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 |

Copy all Clay, I've done these calculations. But I wanted to be sure it was my only real option before I replace four relatively new tires for four new tires, ya know?
Anyway, I think I'll test the waters on these new vredestein classic tires. Their 185-15 tire looks like the right one to bring my speedo to w/in 1-2mph of actual. |
