Now I have to decide if I want to put up with the rougher ride and wear out the center tread on the tires versus the extra mpg.......decisions, decisions.

As badly as I've become obsessed with getting 20 out of this truck, I think I'll drive it with 40psi in the tires for a while and just see how it goes.

My tires have a sidewall rating of 44psi. I run the max in the front and the last time I measured tread depth, I was even all the way across at 8/32. Good even wear. The rear I had to lower to 40 psi because of the center wear. At about 20000 miles the inside 2 treads were 1 32nd lower than the outside. I just checked a couple of weeks ago and it had evened out to 6/32nd all the way across. The 2 inside were still just a "line' lower than the outside. At 30,000 I will rotate back to front and see how many more miles I can get out of these Michelin tires.

I have tried many of the mileage tricks and tried to figure out what works the best. Bottom line for me is, I bought the truck to use, I want it to look good and perform well. If it costs me a little mileage, I'm alright with that. I knew going in that the mileage wasn't going to be as good as the family mini van. Even though the mileage isn't as good, it is still my vehicle of choice. I drive a company owned work truck so unlike a lot of you fellow F150 owners, I don't get my F150 fix every day unless I go out in the evening. Which brings up another thought. Since it isn't a daily commute vehicle, that may be part of the reason I am not as concerned as some of you about the mileage.
