25cc Continental GP4000s II vs Michelin Pro 4 Service Course
Moderator: robbosmans
I am sure this question has been beaten to death.
But I am looking for a new set of 25cc tires, not a racer, and doesn't put huge mileage, roads are usually decent here in socal.
I wonder if I should go with 25cc Continental GP4000s II vs 25cc Michelin Pro 4 Service Course?
Look for a set of tires that are durable, but has good overall grip and won't give me any surprises in cornering or braking.

I had Pro 4 in 700x23. They road great but lasted only 1000 miles. I had two times that I almost got hit in traffic and had to lock up brakes and skid a little and people have told me I can't expect more than a 1000 miles out of those tires because of that. I just replaced them with GP4000s in 700x25. So far I'm very happy. 23 vs 25 so not apples to apples but I am running about 80 psi in rear and 75 in the front and it's like riding a beach cruiser but handling on windy descents is great and I feel glued to the road and still plenty fast
Don't think you can go wrong here - have used both, probably like the ride of the Pro 4 a little better but I would let cost sway my decision. Which one is cheaper?
Have found both reliable, Pro 4 seems to cut up a little more but didn't seem to provide any more punctures. I also remove glass and stones embedded in tyres regularly.

running 23cc Continental GP4000s II front(width 24.7 mm, 80 psi) and 25cc Continental GP4000s II back(width 26.5mm, 100 psi) [rim width 24.2mm]... done 1000km. Good traction and wear characteristic. Thumbs up !

Both are crap
1. Conti : 25mm, sidewall exploded after few hundred km, replaced by Conti : 23mm, Flat after flat after flat... finally exploded too ( sidewall ). Less than 1000km on both sets.
2. Michelin : 1 flat per 300km average. Rubber start to look like 135y old after about 1000km. thrown away.
To compare :
1. Veloflex Corsa 23: first flat after 3000km, still some life in front of it ( I believe 1000, maybe 1500km )
2. Vittoria CX 25: about 1000km , few tiny cuts, 1 flat ( on gravel ). I doubt it will stand more than 2000km more.
3. Schwalbe one 25 : 2000km, zero flats, bit slower than veloflex, bit faster than Vittoria, but less comfy. on rear some wear start to be visible after very close inspection. lighter than Vittoria, 24.5mm on 15C, 26mm on 18C rim.
For m Schwalbe One is better version of GP400s2 : zero flats, faster, more comfy , without fragile sidewalls. Perfect grip regardless dry/wet and low temps. Most "confident" tire in difficult conditions.
And reading that consider, I'm not a huge "fan" of German products, prefer "Italian". But if smth is good, it's good.

I'd agree with this. I bought Schwalbe one 25mm tyres last summer, the shop said they were `a bit fragile' how wrong could they be. Here in Kent tyres suffer very badly from the flints on the road, they'll cut through anything, well so far not my Schwalbe Ones, not one puncture in seven months.

GP4000s II are definitely a good option if you are racing due to their rolling resistance. Since you don't race, go with the Michelin as it won't be as fragile as the Continental and if those are your only two options.

I find the GP4000s to be more resistant to cuts than the Michelin pro4s. They last about twice as long, corner as well, and have better traction in the wet.

I can only confirm I've been running GP4000s (and II now) for years, and they are really indistructible, last around 3000 miles in the back, maybe double at front (GP Attack, and not 4000s at front). I've been doing some gravel roads, terrible forest "roads", cobbles, name it, and apart from 1 or 2 flats in years, typically at their very end of life, nothing negative to mention. They roll well, and are light as a bonus. Don't understand how some guys here can have that much faillures with them. Bad luck can happen ones or twice, but not every 100 mile
Been trying some aged Veloflex Corsa's 25 at the moment, and after 500 miles, so far so good, no flats, but the rear already starts to wear. They look like tubulars, wich is cool. Ride quality is not really better than Conti at equal pressure. Dropping to 90 PSI helps a little, but I think I will switch back to my trusted GP4000 when these are shot. Or Force + Attack on the Addict.

Gp 4000S is a Good tire been using them for about 3 years on 2 bikes but sidewalls tend to crack at least lately that has been my experience. Made the move to Michelin Pro Endurance and so far its been great 1000km no flats tire still looks great.
4 sets of Pro4 SC have lasted about 3500 miles each on all manner of roads and conditions. Conti 4000s (same tyre as the s2) got me about 300 miles less. Based on that the only reason to buy the Conti is if you're racing as they have a lower CdA. As has been noted 25mm Pro4 come up at 27mm+.
