In a just released survey, nearly 3 out of 4 vehicles were operating with at least one tire underinflated. That's 72%!!!!
Underinflated means an air pressure below that recommended by the mfg.

The AVERAGE underinflated pressure was a whopping 6 PSI. This is a very significant percentage!!!

Underinflated tires affect a vehicle's performance and handling--and pose a very large and real safety danger---as seen in the unfortunate issues w. the Bridgestone/Firestone and Goodyear tire issues.

Please check your tire pressures once a week.
Average pressures for 17"--app. 37psi.
16" app. 34 psi.
18" app. 38psi.

Many things affect a vehicles performance and handling,--but tires and tire pressure, proper rotation, and wheel alignments--should all be performed regularly to ensure proper wear and driveability of your tires.
PS. Please check the interior edge of the tires, the most inboard section too---many times wear will occur there, even though the tire on the outside edge appears fine!!!<ul><li><a href="http://www.ronalusa.com">http://www.ronalusa.com</a</li></ul>
