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 currently have 195/65R15 tires on my 74 and the speedometer is off by 5mph. So when I am going about 80mph on the speedometer, I am actually going 75. 70 is 65 and so fourth. I may end up going with vreds in 165/80R15 at some point as my tires are due to be replaced by age.

A 165 is just too skinny for my taste. FWIW, they’re made in Holland/Nederland, not China… |
