First Generation Correct tire pressure for P245/45ZR19 on R-Spec Sedan

[kg4pto]

What is the correct tire pressure for these? Should I just set them to the same pressure the 235s were at?

Correct. The tire pressure setting is inside the driver's door. But you can then tweak a bit to suit your preference. Just remember that over or under-inflation cause uneven tire wear.

Technically tire pressures are specified to the tire load capabilities for the vehicle they are installed on.
Example (not fact, I didn't look it up) - a 235/45/19 is rated to support 1000lbs at 35psi and a 245/45/19 is rated at 1100lbs at 35psi you could then do the math to figure what tire pressure you could run in the 245 to equal the same pressure of the 235. It may affect wear but in theory it shouldn't.
