Be careful using the side wall pressures, they are the Max pressures and should not be run at those pressures. Remember that when a tire gets hot from riding, the pressure increases about 3-4 Lbs , that would put you over the max recommended pressures.
The front tire on my RG has 40 PSI max listed on the side wall that is way over the recommend pressure of 36 for my bike. Running it at 40 would result in the tire riding high in the center , that would increase wear in the center and reduce traction.
I would also casue handeling problems on roads with groves running in the direction of travel in them.
Just as running them to low will cause the edges to ware and allow to much side wall flex.
On a tire the size of a motorcycle 4 pounds in a considerable amount to be off.
Welcome to the forum. It would probably be best to follow the manufacturers recommended pressures printed on the sidewall of the tyres.
