Tpms

[fb88]

Can the individual tire's psi be coded to display on the monitor, so that we do not need to manually check each tire?

No.
Our Mazda3 uses indirect method to detect tire pressure.
It is based on rotation speeds of tires thru ABS sensors.
Simply put, a tire w/ lower psi will rotate more revs per distance (smaller perimeter).
There is no PSI values per se.

Still, you'd think it could at least be coded to tell you WHICH tires(s) is rotating faster, so you're not running around checking all four of them.

My husband's Nissan Altima displays the actual psi of each tire. Very nice feature.

Yeah, a number of cars are doing that, the new Dart and I think the new Forte also (not sure). The downside is that you have to have a TPMS sensor in each tire (Hyundai makes them part of the valve stem). And the system needs to know which sensor is at which corner, which needs to be fixed every time you rotate them. Those TPMS sensors usually have to be replaced periodically, and they cost money.

I personally don't care that much about the actual pressure in the tire, but I WOULD like to know which one is the one reading low.

I was looking into other external solution like Tyredog on my current car, didn't pull trigger.

My external solution is a tire pressure gauge.
With modern tires and valves, I very rarely need to add air. So knowing the exact pressure at all times isn't a biggie (for me).

I really don't care about this feature. Happy that Mazda does it this way as I'd hate to have a TPMS light on when my winter tires are on. I also wouldn't want to replace sensors when they go, which I hear is fairly common for other manufacturers.

 

[npaladin2000]

Some sensors are supposed to be replaced every time you take the tire off of the wheel. And yes, that's annoying.

Hyundai integrated it into the valvestem on my last car. Which not only was annoying but when I had a busted valvestem the tire place couldn't get a replacement right away, and I had to put up with a TPMS light until they did.

Mazda's system is MUCH better, but I still think these systems should be telling us WHICH tire is the one with the low pressure.

I just like knowing I don't have to pay 200 dollars or so for a set of new TPMS for when I buy a new set of wheels.
