Subject:speedometer accuracy
From:Karl Ploessl

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?
