Remember to calibrate your distance and speed readings to accommodate what is essentially a change in gear ratios, the wheel/tire being in essence another gear. If you don't calibrate, before and after the swap, it will be tough to know if you got a benefit because of the distance undercount on the odometer.

I plan to switch to michelin defenders eventually. Running down my current tires first.
Calibration might not be so simple on a car with a spring driven speedometer... ;-) I'm not sure what system the odometer uses...
