Continental Grand Prix 4 Season Tire Review

Fahrräder, Tests, online, Rezensionen, Bewertungen

1. Nice tires, but color choice are ugly, they could have made a better choice of colors.
2. My experience with the 4 season is that it lasts about twice as long as a 4000S II in terms of miles. I have about 8k miles on 4 seasons over the last two or three years and have had ZERO flats with this tire. I normally run the 28mm version, but lately have been running 25's just to test. I'm running them at about 60f/65r PSI, and as a big guy (6' 5" - 240lbs) have not had any trouble with pinch flats.
3. What about the 28mm
4. fairplay that's a very informative review, I previously used the gp4000s and they were outstanding tyres. might give these a go next
5. If I have 23 mm on my bikes what do I need to check to verify that I can put 28 mm instead? 
6. I run this as my rear tire and it's very strong although it's durability is questionable. I have a gp 4000s up front and it's still has lots of grip and probably will hold up for hundreds of miles more. 
7. I only had mine for about a month and I sliced one open.  They're a very comfortable ride, but I'm not sure it's worth replacing an $80ish tire if I'm going to slash it open in another month.  I put a ton of miles on Gatorskins before managing to slice one open.
8. How do they perform in the cooler months in the dry?
9. It comes in 23 as well. This is my tire. No tire I've used has provided me with as many long stretches of flat free riding. My only complaint is that they could be prettier!
10. Is there a particular reason to go from 23 to 25 for winter city riding?
