is that just to see if they hold pressure, what size tyres ? one of the attractions of tubeless is the ability to run lower pressures for comfort.

I run tubeless Continental GP 5000 on carbon wheels. 7 bar is very high. I run at 5.5 which some would consider high.
Tubeless always runs at lower pressure than tubed for same Size/type tyre. That is the beauty off them. I’ve experienced the flaff setting them up but once they are sorted , it’s great. I reckon though they are more suited to bigger volume tyres. I’d imagine road tyres such as a 25c tyre would lose lots of pressure quickly if holed before the sealant did its job.

…it's wot it said on the tyres as max. (Mavic Yksium Elite 25). The Vittoria Rubinos on one of my other bikes run at 10!

MAX, not MIN!
I used to run 25s with tubes about 80psi, I run 30mm tubeless at 60 psi, I would try 25mm at 70 psi, I weigh 12.5 stones.

Agree, here 65 front and 70 rear PSI on 28mm Conti 5k

I have a friend who runs exactly the same. He keeps encouraging me to do the same.
I may try it but I have this thing about high pressures helping to reduce punctures.

As @ColinJ said this is the maximum recommended pressure. I've never heard anyone speak of using 10 bar (145psi). Most people I ride with would be below 7 (100) and in the region of 5.5-6.0 (80-90).
I've recently dropped from 105 psi to 85 on my tubeless Contis. Much more comfortable and no noticeable difference in pace or performance.

apart from the increased ride comfort i assume a lower pressure gives a better chance for the sealant to work

That's an interesting thought. I'm visiting my LBS this afternoon. I'll ask the question.
So say a tubeless will not seal at 100psi but will at 60psi, that will do me, tubeless punctures are often not as fast going down as tubed one's. See how I see it is somewhere between 100 and zero is the point that the sealant will do its job, most thorns I have pulled out of a tubeless tyre is 14, none made me stop riding, tubed they most likely would have. Just my view after many years of using tubeless.

It's a bit more complicated than that...
Me neither. But hello Charlie!
