I have been using GP4000 tires since their introduction, for a total of somewhere in excess of 25000 miles. They are tough, light, and terrific at cornering in all road conditions. I generally get about 3000 miles out of a set of these tires before the wear dimples disappear. This riding over largely chipseal roads. The only problem with these tires has been pointed out by a few reviewers, has to do with the sidewalls being somewhat fragile. I have only had to throw away one tire due to a sidewall puncture. It was upsetting due to it being a brand new tire, but I doubt that any tire would have survived that particular road hazard. I consider these to be about the toughest tire out there. I will continue to use them as long as they are available.
Just purchased these in April - 2nd set on my Trek Emonda SL6 w Aeolus 5s - I purchased the reflective tires this round - they are awesome at making you even more visible & my first ride out, I picked up a carpenter's finishing staple. No tube puncture or anything! I highly recommend these. I'll probably upgrade to the 5000s on the next round.
I like the 4000 S II 700C tires well enough that they're the only ones I buy. I bought two on sale at half price to keep in reserve for when the others wear out-eventually. The price was too good to pass up on tires I prefer.
Have ridden on this tire for 18 months in 28 width. Have always ridden 23 to 25 but after doing some more research decided to try the 28's. As with many things in life it's hard to admit that everything you thought you knew was right is proven wrong when you finally give in and try. These tires are not slower, they might be a little heavier but not enough to make a difference for most riders. Their toughness is amazing. I finally decided after a summer of riding to buy another set in preparation for spring. The current set has multiple slices that would have flattened other tires.
This is my go-to tire. It's a fast tire and they feel stable when I'm screaming down a descent. I've tried other tires that are more puncture resistance but I find that the Conti 4000S tires are faster. I ride in the SF Bay Area where the roads (and bike lanes) are in terrible condition with a lot of debris. I've had a run of bad luck lately with this tire though. In the past 2 months, I experienced 12 flats, mostly from broken glass and one flat from a goathead.
Our rough roads have eaten every tire I have tried (Michelin, Panaracer, including previous Continentals and a list of others). These were on sale and decided to give them a try, they are holding up better than expected with the use of kevlar liners and puncture resistant tubes-I spend time riding not repairing. I have been very impressed with the road feel of these tires and after a long ride I usually have slight cuts in the outer tire casing and so far no cuts.
Great tire for the money. I rode these tires hard for 1500 miles. Great performance and minimal flats. But once they're done, they're done. Just pulled the rear tire off this week as I had a slow leak in the tire. It was time to replace.
A friend recommended these tires to me and I've loved them. They have tiny marks in them for you to be aware of how much wear they've gone through and know when to replace. Didn't get the reflective kind but I think I will when shopping for new tires. Also rode in rain and they performed GREAT.
Well, out comes the GP 5000 for 2019, but I still look to the 400 for proven performance. You can't beat this tire reliability, grip, strength,....it has it all. I'll tell you how it lasts when I reach the 10,000 mile mark!
These are the tires I have been using for years and I love them! I used another brand before that I was happy with, but they were a pain in the a$$ to change, especially while out on a ride. The Conti's are great tires. They are fairly puncture resistant, the last a pretty long time (I have actually gotten several thousand miles on a set), and they are easy to take off in case of a flat.
I used to switch to lighter tires for a long ride or race. After several flats in crucial rides, I have decided it is smarter to just stick with my tried and true GP 4000S tires, they are good for 2,500 miles without a flat.
I have these tires on both my touring bike and my road bike. They are tough tires, I find numerous cuts in the tire from road debris but I rarely get flats. I use the 25mm tires and they give a comfortable and fast ride.
