My Max sidewall tire pressure rating is 44 psi,
michelins xones i am pretty sure,
In about 14 to 18 months, the fronts get changed before winter,
costco will mount new on rear and put the old in the front, then the cycle starts again.
I run anything from 38 to 44 psi and in winter down to 35 or even 32 if I have to drive over accumulated snow.
in theory, yes, if you over inflate, then one is supposed to see wear in the middle of the tire.
but I like the increased mpg of have 5 to 10 psi over the door jam.
the downside is that it is bumpy, and I lose little bit of cornering traction (less tire in contact with the pavement)
