Is it true that brass tire valves last the life of the vehicle?

In Florida, I'd imagine the Sun would eat the rubber valves.

In Michigan, I'd imagine some Detroit Democrat porch pirate would steal the brass valves for scrap value.

It's probably true, but on the other hand, they will probably replace them when they replace your tires anyway. Tires sadly do not last the life of the car.

That's true although again they don't need to last all that long.

I have mostly had tire valve failures where corrosion causes the valve to stick open partially and creates a slow air leak. Metal tire caps help mitigate that problem. But then, I change the tire valves every year or two when I change my tires.

I only know my experience. I've owned about 25 cars over the last 63 years. Number of tire valves replaced: 0

I always considered the $5 or so charge for 'replacing the valve stem' when buying new tires was a scam, and thought it might be over with the new TPMS stems. Not so. Now there is a $5 charge for rebuilding the TPMS unit.

Even if the valve is brass, it still has to connect to the rubber tyre, so there is still the supposed flexing point anyway!

Yep. I have never heard of a tyre valve failing on any car driven by myself, or those driven by family, friends, or company cars.

It may of course depend on the environment you driven in. Very low or high temperature *might* affect the rubber, as may things like salt water (whether that is driving through it or simply living near a beach and having tiny spray doroplets in the air), off-road driving, etc.

No doubt it can also happen occasionally due to faulty manufacturing or repairing of the tyre.

The best bet would be to ask a local expert around that area - other tyre shops, the Automobile Association, etc.

There is no connection with a tubeless tire, The vavle stem mounts on the rim.

OTOH, you can cut off a rubber valve stem with dykes. You need a bolt cutter for a brass stem. Some people aren't satisfied with just pulling out the cores and throwing them into the weeds.

A month after I bought new tires one (or more) of the TPMS units failed. They were 10 years old, like the car. If I'd known about their

It still needs an airtight connection to the actual rubber tyre, otherwise you wouldn't need the valve at all.

I have yet to find any silly tyre pressure warning system that actually works. My mother's old VW Polo used to constantly complain about tyre pressure, despite being nothing wrong with the tyre. Even VW themselves couldn't work out why and their only solution was an expensive sensor replacement - she instead simply replaced the car.

There are similar problems with most of the other pointless gimmickry that manufacturers now add to their cars. :-( Thank goodness my own car is over 30 years old and doesn't have any such silliness.

I have never seen a rubber tire valve fail except in fires, accidents, etc. The valve cannot flex like an arm since the tire does not go up and down or sideways back and forth very much. Tires go round and round.

Uh, no.

For modern tubeless systems the tire bead seals at the rim bead, as described in the 1898 Michelin patent. The valve is elsewhere in the rim and doesn't interface with the tire at all.

You're one of those people I wouldn't trust with a screwdriver.

In the winter I switch to another set of wheels with studded tires that do not have sensors. My brain whips out the figurative piece of black tape. I may notice if it's flashing but it doesn't do that for long before just staying on.

They were Ok when they worked. I filled the tires to 35 lbs and I got a warning when one of them went down to 24 (later on 28, but not for long). Good enough.

AutoZone prices vary between $6 and $1400 -- roughly. More reading is necessary, but I doubt it's worth it. I have a cute little electronic gauge which also talks and the $35 Harbor Freight pump. Reasonably convenient, although the rechargeable ones seem pretty slick. Nice to not have to keep unscrewing the hose because the gauge on the pump is flakey. Why don't they have quick-release connectors like bicycle hand-pumps?

I used to think that, but I got hooked on AC and electric windows. And then I decided I liked the push-button on the key to unlock the doors. The electric thing to adjust the side mirrors is pretty neat too. F*ck, I've gone over to the dark side.

Don't forget remote start when the temperature is very high or low.

I don't keep a car past the warranty period. I did have a bit of panic today. suddenly the SiriusXM radio cut out. Came back after 10 minutes so I survived the ride home. It was their glitch. .

This is the type of person that caused auto owner manuals to caution about drinking the battery fluid .

Our 27 year old 4Runner has all that (fob for remote locks , I don't use it) . What it doesn't have is internet connectivity and GPS spying . And I can work on it without permission from the dealer .

Sorry, that seems stupid. SoCal is never that cold and the car takes maybe 5 minutes for the AC to be fully cold, and I'm not willing to just let it sit idling for that long. I'm tough. I can deal with s*it.

Wow. I don't get rid of a car until it won't work any more or won't pass the smog test. I've always been really good at picking used cars, but now I'm not so sure -- but I couldn't see a reason to NOT buy the

when I'm using it, but not enough to spend $250 or so.
