New Michelin Power Cup Tubeless: GP5K S TR competitor

[mario27]

I received the package with two 25mm clincher. I had previously the 5000s from early November. November until early June made ~10500 kms then switch the front with the rear. Fitted today the michelins after 15000+ kms. Still some rubber but I didn't like the feeling anymore. It wasn't a supple tyre and become worse after a summer with 30-40C temperatures. I hated them the last months, I could feel anything coming from the road even with 65psi for 25mm. I never had flat at 15000+ kms except two times from the tubeless tape I had on (it was time for new one ),it wasn't tyre related. The other issue I had is these didn't wanna go inside the rim or couldn't take them out. I swear to god, never had this issue with any other tyre. Some wired tyres for city bike were much much easier. I guess you can't have everything
Michelins bead to bead is 67-68mm(5000s are 65-66mm).I have seen some photos at 70mm, I don't think that's a 25, more likely an error from factory that was supposed to be 28?
One was 221gr the other a bit less. I fitted the heavier at the back , probably more thread thickness (I did the same with the 5000s last year )
The tyres sit at 27-27.5 with 19mm inner at 65 front and 75 back.
Yes is a bit larger than normal but are you guys measure and riding the tyres at 90-100 psi at these big volume carbon rims? These 28-29 measurements doesn't feel right to me unless we are talking larger inner or for 70mm bead to bead tyre or 90-100psi which isn't real world feedback because isnt rideable at these numbers
Bead to bead matters most and then the inner width and psi

I have these from mid September. Mid march change front back with around ~9000 kms. April and May had 1750kms each. Now they have almost 14000 kms. The rear tyre (had this at front before swapped them at March) has some issues with at the side of tyre for 2 months, no issues though. The last 2-3 weeks some issues at the middle of the tyre, there is some detachment of the rubber. For reference i weight 55-58kgs.
My review is they are like the 5000, they roll fast, I had one puncture in 10 months=14000 kms (same for 5000) and are more supple than 5000 but I had these issues.
BRR also says tire thickness for 5000 is 3mm (a lot) and for these are around 2.5mm, so probably less mileage.

I bought the 5000 again and I will change them the next weeks

Got back from 2 weeks in the Alps/Dolomites, including La Marmotte and the Maratona.
Mostly used Farsports Hypers 50 with 24mm internal, with 25mm Michelins mounted (WAM 30.5mm)

Some marks on the sidewalls from aggressive cornering visible. The rear had 2 small rocks embedded in the casing which didn't penetrate the puncture protecting layer. Overall the tyres performed great.

Just a note - comparing with another pair of Power Cups, which have only seen flat riding so far, these visibly look more worn with 30% less mileage (2000 vs 3000km) - obviously, the rider is the same. So this must be taken into account when speaking about tyre mileages, too, as riding in the mountains seem to accelerate the tyre wear rate quite a bit.

Had to bin rear tire after about 3500km. Thread had rubberless spots after two animal encounters and about 10mm sidewall cut with slight bulging but the casing held. Overall I am quite happy with these, tubeless setup was really easy, these hold air real good and ride quality for me is good. Zero punctures and I did some gravel sections too where I assume the sidewall got cut.

Dont think I would get much more than 5000km out from a rear tire as it was quite squared off.

Have to switch GP 5000 S TR to rear.

Pro One ahead of Power Cup is very German of them. Haha. The Pro One is worse than the Power Cup in EVERY measure on BRR (RR, grip, and puncture resistance)

BRR is hardly the bible for tires. Nothing is. User experience can vary greatly to lab tests.

I had Pro Ones before switching to Power Cup. In my experience, the latter rolls significantly faster but puncture protection is weaker. The Pro One lasted until the thread wear indicators almost disappeared. The Power Cup, on the other hand, both front and rear already suffered puncture (sealed by sealant) after, on average, half the mileage of the Pro One. The front had a puncture on the (tan) sidewall. I don't race, nor corner aggressively, which tells me it's the weak sidewall. The ride is also noticeably harsher than the Pro One. Since I don't trust the reliability of the sidewall, I now inflate them at higher pressure than what I prefer; so the ride is even harsher. The only thing I like about them is they are very fast. But just not reliable enough. (Not to mention tougher to mount on my wheels.) To me, these are like TT tyres. I have one spare left. Let's see if it's bad luck or the norm. If that last unit gives me significantly higher mileage, I might buy them again (they are relatively more affordable). Otherwise, back to Pro One and 5000 STR.

Agree that user experience can vary greatly - not only to lab tests - but also from user to user.

My experience on power cups compared to pro ones is:

I've had my sufficient part on bad luck puncturing both, I would say... with the same frequency and in identical circumstances.

Both had they difficulties dealing with puncture sealing, no matter the sealant used.

I have no discernible opinion on tire wear between these two, and they both have been ridden in the same circumstances.

99% of my rides involve a great amount of hills. For each 100 kms I can't make less than 1300 meters of elevation due to the geography of my location, so this involves fast descents, which on my better days I make with determination, cornering faster than many cars which make the same descents. I can't complaint about cornering grip on either one and I've set my counter part on PRs since I ride with Power Cups (more than a year now)

Power Cups rolls way way smoother in my opinion. This is probably the number one reason I've decided to stick with power cups from my very first set of tires. I do feel that they are suppler in all circumstances, giving me the impression that I'm riding on a smooth garage floor in many circumstances.

They are usually cheaper than pro ones and GP5k, which is a win win for me.

For more than half a year now that I've decided to go back to tubes, so I'm now riding the clincher versions of power cups on 2 of my bikes. One with Boras WTO 60 and another with LB AR46 rims. Both wheels have a 25 front and 28 back combination. I had no punctures after turning back to tubes. Hope to continue that way.

Interesting. They do roll nice and fast on smooth tarmac but over cracks and bumps, it felt harsher. I'll have to go back to the Pro One to double check this.

My 25mm Power Cup TLRs measured 29.4mm on 21mm rims, so of course they felt supple. They were basically the same size as nominal 28s.

[BigBoyND]

These are some of the most supple tires I've ever used. I can't believe anyone would think they're "harsh"

[AXA]

Second times I had problems with the narrow thread and today I crashed while cornering in a criterium. 28 mm on 21 mm rim. Back to Continental and Pirelli.

Sorry to hear that dude, I hope you're OK and not too much damage to the bike.

Regarding the tyre, f-me where's the tread?!? Is this some kind of strange cost cutting drive by Michelin? Less tread = cheaper tyre? Bizarre product idea, I would not feel safe on it and I don't ride crits.

[TobinHatesYou]

Less tread = a less rigid tire, weight reduction, cost reduction. It’s mainly used in this case to reduce Crr. It would be a great tire if it gave up a watt for an additional few mm in tread cap width.

[toxin]

Also, for some reason, it was designed for <20 mm internal rims. Dunno what they were thinking

The 25mm tire even has sidewall max pressure ratings for 15mm and 17mm rims.

That's quite extreme. Looks like the wear is 5mm to the side of the tread, which would require about 50% tread coverage. Conti and Pirelli don't have tread that far, either. They will just give you 2mm more on each side. Only the Tufos come close to covering that area.

[naavt]

I believe Michelin to be very aware of what's happening and what's being said by hundreds of users around the world regarding this issue.

If they continue to do nothing about it and supply World Tour teams with it, it's probably because they stand for it somehow.
