So 2 days ago, Tuesday, I went out and noticed a notification about my tire pressure on the IC.

All four tires are below the threshold due to sudden drop of temp here in NY.
Both front have 28 psi and both rear have 30.

The sticker on the door frame shows tire pressure as:
Front - 225/45R18, 35 psi
Rear - 225/45R18, 41 psi

Sticker is showing same tire size all around even though I have staggered setup as stock, 225/45R18 front and 255/40R18 rear.

I still put the tire pressure as 35 and 41 psi though as stated.

So questions are:

1. Should I worry about my rear tire pressure since the indicated 41 psi is said to be for the 225/45R18 when I have a 255?
2. That day it was low 40s and today it's 70s again so I assume due to gas expansion, my tire pressure is more than what I put 2 days ago. Should I reduce it?

Thanks guys.
