my tires are at 50psi and are rated 51psi. from 35 psi i went to 44 and picked up a little over 1 mpg. i went to 50 psi and saw another 1 mpg. in a 17 city epa 4runner that drives 90 percent city thats a huge gain. i know im getting at least 2 mpg more with 50 psi.
my in car mpg gauge read 16 to 17 mpg before eccmodder and i got it up to 20 mpg before i started logging my mileage on ecomodder. if i drove more highway miles i guarantee you id be pulling 25 mpg in this car but with only a 4 mile commute to work on all 35 mph flat roads in city driving im happy with a 5 mpg gain since february.
with 90 percent highway driving on a road trip in august i pulled over 27 mpg in a 22 mpg epa highway rated car with no mods other than psi and p&g and no instrumentation (scanguage is coming for christmas).
pump those tires up boys!
