After doing some research for the Sorento on rotational mass and unsprung weight I came across as discussion on Tire Pressure vs Rolling Resistance.
Tire inflation pressure seems to be another variable that most do not address on a regular basis. I am now running my Sorento and Koup at 40psi and I can say it doesn't have to work near as hard to move the vehicles. What a difference @ part throttle--especially in the higher gears. The car just feels easier to push.
The articles I read said that most SCCA cone racers run this setup on both street and strip. I am sold.
PS: Look at the MAX Inflation Pressure on the side of the tire. In this case I went 9-10psi under the limit for safety. It should be noted that the articles spoke of alignment techs using max inflation Pressure to properly align the wheels.
