Why wouldn't you want to follow the recommendations set up by BMW themselves,
tire pressure
offset & their alignment?
After all, they did pay engineers to do the work that went into deriving those
pressures and alignment
angles on that vehicle? Not to mention test drives by both professional
drivers and presumably
members of the buying public, before finalizing those specs.

See, that's the 'MIBy'ism(More-Is-Better) that I have long since rejected.
I'll admit, I'm a relative
newcomer to the stickers adhered to the door posts of motor vehicles.From 1987
to around 2000,
I inflated my tires to the Max Cold Pressure on them, PLUS A LITTLE! Yeah,
young n dumb you
could say, lol!
But once I discovered what was really on those mysterious placard stickers, it
was an epiphany!
Suddenly, my cars felt like cars again, and I was able to really enjoy
driving, not just bouncing down
the road, hearing the squeaks and groans of my car's body and frame, and
rattling of the suspension
from waaaaaay too much air in tires.
Do I believe in going just a *little* the pressures on the door placard?
Maybe 1-2psi or so, and mainly
in winter. For me, any more than that, and the ride harshens, and the
steering becomes too darty for
me(I prefer some heft when turning the wheel off center).

Re: Bridges - I disagree. Posting weight limits on a public infrastructure
makes perfect sense. But for tires
intended for *consumer* use(not on a Boeing! or a military or large commercial
vehicle)? REMOVE IT.
Why? Simple! Review my young n dumb example above: It's the first thing you
see on a car - the tires! And
that max cold spec is right there. As opposed to a decal stuck on a
relatively inconspicuous part of a vehicle
that your BEHIND is more likely to notice as you swing into your drivers seat!
lol
So yeah, I think words to the effect of "SEE VEHICLE FRAME PLACARD OR MANUAL
LITERATURE FOR
MANUFACTURER-REC. TIRE PRESSURE" would suffice. Along with enforcing the P-
or LT- designation
in the size stamped on the tire: Underscore that info with "PASSENGER(or LIGHT
TRUCK) USE ONLY".
Those modifications to standardized tire etchings might put an end to, or at
least reduce good ol' Murican
MIBy-ism! ;)
