Marketers tell us, new and improved, but I cannot really tell the difference between the 4000 and 5000 tires, both roll fast and are susceptible to sidewall gashes. My rear Grand Prix 4000 and 5000 never wear out in the rear tire, they always gash out in the sidewall.
I have used Continental Grand Prix 4000 tires on all my bikes since they were first released and I did not think a better road tire could be produced. When I saw that the Grand Prix 5000 was being released, I ordered a pair the same day. The new tire is incredible and has lived up the the claims of faster, more comfortable, and more grip. I am impressed with the improvements.
After a week of riding this tire-and getting caught in the rain-I have to say I am very impressed. Not sure how Continental managed to improve on the 4000, which I've been a fan of for years, but these tires have noticeably more grip than other tires I've tried. Even while descending in the rain I was able to rail the corners with confidence. They also felt a bit faster on dry flats roads as well, but that's a subjective. I can't speak on durability or flat protection yet, but as an improved version of the 4000, I don't think either of those will be an issue.
The 5000 is the replacement for my go to 4000 SII. Improved rolling resistance, puncture resistance and grip makes this my new go to tire. It has the nice aero shape of the 4000 and rides just as nice. Highly recommend the 5000.
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.
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.
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.
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!
