I assume you also looked into all the other "tire pressure" threads before deciding on your psi preference, as in for example:
http://www.greenhybrid.com/discuss/s...ad.php?t=10062
and
http://www.greenhybrid.com/discuss/s...ad.php?t=10307

For other folks, however: I certainly do NOT intend my post to spawn yet another long drawn-out discussion about what psi is "right" (we have enough of those on this forum already, thank you), but some of our forum members may be new and may not know about the valuable info already available just by doing a search on "tire pressure"...

'Nuff Said.
