When I went to 15" wheels on my Syncro (225-70-15 tires), the speedo inaccuracy
went away.� Just by coincidence, the increase in size and change in rotations were just enough to fix the error.

Subject: speedometer accuracy
 

so I finally got a GPS in my van. And what do I notice?
Speedometer says 60 mph and GPS says 45 mph! At 70 (speedometer) the GPS
says 62!
I am running Michelin Agilis 61 in size 185/14 C and it is a Westy 81
aircooled. And it is in Delaware to satisfy Scott.
The question I have: does this discrepancy also affect the odometer?
