    It got colder here and my tires dropeded 4 or 5PSI. My milage went from 20 to 18-18.5. Does that seem like a cause possibilty? I am running 31 PSI now on my Double Cab. The pressure was at 25-26PSI. I did not change driving habits.-Rich [​IMG]

    Tire pressure can definitely effect your mpg, I suggest running just a few psi under your tires max psi. I have BFGoodrich Allterrains and the max psi is 50. I usually run about 45, I've got about 3k on them and they are wearing even, however they have hardly worn at all though these things wear like iron.

    I agree.... I experienced a similar increase with tire pressure/mpg.

    It hasn't been as noticable on other vehicles I drive - but on the tacoma it was. I was running at the recommended 29psi ever since I bought the truck back in March and I was consistantly getting 17.5-18.5mpg. Just about a month ago - I raised it up to 32psi and the first tank I got about 19.5mpg.
