What should my tire pressure be after swapping my 225/40/19
square run flat tires to the same size Pilot Sport 4s? The side panel in the door says 38 front 42 Rear. Do I keep it the Same? Thanks

I think it is safe to keep it the same, but the manual or iDrive menu may offer a different pressure to optimize summer tire performance than all seasons. Go into your vehicle menu and see if you can change tire type to summer, and see what pressure it recommends.
