How often do you have a pinch flat?
Have you inflated your tires to something nearer the top end of what is shown on the tire sidewall. If you do you may find that the mileage will be very close to correct using the 2070 number. If you want to run your tires that soft (35 psi) maybe you should do a roll out measurement. That will give you a more accurate number to program into the computer.
