Another option

Cheapest option but not necessarily the easiest one is a valve removal tool, remove a valve and count how many seconds it takes for the tyres to start 'bagging out' re insert valve, repeat on each tyre counting to the same number each time to keep each tyre close to the same pressures.
I have all three options in my glovebox so I can hand them to mates to borrow once I have done my tyres.
