E450 Coupe Fuel Filler Door Tire Pressure

The other day I realized 245/40R19 tires are listed in two places on my fuel filler door.
Wondering if the second listing pertains to using 245/40R19 on front and back?

I currently have 255/35R19 front and 275/35R19 rear (what dealer put on the car when I bought last year), trying to decide what pressure I should be using front/back for normal load.

It is a good idea to follow the tire pressures of the fuel cap just make sure it is checked when the tires are cold (so overnight or a couple of hours at least stationary).

Depending on your driving style and load, adjust up or down a PSI of such tire pressure, if you anticipate cold temperatures or warm temperatures in the coming days, also adjust accordingly.

Yes, this is what I want to do.

Guess my specific question is if my front tires should be 33 using the first tire section.
Original front tires were 245/40R19 and are listed in first section at 33 and second section at 35 for normal load.

Yes that is fine for the new tire size.

Disregard the sticker suggested tire pressures. They are set too low to sell you more Tire$$$$ & Rim$$$$.

(OR) Run around 38-40 PSI. Your tires will last longer, your rims won't bend & crack as often, fuel consumption will be less and you can cruise above 100+ MPH sustained (if needed) with less fear of a blowout.

If you don't mind spending money, as most MB owners fit that profile, enjoy the smoother ride 28-32 PSI provides you... then forget about the rest
