40 psi in 20" tires?
I have accelerated wear on the outside and inside edges of my tires, have previously been maintaining pressure at 30 psi. I noticed the wear and bumped it up to 34 psi. My mechanic suggested 40 psi. I have 20" wheels, 275 in back and 245 in front, although back tires really only have inside edge wear due to higher negative camber. Alignment has always been good. Thoughts?

I run my 255/35 and 275/30 20 at 50 psi with toyo T1r's.
Toyo has a calculator or each car to set the psi to and it showed 42-45 for me and my sizes. I uped it a bit as tires are cheaper than wheels.
