My odometer is off by about 6-7 mph at about 65 mph. I have 245/45-16's. I know it should be off by 1 or 2 mph. But 6-7 mph seems to be to much. Does anyone have the same problem? If so what did you do to fix it?

 

went back to 225s but i think u can get it recalibrated which is PITA. Dont know about cali but RP in dallas does it.

 

i got same size tires and mine is off 1 or 2mph. When I passed by that Police radar thingy it showed 38 and i was going 40.

 

Your size tire should have very close to the stock circumference. I believe you should see at most the 1-2 that you mentioned in your post.

 

idk, i always say im going 60mph but the cops seem to think im doing 90

jk, i do think its about 5-10mph off or so though when i switch out my rims/tires
