Tire Pressure Monitoring System; Do you get details on each tire?

raps101 · 06-19-2009, 09:48 PM

Does anyone know if the Tire Pressure Monitoring System displays the tire pressure of each individual tire like it does on my 350z?

No...You just get a generic warning that one of the 4 is out of range.

nogoodname · 06-19-2009, 10:11 PM

by the time it's out of range...it's probably flat....lol

I don't trust it enough...just check the tires consistently with a tire pressure gauge

raps101 · 06-19-2009, 10:55 PM

Wow thats frigin sucks! Any idea what the range is? Over 40lbs and below 30lbs??? or what?

nogoodname · 06-19-2009, 11:02 PM

i think it's way below 30lbs

Josh@STILLEN · 06-19-2009, 11:13 PM

G35 is 27lbs.. I can't imagine the 370Z being different.. so it's a fine detector, but for a quick leak, no replacing a visual check before you jump in the car..

I'm still kinda torn on the TPMS thing. It seems silly to me to have something stuck in the wheel that upsets balance and makes them add a bunch of weights on the opposite side to get the balance right. And of course it's mainly designed as a dummy light for people that never check their tire pressure.

On the other hand, if I pick up a nail at the start of a long highway drive, I may not notice that I'm 10 pounds low in one rear tire for a lot longer than I'd like, and that seems like a scenario TPMS would help with. Then again I've always faced that risk without TPMS in the past, and nothing horrible has happened (the above scenario did happen, but the tire was fine after being patched). It may come down to a coin toss whether I move them over when I switch wheels/tires.

Anyone have any idea what the update rate is like? If it were a medium-fast leak, would the system notice before you did, or does it only check every several minutes?

My Cadillac used to email me when my tire pressure was low. I just got an email today and I traded the car in a month ago.

That's an onstar thing.

A friend of mine is in Iraq (electrical contractor) - he has me drive his truck every so often to keep things in check...

His onstar stuff notified him that the tire pressure was 2lbs low...lol

So, having looked at the tires, I made them 5lbs high just to mess with him...and to rub off some of the center tread...

You know.. I've had more than my fair share of warning lights.. with my 20's.. seems like a small amount of depressurization is pretty common, at least with aftermarket wheels.. don't know why.

I'd say it's gone off once every 6-8 months for the last couple of years, and always a nice reminder when I get in (more often in cold weather, lower temps) and within a couple minutes of driving I get the warning.. hit the gas station, check the pressures, fill them up and realign.. off and running.

Let's be real.. does anyone actually go through the process of checking pressures once a week? If so, you're probably the same guy who does full details spending a full day cleaning every 2-3 weeks.. for me.. started that way.. after a couple years.. not so much.

It's a neat feature, and I'm glad it's mandatory.. the worst thing that happens is you're irritated when your pressure slips below 27lbs.. the pros are way more.. tire sidewall wear, not realizing a flat, improved gas mileage, etc.

Definitely transfer them to your aftermarket wheels.. beats starting at the light..

Yes, I do, like clockwork. I've been doing this with all my vehicles for over two decades.

This ^. I'm still checking at least once a week right now, but yeah 4-5 years from now, I bet I'm not, unless I'm tracking the car often (as obviously I would check that among many other things before a track event).

OK Josh, since I live a few miles from the Stillen shop, I gotta ask - what cold weather do we get here in SoCal???

The 2006 350 was the bomb here, displayed the actual pressure on all 4 tires, and was very accurate. Don't miss the oil consumption, but the TPMS was great

Does anyone have the manual? can someone post how the Tire Pressure Monitoring System works? At what point does the TPMS light come on?
