tpms sensor & rubber valve stems

[Occupant5143]

I've been having problems with valve stems failing. See if you can spot the problem here.
I need to order some metal stems.

It may very well what we can't see. One possible problem could be wrong size diameter hole size of valve stem. The tire may have the 0.453 dia stems in a 0.625 hole, which will sorta kinda work.

I ran into this on an F-250 with 18" rims. Replaced tires and valve stems. Told store exactly what truck I had, still gave me wrong valve stems. Was driving about 200 miles a day. Serious PIA. Took me couple weeks to figure it out. Make a bottle of soapy water (dish soap). Spray it on stems, maybe move them around if you can. Bubbles will show if leaking.

I had same failure at least 3 times. First two rear single of a dually. Last time front right doing 65, blew a brand new Michelin $280 tire to shreds. Discount tire replaced it and I switched all 6 to metal valve stems and Discount installed all for free. Serious about my tires.

I had to learn this the hard way as well. Rubber valve stems can not hold up to the extra spinning weight of the TPMS sensors. Thankfully the TPMS told me I had a tire going down, so no damage. But as soon as I got home, I upgraded to high pressure metal valve stems all around. No problems since.

Change to metal stems, the rubber will not last and will cause leaks. Also balance the tires at the same time.

Notice the scratches on the rim right where the sensor would rub against it if you pushed it over till it touches the rim. That's what happening when the wheel is spinning and the centrifugal force from the weight of the sensor stresses the rubber constantly. Eventually the rubber fails and leaks air.
I have tried to get metal valve stems from two different stores and was told that they would have to be special ordered because they never seem to have the right kind of stems on hand. I found one store in Akron, OH that happened to have one last one which is now on another tire. I'm on the road now so I'll have to order them from Amazon and have someone install them when I'm staying somewhere for more than a couple of days. A decent auto store might have them but I need a stem that bolts in inside the wheel which are hard to find.

Try a tire store, such as Goodyear, Big O or Les Schwab (west coast), They should have them and install at the same time.

Metal bolt in valve stems (with rubber for either hole dia.). Rated over 100 psi.
