Continental Unisex's Grand Prix 4 Season Tyre, Black, 700 x 25 C

My preferred bike tyre at a good price and delivered quickly. Lasts a reasonable amount of mileage and not too many of the dreaded punctures when in the road.

not quite the rolling resistence of GP5000s but the added wet weather grip and puncture protection make these the goto tyre for social riding and commuting.

If you want good grip in all conditions combined with outstanding puncture resistance then these are the tyres you want to put on your road bike. I live in south Oxfordshire and during the Winter in particular the roads are usually covered in razor sharp shards to flint. I have used these tyres over the last seven years and have only had three punctures when they have been on the bike. During this time I did try out a set of OEM original tyres that came with a new set of wheels. They got shredded quickly; got three punctures on one ride. So I threw them out and changed back the Conti Grand Prix 4Season. Not had a puncture since. Recently bought this tyre to replace a worn out 4Season tyre on my rear wheel.

I use these on my reasonably decent spec hybrid. The tyres can be fad though mostly I am towing one of the kids on a tag along. I have had these over gravel tracks, on the roof of the car for over a 1000 miles, in 40 degree heat in france, wet, dry. I have had one snake bite puncture but I was more off-road than my particular hybrid is designed for. Still look like the day I fitted them

I have just purchased my fourth consecutive 25mm GP 4 Season Vectran for the back wheel. I prefer the noticeably faster GP4000 but found them insufficiently resistant to nicks and cuts so now I only run the GP4000 on the front.Two of the GP 4 Season lasted a decent 6000 km. (The other was severely cracked after less than 1000km.) At 6K the tread is thinning and wearing flat over a 6-7mm width. The seam becomes visible on the side wall and the thin remaining tread cracks across the running surface (see photos). Elsewhere nicks from grit and flints are small. Small cracks do not extend with time.The balance between rolling resistance and puncture protection suits the roads and my riding. I find winter tyres are too heavy; summer tyres cannot last on winter roads or poor surfacing.The only downside is the lowest selling price on the web increases a couple of quid each time.

This was probably one of the best purchases that I have made for my roadbike that I use to commute on a daily basis. I live in Scotland where the roads are quite variable and the conditions are often quite harsh for cycling. I have been using these tires for about 6 months now and I barely had any punctures whatsoever. I am a heavy rider (>100kg) and on stock racing tires I would be getting punctures on weekly basis. This is no longer the case with these Continentals. I have done over 1000km on these tires and they are still in great shape and offer me peace of mind when it comes to punctures. The only problem with these is that they are slightly heavier than your regular racing tires (as is to be expected) and they are not as fast.

Was getting so many punctures with my old tires and spending a fortune on inner tubes so I decided to change the tires, looking around I found these and even though I thought they were quite expensive I went with them anyway, when they came I could feel they were a lot better quality than the old tires I was using so I was pretty happy, on the bike they feel great too, I've got every confidence to lean it over and keep a fair pace around bends and the they also seem pretty good in the wet even though I don't go anywhere near as hard in the wet lol I used them throughout the winter and I actually did come off but that was due to a super slippy random patch

Was debating these or the gator skins- was some reviews and look at comparison data and half I went with these. Fast and durable, plenty of grip, quality you would expect from continental!
