Ideal tire pressure for gas milage & wear ?
Just curious as to what you guys feel is the ideal tire pressure for gas milage as well as for less wear and tear on the tires ? I have 245/75/16 tires on my truck. Max pressure on the tires is 88 psi. Right now i'm running them all on 70 psi. The gas milage on hwy driving seems to be decent, although the ride is a bit stiff on rougher roads. What do you guys think is best for gas milage based on your experience ? Is 70 psi decent...or should i go higher or lower ?
