Our speedos are not accurately. That's why most that top end race use GPS. You speedo will probably indicate faster then you are probably traveling. Some can be off as much as 10 or more MPHs.
My Speedo is about 2 MPH over during highway speeds of 65 to 80. It gets worse the faster I go.
Not necessarily, the only thing that ultimately impacts the speed reading is the circumference of the tire.I am also running 19" Wheels which will also throw my Speedo off a bit.
