... having max air in your tire to help stop rim Pot Hole Dents? A Local E-Tech mechanic said its Forged or keep the wheels fully inflated to help with Pot Holes. My door rail say something like 32 lbs for 17 x 225 x 50s at Front, but I am sure 19s take more air. Since my Potenza 960s say 50 max psi ; I put 40 in front and 44 at rear. What do you think?

It's always a trade-off, but that's a lot of pressure (44 lbs.). Got any dental work? Seriously, that much pressure probably will lead to excessive wear at the center of the tire. Depending on where you live, running 19s is inherently risky due to the low aspect ratio. I personally wouldn't go over 38 psi, but every response on here will be different, citing different reasoning. GL.

I roll in 40lbs of pressure on all my wheels. It already saved me once. The sidewall blew out, so I had to replace the tire, but the wheel was fine. I highly recommend it.

Air pressure does not depend on the size of tire you select. Follow the instructions on side of tire. Modify pressure as you like as long as you are within limits acceptable by manufact.

In other words, you can locate tires that require 40 lbs. It does not make any difference whether tire is 13", 14", 20", etc. As my g/f never says, size has nothing to do with it.

I run 44psi in all four tires(F452) but surprisingly smoother than 32psiF/35psiR (Kumho Ecsta SPT).
