Which is something that eludes me: should you go by the recommended
psi on the tires or on the vehicle?  And what about plus sizes?  I
read the "Tyre & Wheel Bible" online and he basically says "jack it up
as high as it can go" for better fuel economy (I think he had it at
40psi, the max of the recommended psi).  I've never quite figured out
what the proper pressure should be for street and/or track
applications.
