I see this thread died quickly, but I thought I'd weigh in.  So far (only
one road trip) I have used the factory-listed pressures on my van, a 1984 GL
that originally had 185-14 tires.  I have 205/65-15 Agilis and tried 39 psi
front and 48 psi rear, which is the regular air pressure.  The van seems to
work well with these pressures, but I'm not sure if I'm going to burn the
middles out of the rears yet.  Any Agilis 15" long-timers out there?
