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.

I was pointed at some comments on one or two forums. I wont bore you with them - as there was a lot of BS to wade through (you know a bit like the DS wars on here).

But it turned out that on a lot of CARS (yes CARS) the optimum pressure always turns out to be approx Max -10%. This from guys who do track days as well as use their beasts on the road. Most get improved mpg and mp/tyre) without loss of grip or wildly accentuated uneven wear patterns. I've not looked to see if any bike groups have tried. It may be pure coincidence - but it's worth a try imo.

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

They also use calibrated gages.

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.
