That is true and will work.  For many if not most cars upping the  
tire pressure a few psi (<10) will give you better mileage with out  
adversely effecting tire wear and generally improve handling.

If I was paying attention the statement was to inflate to the maximum  
mfg pressure.  If this is the pressure on the tire then it will most  
likely be over inflated.  For instance the tires on the Miata have a  
maximum rated pressure of 44 psi but 30 psi is where the car handles  
well in everyday driving and is several psi above what Mazda  
specifies.  At 44 psi the centers would be gone in no time not to  
mention the loss of road grip under adverse weather conditions.

For our Spridgets finding the right tire pressure is a bigger  
challenge unless you are running bias ply tires where you have the  
recommend pressures that came with the car.  I am about to put new  
tires on the Sprite and have been working with my supplier to try and  
find a reference from the tire mfg that either correlates bias ply  
pressures to radial pressures or pressures by vehicle weight  
distribution, no luck thus far.

Lets start a new thread for tire pressures - what tires and what  
pressures are you running ?  If you want to send them to me I will  
put them together in a single sheet for the list.
