Avon Cobra PSI

When it comes to car tires, recommended pressures are also a contributing factor to ride comfort. Increasing the pressure will usually result in increased mileage at the cost of a firmer ride. As to track use, there is an optimal hot pressure at which every tire will yield the best grip. I doubt that ride comfort is much of a factor in recommended motorcycle tire pressures. I tend to go a couple of pounds at most above manufacturer's recommended pressure.
 

They also use calibrated gages. The standard off the shelf air gage has about 10% error built in.

I use my neighbours calibrated gauge.

Here most gauges are surprisingly accurate and always show the calibration date and due date at garages. This I think because there was a move to make correct tyre pressures part of a planned roadworthyness check that LEOs could apply pan-EU.

I can remember being warned sternly about it when I first moved to Germany in 1990 - and the ADAC (German Auto Assoc) issued fine warning pamphlets in my Germany to Spain holiday travelpack. iirc France was very hot on it.
 
On the track we run very low( cold set) pressures, starting around 25-28psi.Obviously the tyre heats up a lot more on the track than the road, & wear rate is of little relevance compared to grip for short sessions.
