They are not readily accessible, and cost a LOT!


Saved me twice already. Note that it alerts at 26 psi, caught me one time backing out of the garage. Chimed and put up the display, went to my RR tire and had a puncture, leaking fast.

No spare really makes you appreciate the system. When you run 35 series tires they ALWAYS look low!

+1 I have 3 female drivers....aluminum wheels ruined from driving on a flat tire cost upwards of $400. TPMS has prevented 4 roadside calls in my family already.

We seem to have little to no flat tire in So Cal.

My almost 300k miles LS400 had 2-3 flat tires in more than 18 years. The last one was more than 6-7 years ago.

My 12+ years old 140+k miles E430 has band new full time spare in the trunk, never use.

The almost 9 years old S2000 brand new compact spare tire was in garage its entire life, in its place is a sub-woofer and a fix-a-flat bottle.

None of my cars has TPMS, and I'm glad that none has it as it's a feature I don't think we need. I can easily check tire pressure once a month or two, and pump up the tires 1-2 PSI when needed.

You are right - the woman thing...
I am now convinced.
But let's please train our kids to be car responsible.
 
I'm sure its a nice thing, but as I pointed out, a light that comes on for when the spare is wonky is annoying. If you ask me, the system needs to tell you what tire is gone bad, and preferably just how low it is. That way you can decide if you need to pull over right now, or if you can limp to the nearest safe spot. Our Camry lacks that, so, as I've already said, I've learned to ignore it--how useful of a system is that?

That said, I'd hate to have it on a beater that I use for dump runs or short trips. On an old vehicle it's just one more thing to break. I wouldn't be the least bit surprised if you'd fail a vehicle inspection if the light was on.
 
Engineers can make the tpms system as sophisticated as you want. How much are you willing to pay for it?

Personally, I think it's enough that the light (correctly) alerts the driver, and tells you to get the tire gauge out and check things further.
 
Doesn't a typical TPMS system has all the hardware necessary to give exact pressure of individual tires? If so, then it is just a question of having a screen (and software) somewhere to display the PSI of all four tires, something like this

Doesn't the Lexus have something like this on the dash? The above picture is from the Acura TL.

Ours just goes to a fault mode: it will blink for a minute I think, then stay on steady. Why should I fumble around with a a code reader (which I don't have) in order to determine what is up? Plus, the light only comes on (it seems) once I'm at cruising speed. I'm supposed to treat this like an emergency, pulling over immediately? I could be on the highway, in heavy traffic. For that which I've proven (thus far) to be a system fault?

Either do the system right, or don't bother... Yes I understand, the average moron hasn't a clue, and most don't want to pay for it. I'm just not the average moron. I still fully believe I should be able to hit a button and have it scroll out any and all trouble codes on some display. How much could that possibly cost?

Are you still laughing with that screw in the tire?



No I had it fixed Friday afternoon at the shop across the street. It was a very long drywall screw.

Nope, just show`s an amber light of the bottom half of a tire.

If a car can tell you which door is ajar, then it should be able to tell you which wheel is low on the tire pressure. Actually, it should be able to tell you the exact pressure.

That amber light might be federally mandated but there is no reason why car makers can not do a better job. I suppose they want to you visit the dealer to hook up the TPMS scanner.
 
^^^Yep, it's just like Chrysler putting copper plugs in the 5.7 engines. Get's a lot of folks back to the stealership every 30k miles. We have a thread on this forum about Hyundai soliciting service that is not called for in the owners manual.

I have actually had a tire dealer try and charge me for a scan tool reset of my TPMS when I had them mount tires I bought online! When I told him it didn't matter, the car will figure it out within the first mile, he said "you'll be back."

I wholeheartedly agree with this statement.

Speaking of morons, no amount of engineering will ever protect those people from themselves.
 
A car could not only scroll out the trouble code, it could even decode and with the help of a smart phone, could give you step by step instruction on how to diagnosis it further and fix it. They could have the entire service manual already on the built-in hard drive.

Seriously, most of the new car's entertainment system has more processing power built-in than the most expensive Snap-On scanner. With the ability to link with a smart phone, in theory, it has the entire internet at its disposal.

But we all have to agree that unless CARB/FED mandates it (commie, commie, commie!!!) it is not happening.

Right.
It should be available, but then we'd be taking work away from their service centers. The mysteries would be exposed.
 
The 'key dance' (3 times on, 3 times off, then leave on) will scroll any set codes in my EVIC display in my car.

Wish they all did that trick!
 
Hmm, not sure my wife would like me doing that while going down the highway!

That still works!?
