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.
The fastest laps I ever had a race car turn had super low pressures in the tires for a bigger contact patch which = more traction.
I was down to 7 psi in the LR 13 in the RR 15 in the RF and 12 in the LF.
This setup does feel sloppy until you get the tire up to temp but it also has the most traction I could find at the time on the tires we ran. This was about as low as I could go without rolling the tire under.
On another note, my dealer aired my tires down on the test drive and aired them up when I took delivery of the truck. It was a HUGE difference in feel. I was wondering if I got the same truck that I test drove! I just took 30PSI out of the tires and now I have my great ride back. :)
