I've not tried beyond 40 PSI with the X9 Pro but other reviewers say it can do van/truck tyres up to approx. 65 PSI fine, though I found it was starting to slow down a bit beyond 35 PSI compared to my more powerful one (which sadly isn't available any more).
Ended up getting a ring rtc450 for £25 delivered.
Wife ordered it at 4pm and it's just come with Amazon
I'll plug it in in the morning and post back.
It's said 100psi but I'm doubtful of that. Would need a proper machine for that I would think?
