Do you have a reference ? I would like to check if the 25-27mm tire on 23mm iw wheels is still withhold. I don't have any intention to be a test object and don't want to risk going down due to some mismatch.
That said I run hooked rims 23mm inner and use pirelli 26mm on them. 25mm gp are smaller I found out and did t want to use them. The Pirelli's p zero clinchers fit as for example a Ere research 28mm at the same width and height

I'd like to see it too. The link I posted is saying 2022. 28mm tyre on a 25mm int tss rim is ok according to it. The old P-Zero race certainly works on those sizes I posted here.

Apparently there is a new one. I'm not paying 175 Euro though.

With an internal width of 21 (CLX50 from 2019), how wide is the 26mm version, inflated for a 67kg rider? I need to replace my GP5000 TR (non S) 25mm, with a high performance race tyre, with tan walls, and have pretty much narrowed it down to this model. Wanted to go 28mm but it's for an alpine grand fondo and I am worried about weight.

Opinions?

26mm should be specified for 18-19mm rim. On 21mm I would expect 27mm WAM.

Both front and rear show crack/seperation all the way around, on both sides. Tires are little over one-year-old, 1500 miles. Somehow they look more like seperation of 'tape' than crack to me.

"...some products might not guarantee 100% retention of inflation pressure on some rims currently on the market."

Don't they mean the tire might blow off the rim for no reason and you could die?

I read that as they would deflate faster than normal (not suddenly) on these rims which is understandable.

It's still the same recall that has been mentioned a month ago here isn't it?

A couple riders around this way have suffered from the "catastrophic and sudden".... think that is the main risk

Oh it's a quote from the recall. I didn't realize that before. In that case I agree with you.
