Listen man...a damn $45 tire crapped out on me in less than 500 miles (less than 300 actually). I've since put over 2000 miles on a set of tires I paid $30/pc for. Call it luck, dumb luck, fate, carelessness, lack of skill...whatever..I do not care. There are tons of people that have sidewall issues with the GP4000 and I'm one of them. No matter what caused it...$45 for a tire that takes a dump in a month is crap and I will not buy one again.
Tell you what...I will GLADLY PM you my address and you can send me another GP4000 tire to match the other one I have. I will ride it all summer and come on here singing its praises of it doesn't take a dump on me.

i have the conti's gp4000s on my rain bike which has become my principal ride due to some repair issues required on my pedalforce. i didn't like them until i dropped about 5psi from the pressure i'd normally put into my schwalbe ultremos zx. the contis have very stiff sidewalls and to get them into the magic spot means less pressure.
By the time you're experienced enough to get something germane out of a test ride, you won't need a test ride.
Michelin Pro's are great tires for display bikes..I ride bikes so I gave mine away...Conti's are cool ...not supple..higher mileage...Vittoria and Vredestein are in another class for clincher tires .... almost a tubular ride but you pay $$$ for the experience.
Schwalbe makes some nice tires...did I mention I do not like michelin pro's ?
Just as a data point, I just threw out a GP4000s because I wore it to the cord. Got one initial flat on it about 250 miles from new. That was due to a large staple. I put a small patch under the hole the staple left, put in a new tube and rode until there was no tread left. The matching front tire still looks great and is well past 2500 miles with no issues. I've never had a sidewall cut in a GP4000s, but that's just me, and covers the maybe 6 or so GP's that I've ever had on my bike since I switched to that tire.
People can ride what they like, whether their decision is based on 1 data point, zero data points, or the world's largest study of all tires ever - ooh that would be cool to read. Have fun riding!
How long are you guys getting out of your GP4000S rear tires? I'm getting 5-6k miles before the wear indicator dots disappear. The front tires would probably go close to 10k miles at that rate. That is at weights in the 165-180lb range.

I'm a big fan of GP4000S but one feature I don't like is the bar code glued inside the tire. It's covered with a thin film of plastic that dries and cracks. I just had my second flat from it. I can see the imprint of the barcode on the tube. What gives?
You're just trying to start an argument to show how smart you are.
I liked the grippiness of the 4000s especially in the wet, thought they went where I pointed them pretty well, but quit using them after endless flats and 4 blow-offs. They'd be OK for a few hundred miles, then start picking up glass and flints and flat almost every ride. After having 2 flats in the snow on one ride, I got rid of them. I then tried the earlier Schwalbe ZX, but they flatted even worse. The DD wasn't much better. I've been on Michelin Endurance PRO4 tires for a couple years now, ever since they came out I guess, and they are the answer for me. Good grip in all conditions, good rubber life, and very few flats even as the rear squares off. And zero blow-offs.
I found that the sidewall threads on the gp4000 would deteriorate due to UV exposure, and they'd start unraveling. Still ridable but ugly.
