    Got these with the car and they have about 75% life remaining on them. I like the ride they have. Can anyone add any feedback on these? I'm a little confused on what I should be running for tire pressure. They hold 51 lbs. max pressure. I have been running 45 lbs.on all 4 and getting about 55 MPG with 80% hwy. Is it better for MPG to max your tire pressure? Will that affect the ride?

    When I had a Gen 2, I found my Fuel Max wanted 38fr/36r for longest tread life.

    I have heard that it's good for handling to keep the front tires 2 psi higher than the back tires.

    I like to run them at 44 psi front (the max pressure for my tires), 42 psi back. It does firm the ride a bit but they sure do roll nicely, as I'm sure you've noticed at 45 psi. Whenever I try 35 psi, I keep thinking they've gone flat! It feels like driving on a (slow) mattress.
