So, compared to GPS, my Speedo is consistently 5mph too optimistic. My tires are 195/65-15. I’ve read in other threads that has shown to be a good size for correcting error.
So, not really wanting to go taller still, is there any other way to calibrate the Speedo? Thanks, Van |

I swapped to a 944 speedo (replaced the cone shaped plastic cover with a flat glass cover).
My 225/50 x 15 wheels and tires are a perfect match for that speedo. (IMG:style_emoticons/default/driving.gif) |
