Its moreorless equivalent to running 23mm tyres at 140psi - that is high.
The front must be rock hard and I presume very uncomfortable ...
A good 4.5 bar, should be 65-70 psi. Old habits die hard and I still don't understand the purported physics of the whole fat tyre thing. The pressure does decrease quite a bit between refills without any noticeable change in handling. The Big Apples have 4 bar in them at fitting - that will be down to 3 bar/45 psi or so by the time the ice on the roads has gone. I am itching to try them out.
