Just a note on lower tire pressure in the rear of a truck. Be careful your first time out on wet roads. Low tire pressure and wet roads can bring the truck around on you. You do loose traction if you are under inflated.
The more PSI you have in a tire,the smaller the contact patch becomes. As the contact patch becomes smaller you lose traction.
A tire with 40 psi will have better traction on wet roads than a tire with 70,80 etc.
The less air pressure you have in a tire, the less side wall support you have. Go around a corner and your tire "flexes" and will loose traction.
Tire pressure is not just all about the amount of tread on the ground, it supports the side walls as well.
Less weight, less sidewall support is needed. That is why they have weight/inflation charts.
Running lower pressures based on weight on tires is perfectly acceptable!
