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 |

Of course, we are making a basic assumption:
That 50 years ago the speedometer were GPS accurate to begin with. They never were..plus the well known practice of having slightly optimistic gauges vs 100% accurate to account for period correct tire size availability. If I.. maybe I've just settled fir being 10% high with my 195/60 14 vs 185-14s! |
