Speedo correction

I GPS’ed my 08 and with the 255/4519’s at 741 turns per mile the speedo matches the GPS for MPH. Was 3% low before.

so if you want the speedo to be correct check whatever tires you are considering revs per mile

The 235/50r18’s were 762 revolutions per mile versus 741 on the 255/45r19’s
