    Recently bought a 2018 Tacoma Double Cab 4wd. Lifted it and put 20" tires and wheels on it. Speedo is off
    5 miles per hour. How can I fix it?

    Take it to a dealer and pay them to recalibrate it. I remember reading someone doing his and they installed something and it caused more issues than it was worth and they ended up taking it out and just doing 5mph slower.
    It’s also only 5mph faster when you are doing 70mph. When you are driving around town it’s only 1-3mph. Just do the speed limit and you’ll be fine.

    Welcome to the forum. Like @OR17TRD said, have the dealership do it or just compensate your speed

    No dealerships in my area seem to offer that service.
    My lady’s uncle is a master mech at a dealership confirmed it.
    Maybe it’s just Orange County though.. I’ve called them all.
    Triggers my OCD when I know my mpg is probably not reading right..

    Quit running those red lights and keeping your foot in the peddle and it’ll probably improve. Lol

    That's the price you pay for having 285s

    It’s stopping at the red lights and then having to go again that’s making it worse. If I hit the lights green I can average 15-16 mpg.

    It’s the E 10ply that is killing it. Haha. I’ll be looking at getting C 6ply next time.

    Yes they are. I got a good deal on them but I’m paying for them in gas. Haha

    @OR17TRD is pretty heavy too. He was around 400+. That may have something to do with it too.
