Valve Stem for 110PSI G Rated Tire

Must have been Discount Tire (America's Tire in California). I just had a set of Michelins put on the truck and asked for metal valve stems as recommended by the manufacturer of my TPMS due to the weight of the sensors. Their response was almost verbatim the response above.

And, yes, the Goodyear G614s on our previous MS came with metal valve stems, and when they were replaced at a Goodyear tire store, the replacement valve stems were metal as well. Everything I've seen says the rubber "pop-in" valve stems are limited to 80 PSIG (LRE). Otherwise, they're prone to "pop OUT"!

From the Discount Tire website:

Valve Stems

Valves stems are included with the purchase of any tire. When replacing the wheels only, valve stems must be purchased.

A few things to consider:

Valve stems are responsible for keeping your tires inflated, and allow you to add or subtract air pressure.

The diameter of passenger car and light truck valve stems are a standard size that fits virtually every wheel.

Valve stems come in both rubber and metal varieties. The valves we provide are rubber with a protective chrome sleeve and metal cap.

A common myth is that the valve stems never need replacing. The rubber in your valve stems dries and cracks in the same way that your tires do. Valve stems should be replaced at least as often as your tires.
