BodybyFisher Posted May 1, 2008 Report Share Posted May 1, 2008 Yesterday, I had to take a 260 mile trip to Manaloken, NJ. With gas prices skyrocketing, I decided to run my tires hard, so I put 37 cold in the front and 35 cold in the rear. I immediately felt the car moved easier, and found that with the 'usual' gas pedal pressure I was flying. During the trip with mixed driving, I averaged 51 MPH and got 23.3 MPG, which I thought was pretty good given my historical performance. I will admit that I did not push it, but I was not driving like grandpa either, my speed never exceeded 70. Be careful NOT to exceed the MAX air pressure on the side walls!
