In general, tire manufacturers will not recommend any tire pressure other than
what the car manufacturer recommends for liability reasons, however I once
spoke with a BFG tire engineer who admitted that tires get their best MPG and
best wear and best traction at the maximum load pressure printed on the
sidewall (ultimate traction on the autocross course is often a bit different).
Car manufacturers recommend different pressures for noise, smooth ride, and
handling balance reasons which may be less that optimum for the tire. (good for
the car vs. good for the tire). (need I mention Firestone?)
I personally prefer the higher pressures printed on the tire.

Subject: RE: Tire pressure
6-packers,
how much tire pressure do you put on your 6'es ? My car is running on
205/75 tyres on the 15" rim.
In the 4 years I owe mine, I have always put more or less the same in as in
my regular car. In a new mnaual that I received recently, tire pressures
for the 185 width tires are indicated to about 1,5 kg/m2 - which is way
less than I usually did (about 2,2 kg/m2).
What do you use ?
Tx.
