Download a gps speedo app on your phone. Expect a couple mph difference. Your tires new vs your tires bald will be different speeds. And not all tires of the same size have the same circumference.

+1 on checking it with a speedometer app. I have several free ones on my iPhone and they are surprisingly accurate. If your speedometer is reading fast, you can build one of these...
