    Just put new wheels and tires on my 2008 V6 Tacoma. Nitto 285x65xR18. I noticed a huge lose of power and my gas mileage when to crap. I had an idea this would happen when the new tire were put on. I have a k&n intake and a flow master 40. What else is there I can do to get some mileage back and hp. My tacoma is also a 6 speed manual too. I don't know if that makes any differenace. I need all the help I can get weather it is a programer or something please help.


    Sorry here's some pictures of my ride.

    Welcome to TW!
    You will have to re gear to get the performance back in check. 4.56's would be a good ratio with that size tire.

    Regear to get back stock ratios but that's expensive compared to the gas savings.

    As many stated if you want power back you will have to regear
    Your tires are almost 33" in diameter so your milage difference beetween your original dunlops is 4% so you loose 1 mpg just for the difference in tire diameter. More if your tires are wider. So not necessary your mileage is bad some of it is your mileage reading being off. ;)

    Good point your speedo and odometer will be off don't forget to calculate that in. One more factor that could have hurt your gas mileage is also the increased weight of the tire although you may not think there's that big of a difference it's rotational mass which is worse than just dead weight in the truck.

    Maybe swap to full synthetic oil if you haven't already...as that might help a little.

    Other than that a regear is in need :)

    Mods so far: Tube steps from toyota, Bed extender from toyota, Spare Tire lock, Sound System Makeover, Tacoma All-Weather heavy duty rubber floor mats.

    Sh!t man I dont think the exhaust and intake really help with mpg period.

    I was avg 14.8mpg with my 285s and 3inch lift with flowmaster 50 no intake. However I drive at 80mph on the freeway and around 2250 RPMS

    I drove this weekend cruising at 70-75 around 2000RPMs and I averages 17mpg on my tank

    I have an automatic

    Case in point dont gun it and enjoy being in your truck longer :)
