By using a good gauge and checking every few weeks, I have never had a TPM light in the year and a half I've owned the car.

Definitely not ridiculous. I've got one of those pop-out types I've been using for years. I figure it's not terribly accurate, and have considered getting something better. Maybe it's time I did that.

Re: Tire Pressure Monitor

I have a 05 Xfire Convertable, The manual seems to indicate the Tire Pressure Monitor System is standard.
Right? I have never seen the dash (low pressure)light on at anytime. The car had 9000 mi on it when purchased, but I now see there are typical Shrader valves on the stock rims. What's going on? Mileage is
low so, I assume the tires are original. I don't have the required sensors on any of the tire valves.
Questions:

Is the pressure system standard or optional?
If standard, why does the pressure lite never show up, even on start up?
What may be the explanation for standard Shrader valves and no TMS valves? The car is in mint conditon. Everything looks stock and new.
I don't want to spend a bunch of money on valve sensors to find the car doesn't have the system.
I could leave well enough alone, but what concerns me is that the low profile tires don't go down much when low or flat and one could ruin a tire quick by driving on a low tire.
