Without having to dig through all the pages again (a search was non-conclusive):
Is the 25c Power Cup recommended (officielly) for 23c hooked rims (Aeolus RSL), as they will certainly blow up to 28-29mm when reading the comments here?
From my experience it shouldn't be an issue, but maybe people here disagree.

My 25mm Power Cup TLRs were 29.3mm on 21mm Aeolus RSL 37s. I imagine they’d be 30.5mm on 23mm Aeolus RSL 51s.

I do not recommend this pairing because the sidewalls will touch the road surface.

Are these tyres directional? Or it doesn't matter how I fit them ? :noidea:

I had the same doubt when fitting my owns and looking closely at the tire didn't found any sort of directional instruction on it.

I am waiting a package with two clinchers the next days and can't give any feedback about this. I saw some photos at social media from Michelin and Cofidis and try to understand.For example the logo and the word of Michelin is at both sides so couldn't understand :noidea:

Recomendations are on nominal width, ETRTO says 29mm for 23mm inner rim. We can debate if 28mm is safe (old norm), but 25 clearly not.

My PowerCups last time I measured are 29.8 on 22.4 and 30.1 on 23mm internal. (tires are 28mm) Personally I would run 28 + (not 25mm tires)

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 :noidea:
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? :noidea:
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 :noidea:
Bead to bead matters most and then the inner width and psi

The updated 2023 ETRTO guidelines recommend 29mm minimum for 25mm-wide rims. The 25mm tire minimum on 23mm-wide rims is unchanged.
