That is why you need to weigh each axle correctly. I think everyone has less than the max weight that the tire can carry. I for one want a little margin.
So the inflation tables should be used.
You will see that the highest value in the table will match the psi & lbs printed on the side of the tire. Higher than needed psi will give a rougher ride.
