Tire Stem Failures

[Gliddenwoods]

On the road for a couple months and I have had two tire stem failures within a two week period. The rubber stem on both failed with similar 1/8" to 1/4" horizontal failures.

Replacing with steel stems during repairs.

Cooper Discoverer HT3 tires on 2022 Oliver II at 50 psi.

Causes?

*Bad luck, *Tire brand, *Tire age,  *PSI, *Tire Pressure Minder, *Rubber stems, *Mountain curve roads, *Driving speed, *Life...

Thoughts and wisdom?

Do you have TPMS sensors mounted on your rubber stems?  When I got the TST TPMS I also had my rubber stems replaced with metal stems.  That was about 100K miles ago and no problems.  I think replacing your rubber stems is the way to go.  Mike

Oh boy. 

Same year (2022 Oliver LE2) and same tire for me, and I just experienced a tire stem failure a week ago. Didn't think to ask to see the stem after the repair, to ascertain the type of failure. Also I didn't know there would be options on the type of stem to replace it with, but now I feel my other tires might be suspect. 

Right now, my spare (previously un-used) is still on my Oliver -- not sure if that is a good or bad thing. 

I will be watching your thread here for other info.

Prior owner had installed steel valve stems on the Oliver, always been good. When I upgraded the truck with 3rd Gen Dodge wheels, I mounted with steel stems.

Neither stem should fail, unless there is something about the wheel design, how the machined opening for the stem could be an issue cutting into the rubber. Question is, was the stem physically damaged or replaced because for leaking.

If you have a tire pressure monitor added to the stems excessive flexing caused by the weight of the sensors will fatigue the rubber portion. Plus today’s rubber products sometimes seem to weather rot more quickly. I was lucky in that I never had a stem failure in the seven years before I replaced my tires and changed the stems to nickel plated brass stems. In any event, it would be a good idea to carry emergency replacement stems. I carry these that can be replaced from the outside. Even the metal ones can be hit by a rock or other road trash and be broken. Thankfully I’ve never needed to use them!

New steel stems.

Installed on all tires.

$6.00/tire installed.

The journey continues on...

Rim design really has the stems on the edge, sticking out. Got to be careful with the steel ones too!
