It has been discussed quite a bit already.....try here.
I like 40psi all around. Just don't excede the "max" number listed on the sidewall. I've used a formula of "max pressure - 10%" as a starting point for most tires. The 32f/34r (I think that is the Honda recomendation) seems a bit low. I've noticed in reading about the subject many times here, that 35 all around is very popular with most E oners.
