tire pressure and performance...
i drove my new 2004 maxima SE home a bit ago and thought i had made a huge mistake in my purchase as the car didnt handle nearly as well as i had initially thought (and test drove). i got home and began noodling the problem. here it was: the 18" tires came fully inflated to 47psi from the factory. apparantly, the test drive models on the lot had all decreased the pressure to around 32psi and it made A TON of difference. now my question is...i prefer the handling improvement of the lower psi, but will this not ruin my tires far faster than if they are filled to thier recommended pressure? at roughly $300 per tire, i take this issue fairly seriously, and i hope that someone has some good advice or information on this issue.
