Bill,
That is good to know. The only reason I even went down this road is because of my experience with the ambulance units at work having to go thorugh weights and measure checks every year and so I just automatically thought to do it on my truck. At work, I have the mechanics send out each ambulance over to the speedo shop to check the speedo when we first change from the stock tires to Michelen tires. Anyway, when I take it on the speedo check I will let you know how it checks out.
