29 lbs of Nitrogen in 40 lb tires?

Naw, I don't think so ... But that's what they specified when they sold me my new limited...
It's right there on the yellow door sticker that reminds me of the tag on pillows.

Nice Tires on shiny chrome
Bridgestone Dueler HT 840 P265/60R18 109h-M&S

These nice Bridgestones that say they can take 40 cold on the side.
When I checked them, they were 28 to 31 (Nitrogen) ...

So just to be fair about it ... I added AIR and set them all to 33 until I get it figured out.
I don't want to fake a smooth ride like a 98 Explorer ... that didn't work out ...

It may be a TRD ... but it's a Limited and I hope that there is a reasonable compromise ?

What do you guy's think ... At this point it makes just as much sense to put helium in them so that you will get better mileage ... Don't tell me molecule size of nitrogen is bigger than polluted air is either, it's not ...

What lbs?

 

The 40# on the sidewall is Maximum inflation pressure. The plaque in the drivers door jam is the recommended pressure, 29 on my TRD Sport Access cab. I keep it to 30# on all 4 corners.
