I'm new to this community so please instruct me if the question needs improving.

On an Acura 2010 TL SH-4WD, is the following reading normal regarding the tire pressure?

The tires are winter tires that were very recently put on by a dealership. What are the normal, average, bad ranges for these pressure numbers?

Should I be worried that the back tire on the right always had a higher reading the the back tire on the left and the 2 front tires. Driving was during 5 degree Celcius (real feel 0) and on a city road. The trunk was carrying a heavy load (the all-season tires) with the center of mass skewed to the right.
