Good morning everyone, I've been trying to adjust my speedo to go with my tires. I have set the ratio and the tire size for what I have but my speedo is still 3 mph fast. Any ideas or direction will help.
Thanks

Re: tire ratio speedo problems
don't go by sidewall numbers.. you need to actually measure your tire from the ground to the top of the tire, and then enter in that inches amount for the tire height..
as long as it's within 1-3mph of a gps, it's fine..
if it's more than 3 mph off, then re-adjust it until it's closer..
