I'm running the 25mm width tires, between 80 - 95 psi on 3 of my road bikes. My experience with the Conti Grand Prix 4000 SII has been excellent. Smooth ride, great grip, low rolling resistance and better than expected durability. I've had 2 puncture flats due to road debris in approximately 2000 miles. No pinch flats, no defects, etc. Tires are pretty easy to mount too. I've had the earlier version of this tire without the Black Chili and I do believe there is a noticeable difference with the Black Chili - more grip, lower resistance. Occasionally these go on sale, when they do, they are a great value. For reference I've run Conti hard shell gator backs - In my opinion the Grand Prix 4000S II are far superior. I also ride Vittoria Open Corsa and Open Pave - the Conti Grand Prix 4000S II are more durable , the grip seems about the same but the Vittoria are just a bit nicer ride. Hope that helps.

This is my 2nd time purchasing the tires. Great service from Nate every time.

These tires seem to last forever! I keep checking the wear indicators but they don't seem to wear. The only time I ever get flats is when they have already gone a couple thousand miles.

First time on these tires. Glad I got em. Roll very fast. Feel very supple. Nice and light. Reflecting strip on sidewall really lights up at night.

I have been running specialized s-works turbo tires for three years and love the ride ,feel and speed I get from them, but they wear out after about 1200 miles . I bought the continental grand prix s 11 on sale to see if they really preform the way I have heard . After 800 miles, they ride harsher, not as fast , grip pretty well , and seemed to hold up better ,but I will stick to my favorite tire , the specialized turbo

I've been riding these tires for years for general road riding on several bikes. I bought my most recent pair of Grand Prix 4000 S II to replace a pair of Schwalbe Ones that came stock on a new road bike. Schwable's are also high rated tires but never felt right to me. It's kind of all a matter of preference I suppose, but the Grand Prix 4000 S II always feel like their gripping the road better.

Long-lasting, great feel, even stops well in the wet. Not nearly as puncture-resistant as the Gators, but so much stickier.

These are great tires. I swore them off for a while after getting lots of sidewall tears, but have given them a shot again. I've got close to 1,000 miles on them and so far so good. I'd never pay full price for these tires, you can frequently find them on sale. I have 23 mms which look more like 25 mms on my carbon rims when mounted.

The combination of low rolling resistance, great grip, and terrific puncture resistance makes this my summer training and racing clincher of choice. You won't be disappointed.

LOVE THEIR ROLLING ABILITY AND THEIR EXTREMELY DURABLE AND EASY TO PUT ON MY BIKE

Tried the 25s and very tight clearances on my FLO 32 rims as wet weather attracts grit which rubs on the brake bridge. 23s are a much better around my Rival brake bridges. I like the ride and yes the 25s are nice if they fit but the 23s on a wider rim are very nice as well.

Easy to put on (and that's saying a lot because I suck at changing tires.) Not too heavy. Great road traction.

Great training tire. They handle well and are easy to install. On carbon clincher rims, I would suggest using hands only to install, working the tire around the rim until it slides in place. Check the wear indicators frequently. I run 25mm at 115 psi and the tires perform well with minimum punctures.

Never had a flat since I changed to these tires. I went with a 23 in the front and 25 in the rear. Rides real smooth and hugs the road. I bought another pair because they were on sale. Excellent tire.
Review by Lee
Love these tires. I get a full riding season out of every set with very few flats.
