I agree and a complete waste of time without at least axle weights. I have always added a 10 - 15psi cushion over the chart specs. to take care of all the variables, such as on going, side to side differences, ambient temp. changes and possible slow leaks before they can be caught at the end of the day. Whatever the case, a little more is always better than not enough, which creates heat, damage and possible blowouts.
