Good thing I have a backup. The block around my house has been measured at 1.1 miles with my car and my last bicycle with a speedometer cable. Just make a trip and note the difference!
thanks again
Not sure about your calculator. 82.25 x 25.4 = 2089 (fwiw)
Tire pressure should be normal before doing the rollout check.
