Can you recomend a reliable manual tyre pressure gauge?
I use 3 modes of transport: a small van (tyre pressure 35psi) a motor scooter ( 25 & 30psi) & a cycle (80psi). I have tried 3 different tyre pressure gauges:- an analogue one; a small hand digital one & a 12v digital pump/gauge. Each gauge will give a different reading from the same tyre, often differing by 15%.

Not for all three types of tyre. Use a bicycle specific one for the bike. Use a barrel dial type for the vehicles.
