It looks like NHTSA is requiring a tire pressure monitoring system by Sept 2005, which would put it into the 1st Gen Fed Elise:

Is there one already? I know some cars are using the ABS wheel rotation sensors to measure low pressure by diameter, while some use in-wheel transmitters. Does the Elise have one of these already?

yes, I believe it does

What next, a reminder chime when our cup of Starbucks gets a little low?

Oops... Looks like we had a good thread about it here:

But no resolution as to what the Elise will be using. I imagine if Randy took off the tires and didn't notice/comment on the transmitter boxes then we're getting the Indirect system. Weighs less too.

I like the TMPS Infiniti uses.. the ECU knows the pressure of each tire to 1/10 PSI all the time from radio transmitters in the rims. With the right data connection, you can read this off the bus, even though the car provides only one Idiot Light that says "Your tire(s) is severely underinflated". I like a more early warning.

There is no mention of a tire monitoring system in the owner's manual, and I haven't noticed anything about one on the instruments.

As far as I know, the Elise does not have a tire pressure monitoring system.

From page 117 of the manual:

"Please note your car is not fitted with a low tire pressure tell tale lamp so it is especially important that you regularly check the tire pressures."

well that settles it

The Elise does not have a tire pressure monitoring system but just yesterday I heard on the news that a new federal requirement (I believe starting 07) will require all autos to have this. It's in response to the problems with the Ford Explorer rolling problems which was being blamed on the tires. Projected added consumer cost is somewhere around $110.00.

It's just like the federal government to require all vehicles to have this device because of one brand of vehicle which is a rolling death trap. Instead of improving the suspension of vehicles,they let you know when your tire is flat so that you have one second to kiss your arse goodbye. :shrug:

So instead of expecting people to check their own tire pressure the govt will legislate a device to do it for us. Pretty soon they'll be telling us when to eat, sleep, have sex.........

Individual responsibility apparently is moving further and further away here in the good ole USA.

The funny thing is, they will allow the systems that detect a low tire by the differences in the rolling diameters from one tire to the next. Of course, if your tires all get low evenly, the system will think every thing is all right.

One of our managers hadn't checked her tires in about a year. Her husband would check them visually, and since they all looked the same, everything was all right... Even the Mercedes dealer didn't bother to check the tire pressures when the car was in for service.

Finally some guy at a gas station checked them for her, and all four tires were at about 10 psi...:no: She had to learn how to inflate tires, because she had never done that before. :huh:

I gave her a spare digital tire gauge that I had, and every time I see her I ask her if she's checked her tires...
