Good to know....

I have the conti's after switching from mich. The conti's are better. They are more puncture resistant, "feel" faster, last longer, better than mich in my opinion

I used Mich Carbons for over 1300 miles and they still look good...though I replace my tires after 1500 miles just so I don't deal with blow outs or flats. The rear wheel did have some cuts that I noticed which prompted their change....but the front tire still looked good.....both were replaced by Carbons.

I just bought some Pro Race 2s. I used Pro Race "1's" on a Trek 1000 and they are still going strong after around 500 miles....

My new bikes have all campy wheels and the Mich Carbons were hard to get onto 05 Scirocco and Eurus....which is a problem with most campy wheels....so I don't blame the tires....but I love my campy wheels....Scirrocco still true after 1300 miles.

1 more vote for the contis. Had the attack/force combo, shredded the rear and replaced it with the 4000.

Vote for the 4000's

4000

I've found variation in individuals of the same tire brand/types. Recently mounted new Pro 2s and GP3000s. On the latter, one went on without levers, the other I reached for the levers. High thread count Vittorias are the best riding clinchers I've used. I just wish their Pave came in another color than green.

I have GP 4000's on my bike now and can say that they are a good summer training tire. You'll get lots of miles out of these tires but the grip on wet roads is not inspiring. Softer-rubber tires (Conti GP 4-Seasons, Vittoria's) grip much better on wet or dry roads and have a smoother ride. The GP 4000 are tough if that's important, I hit some scrap metal on the side of the road last week that I thought would flat any tire but it didn't leave a mark on the conti's. Conti's in general are tight (I've used 3 different types of Conti tires) and the GP 4000's are right up there with the TT2000, impossible to hand mount and easy to fatally pinch tubes when mounting. Can't comment on the Michelin Pro 2's.

I cannot compare to the GP 4000 since I've only had the pro2race but I'm really enjoying them. Pretty much night and day compared to the specialized mondos that were on there.

4000 contis.

I've recently used the Conti 4000s and I can't say that I would reccomend them. As for the "vectran" belt which is supposed to be tougher than kevlar, well, tell that to whatever I ran over last weekend, sliced right through it like it was a wet paper bag. As for mounting them, well anyone who can mount them without the forceful use of tire levers must possess the kung fu grip of death. As for the ride, hope you don't have too many fillings you are fond of. If your rides take you over roads that are less than smooth they can beat you up. Grip, well, initially it is good and while good on smooth roads, they are so stiff that they tend to skip and richocett off of imperfections and bumps in the road. Hardly confidence inspiring.

Heard that from others too so I'm sticking to my tried and trusted Pro Race 2's.

I used both and now how a lot of miles with each (went through multiple pairs of Pro Pace and on second of the GP 4000). The Pro Race have a slightly smoother feel to them, get small cuts much easier, tend to get more flats from these cuts over time, and don't grip well when wet. The Conti 4000 are clearly more durable, have longer wear, have better traction for overall ride conditions, and inspire a little more confidence in tight turns.

Then you did something most can't......................get PB to match an online competitor! Kudos to you.

Well, after about 100 miles on the Conti 4000's I'm really impressed. The handling is super-quick, cornering is very grippy, and as long as the tread life is what everyone says it is, I don't think I'll be going back to the Pro2 Race any time soon. The Michi's are a LITTLE softer, but supple doesn't doo much good when you're sitting on the side of the road trying to patch a big cut in the sidewall.

I'm converted--GP4000's for me.

Here is an update on the 4000's for me, still no flats(which is very rare for me) but 1800 miles and they are pretty much done(I didn't rotate the tires, so it is really just the rear that is done)

I'll post some pics of my 3500 mile Pro Races this afternoon. The bead is seperated from the sidewall, and there are numerous cuts, one of which had the tube poking through. I have GP3000's that have comparable mileage, and they look brand new. That being said, they dont begin to ride like the Pro Race.

You know, the fact is, you take the things that matter to you, and you make your decision. I get a distinct tire hop with the Pro Race on and the Tire spun in the mount, but no hop with the Conti. The Conti is stronger, but not as supple. I mean at this point, I am sticking with GP4000's, but the Michelin is a FINE tire. You just have to know its strengths. Michelin encourages the Carbon as a day in day out training tire and the Pro Race as (oddly enough) a race day tire. So if you compare the life and durability to one of Conti's pure race tires, I think its much closer.

My experience is that the GP 4000 S are very difficult to mount. If you buy them from your LBS, let them do the mounting the first time. The second time you mount them, it will be a little easier.

Grr I just got a small gash in the sidewall of my brand new P3R's (which I was really happy with until now). I booted it with a dollar bill, but should I try to put a better patch on or just get new tires?

My first pair of 4000's lasted about 4000 miles. They were showing some wear, but I replaced them after getting a gash in the rear tire sidewall. I just noticed that my second pair are looking worn and bought another pair ($59.99 at an LBS College Park Cycles). Then my LOCAL LBS (Capitol Hill) mechanic said he'd keep riding the old ones. So for a little longer I'll keep the old ones on. It turns out they have about 4000 miles also. Mostly smooth roads, some chip seal roads, and several miles of dirt and gravel roads. I weigh about 165.

The PR2 are more susceptible to cuts, but I like the feel of them on turns a bit more. The contis definitely last longer.

holy thread revival...... P2R is no longer in production, only ones left are all snapped up and hard to come by.
