We had an 87 Accord, rode on 185-70-13s. We put on a new set of good tires, inflated them at 26 psi, which was the Honda spec, and they wore out in less than 25K miles! Next set of tires, we kept at 32 psi (cold inflation max was 36 psi), they lasted more than 40K miles. Still on the car when we sold it.

Honda is a great manufacturer as we all know, and most of their factory recos are sound, but two aren't: tire pressue (too low)and oil change intervals (too long). For our 02 Accord V6, the manual says 30 psi. Cold psi max on the sidewall says 44 psi. A family member is manager of a tire shop, he told me to keep these tires (the Michelin MXV4+) at 40 psi. I am doing so and we're getting excellent highway MPG and good handling.

I would run tires on any Honda or Acura at psi higher than the manual and lower than the cold max rating. We plan to keep our tires at about 4 psi less than the cold rating for the long term. I don't mind the firmer ride.
