Re: Site for tire sizes and spedometers
How about if I have 265/35/18 up front and 285/35/18 in the rear. Which one is the one that'll effect the speedo. I get 1.5% to fast with the 265 and 0.7% too slow with the 285. Do I just subtract on from the other. If that's the case 0.8% isn't too far off from factory wheels.
