Deflating 3 mins from 35 to 14.

Are you using key to deflate?

You can deflate 1 tire in 10-15 sec with valve core removal technique.

Also why deflating to 14 on Expedition (too heavy). Does it has AT tires, if yes, then its fine. If on stock HT tires better stick to 16 for first few drives until you get used to desert driving with deflated tires.

At 14 on HT tire, you risk of getting pop-out (tire off the wheel) under some fast sideway descent by mistake.

1) AT tires it has, 265/70r18

2) I was testing deflators and inflator(dobinsons has to come tomorrow) 

3) core removal is nice(i did it when doing edi desert course), but for 4 tires anyway it will take total 3 mins if you are very speedy and experienced,  so to put deflator on 4 tires in summary is giving almost same result.

Ps. Most probably after 5 drives I'll be removing core

Today when was inflating tires after drive @Davie Chase and @Gary F were shocked when I said 45psi, but I took that number not from fantasy, maybe wrong, but.. my previous tire size was 265/70r18 and new one LT285/65r18

So here pressure-calculator you can calculate, when you change tire how you should change pressure, on OEM tires it was 35psi, but on LT tires which are wider its showing 46psi equivalent
