'Nuff said.
My 2020 Rogue-displays the air pressure for all four tires.
I highly recommend the below product. It’s a little pump that is powered in the cigarette lighter port. Reads the pressure and pumps it up to the set pressure
I have a pump. I want to be able to know whether I need to pull over in the first place or not.
Being a working minion, I can’t afford a luxury car. My Honda RV-4 has a tire pressure light on the dashboard that basically says, “There has been a change of several pounds in tire pressure in one of your four tires. Get your butt out there with a tire gauge and figure out which one it is. It’s freezing with a wind? Too bad, so sad. I hope you guess the right tire first.” Usually, though, I can tell by the feel of the car which tire is the likely culprit.
Our 2020 Hyundai Ioniq has individual pressure sensors. It’s been helpful as we constantly get flats in this car with the low profile tires and Chicago potholes. We’ve had four or five flats in the last twelve months. The monitor at least tells me if I just have a slow leak or a complete flat and how quickly I should get over, though almost every time the answer has been : 0 psi, pull over now.
Ya know, I’ve read this. But our Sienna just passed 12 years, and I’ve never had to replace the TPMS. So color me confused.
As for OP’s question, my understanding is that TPMS is mandated on all cars built after September 2007. What isn’t mandated is how precise/informative TPMS is. So some vehicles tell you individual pressure; some have a warning light; and I’m guessing that some tell you which tire, without telling you the pressure.
The chirp-when-you-hit-pressure is a nice feature! Someone was having a good day when they thought of that.
I bought one like that. I like that it’s automatic and that you can screw the inflator hose onto the valve, so you don’t have to crouch or bend over the whole time.
FWIW, my 2017 Ford Escape throws up a tire-pressure warning when a tire drops to 25 PSI. While it’s true that it won’t help you determine whether you’re experiencing an immediate pull-over-now event, knowing the exact pressure at the time of the alert has been helpful in my experience.
A 25 PSI tire on my Escape (and I’d think on most all daily-driver vehicles) looks completely normal – it doesn’t look slightly squashed or quasi-flat or anything like that. So, if you get out, can’t tell by looking, and have to check all your tires with a gauge to determine the culprit … odds are you’re experiencing a slow leak.
The 2015 Corvette we inherited when my father-in-law passed away has a menu on the dashboard which will display the actual tire pressure in each tire. Our older cars (my 2012 Mustang, and my wife’s 2007 Mazda CX-7) both have the simple idiot light indicators.
My 2022 Hyundai has a display for each tire.
Same with me. I think it’s 5 pounds and then it alerts. Mine also has the tire fill alert so when I’m filling the tire it shows me and beeps when I’ve put in enough air.
I’d amend this to say “If it happens more than once in a few weeks”. Tires DO leak slightly by nature, and TPMS are prone to triggering when seasons change and it gets colder, too.
More correctly, the are designed to trigger when it gets colder because the tire pressure varies with tire temperature.
My 2021 Mazda3 Premium will display individual tire pressures in the dash display. I can also check it on my Mazda app. The app is super useful – I can also check how much gas I have, check whether the doors are locked, and remotely lock or unlock them
Yeah. It’s not like you should ignore it, because it’s just that the tires are cold. It means the tire pressure is low, regardless of the reason.
Just checked my 2021 Volvo S60 and it only allows you the reset the system at “ok” after manually checking the tire pressure with no display of the actual pressures.
My car uses a passive system tied to the ABS to determine a low tire, rather than an active system with a sensor attached to each valve stem.
My old pickup ('17 Dodge) had a pressure reading for each tire, presented on a square graphic with numbers at each corner. Since forward and rear tires required different pressures (60 .vs. 80), tire rotations caused a series of warnings. Even if the workers remembered to change the pressures, the system refused to believe it for about 10 minutes, insisting on visual warnings and the occasional “Bong - Bong” to alert me.
My new pickup ('22 Dodge) has the same, but with a more fancy display showing “depth” (as though you were viewing the truck from above and behind). Since all 4 now require the same pressure, I assume I won’t encounter the warnings any more. I’ve only got 3800 miles on it, so haven’t rotated them yet.
Wife’s 10 year old Camry just has a single warning. I have to manually hunt down the offending tire if it happens.
That’s a wee bit hyperbolic, now isn’t it, Sam?
Here. Here’s the procedure as described in the documentation that came with my car:
I’ve committed it to memory, and it has saved my bacon more than a few times.
As you were.
Heh. Sounds about right.
I forgot about this. My jaguar app also does this. I can also turn on the heat or a/c from my phone, and will tell me where my car is (Which actually came in handy last week when both the dealer and body shop said they didn’t have it.)
