My odometer is underreporting by at least 1%.
Yesterday I took a trip that both Google and my TomTom said would be 83.1 km long.
Ended up @ 82 km dead on the driveway.
I see the same pattern on my commute: the odometer reports about 0.5 km less than the GPS shows for 36 km.

Car has the original 185/55/R16 tires for 15,000 km. Same with the 175/65/R15 winter tires.

I did add liters to my fuel log for using a fuel pump that is off. Should I now also add some kms for my underreading odometer?
When precision and vanity go hand in hand, should I give in?
