I didn't invent this term but; Bt Wrong. Tyres on that truck have a max rating of about 85psi to carry it's fully rated load. Failure to properly inflate them will drastically reduce their carrying capacity. And I don't give a damn what Mercedes recommends for his Suburban.

Re: [MBZ] Suburban 454 mileage
It's ok to inflate any tire to it's max, or what is required on the
vehicle info plate. When cold.
It does no harm if the pressure creeps up 10% or so when the tyre gets
hot. The tire is designed for that load.
Check with your tire dealers!

For a given tire, the higher the pressure the smaller the footprint and the less likely to hydroplane.

Re: [MBZ] Suburban 454 mileage
Yes. 3/4&1 ton trucks usually have a ten ply tire. That is a load range E. Max air pressure is 80 psi. Most car tires are four ply with a maximum pressure of 44psi. 80psi would be very scary in a passenger tire, both in handling and risk of explosion due to overpressurization.

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
