and by having the 44psi and the extra wider tires, i got horrible center wear. i am currently affraid to go much higher than 38 at the moment w this size, to keep my tires nice and enjoy more grip and softness.
no center wear issues on the old tire size though.
so all this calculation stuff seems legit

I have 235/50/18 with no excess center wear. My wife's 255/65/18 have shoulder wear even at 5psig above placard recommendation. There is more to it than pressure alone.
