more to compare. Still a good tire, but if any tire will have problems, might as well save a little money.

I had multiple flats before installing these tires and the tire liner I bought as well. Not a single one since! These are solid tires, very sturdy. I commute in the city and unfortunately there’s a lot of broken glass, but I haven’t had any issues since upgrading to these tires!

The media could not be loaded. Works fine. Nice and sticky. Comments about it having higher rolling resistance seem true. Feels amazing cornering tho

These tires are, in my opinion, ideal for hard day rides and some commuting. They are very puncture-resistant, but pay for it will a little extra weight. They are also super grippy on pavement, but wear a little fast. But for the puncture-resistance and the grip I get, the trade-off aren't bad. I guess you get what you pay for. I've stopped shopping around for tires, and just replace worn tires with these.

I like Continental and have tried three different tires now. For the kind of riding I do (in Korea), where there may be slight debris and some unpredictable surfaces near the shoulders of many roads I ride, I've liked the Grand Prix best. They give me a little added toughness and confidence with the slight tread surface. The one complaint though? Sidewalls are too fragile. They're great if you're careful, but if you don't hit stones or debris squarely, you're a bit unprotected. I glanced off a stone and it sliced my sidewall and gave me a flat. I repaired the flat, but once i had the tire on I noticed a slight bulge in the area and upon further inspection saw that it was only being held by a few hardy threads in the sidewall. I made it home, but replaced the tire immediately. I would say that as long as one is careful not to hit any stones at an angle (which hitting stones is never one's aim anyway), these are great tires.

Easy installation, although there were no rotating direction markings on the sides. I did read in a post that the "thumb prints" should be facing forward when looking from above.Also, I did end up pinching my new continental tube, but didn't realize it until after inflating to the recommended pressure of 120 PSI. I had to use my tire tools to take the tube off and replace it. Luckily the tubes I replaced are in decent condition, so I just used one of those. I am concerned about using the puncture-resistant tube with these new tires though, since the tubes and tires are both thicker than normal racing tires and tubes.Seem to be very durable, especially compared to my previous tires, which were primarily for racing. I will provide am update after about a week, or 100 miles worth of riding.

Great tire, rolling resistance is a little high as expected compared to performance tires without puncture resistance, but not much. The grip and strength of the tire more than compensate for any loss in rolling resistance.Tires received were brand new with no defects

The only bicycle tires I buy anymore are these, or the Continental Gator Skins. They last a long time and handle great, and very puncher resistant.
