Why not put in 60psi and lets see what else go off.
Max mean you are not suppose to exceed that. When your car sits, the PSI for most tires should be around 32psi. This is a tiny bit low for the tire but when you are driving the PSI increase and on a hot day it increase much much more. But ideally even with the increase pressure due to heat, it still shouldn't exceed the max.
My tire was measured at 36psi and after driving on a hot day it jumped up to 46psi. It wasn't good so I decreased it. Anyway, I will replace those tires soon.
Any low or high pressure will create an uneven wear on the tire. Some put in high psi to save gas but with 4 tires priced at $700+, it will take a lot of saving to equal the amount it takes to replacement of those tires.
