High tire pressure _prevents_ hydroplaning. By decreasing the contact area, it increases ground pressure and "squeezes" the water out. And 30 psi is _way_ to low for a high-load tire. A loaded car and a loaded "truck" are two different animals. For a load range D or E tire, 80 PSI probably about right. The big killer of tires - especially truck tires - is heat. And the quickest way to get a hot tire is the excess flexing caused by under-inflation. So if you have a load on the tire anywhere near it's max, make _sure_ it's not under-inflated. I have had numerous vehicles hydroplane numerous times without a catastrophe. Just like I've had a car slide on ice without turning sideways. I have also experience a couple blowouts. NOT fun!!! I'm with Peter. From my experience, risk from a blowout is much greater than hydroplaning. -- Philip _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
