18 SXE. What PSI are you guys running on those 19x 40 Series tires?
 

We just got this fella and it’s my first time relenting to having those high $$ / performance tires and rims. The door post says 32 and tire says 51 PSI. I’ve always run my tires near or at max tire stamping but these dudes are a fit stiff at 50. So what do you folks usually keep yours aired up to?

Assume the previous tires had a max rating around 44 PSI. Just because the new tires are 51 doesn't mean one should use this. At a MAX tire load at a MAX pressure.

Suggest you start out at door post PSI and work up to a max of around 41 PSI (cold).

Tirerack.com has a lot of articles on setting tire pressure.
