Speedometer help!!
I just bought 35's and i had 285/70 on it before, my speed odometer was like 5 mph off! I have tuner, so I went into the program to change it! I put in 35 for the tire size, now it's 5 mph fast! So I said ok, I'll move it down then! I put 34 in didn't move at all so I did 33 still 4-5 off at 65mph! Am I moving it the wrong way? Maybe I need to put in 35.25 or something like that! Please help
