I used to do that, but ride was rough, especially when driving in high temperatures. It adds about 4-6 PSI. And wears tires unevenly.
I'm currently at 36/37 F/R per digital air gage. Car shows +1PSI. Ride is ugreat, comfortable, on awesome Toyo Proxes ST3, 285/40/22

yeah, 36-38 psi range seems to be good for both of our vehicles. 20in wheels. Still don't understand the reason for 45psi sticker. GLS suppose to be comfortable.

The tire pressures shown on the door pillar are for max load. Check out the tire pressure ranges shown inside the fuel filler door or in your owner's manual. Our 2017 GLS450 shows 32psi front and rear for normal load and 20" wheels.
