I would question that theory...

When I had the new wheels fitted (day 4) the alert went off about 2 kms up the road. I did the reset trick thinking maybe the pressures were different but no change. Most of these systems work using a wireless pressure monitor in the valve - this is why changing wheels and tyres meant I had to disable this feature.
