speedo/mpg

i just put 30" tires on. if i didn't reprogram my PSOM will is show me getting more or less miles? ex if i actually go 100miles will it show that i went 90 or 110. also, how will it affect my speed. if im actually going 60 will it show slower or faster?

thanks,
Ryan

an easy way to find your speed is to get someone with an unmoded vehicle to go 55 and you follow and see what your reading is. same with 35 and 25. helps alot. i put 36's on my old truck and it was off by about 10miles an hour.

was slow. mine read about 45 when running 55. bigger tire= more distance around the outside=less rotations to achieve the same speed.

30" tires probably won't throw the odometer off my much... It may have even helped it.

Know anybody with a GPS you could borrow? That may be the easiest way to check your speed.
