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.
I lowered the pressure in mine down to 60, but at some point if the truck has any type of ABS system on it, the lower tire pressure can mess up hard braking. So there is a trade off point. I had a friend who almost lost his SRW due to low tire pressure.
Just my .02 cents I have learned over the years. Tire pressure can play havok on the handling of a truck or car.
