G Rated Tires / Not Max Pressure
In another thread, we're discussing if the dealer gave me the proper valve stems for my G614s. They're certainly not the typical metal stems. The dealer is 260 miles away. So I'm fixing this thing her...

TR600HR and TR801HP (rubber high pressure valve stems) are rated for a maximum pressure of 100psi, or 6.9 bars. A TR416 or TR416S metal valve stem can handle up to 200psi, 13.8 bars.
You may be okay with a 100psi rated valve stem since you won't be running max pressure in those tires. But why take a chance. Go with the Metal clamp in
TR416 version torqued to 24-45 inch pounds.
As a caveat, if you ever install metal valve extenders or an external TPMS system in the future, do not use rubber stems. Centrifical force can cause break or crack the stem and cause it to leak or unseat.
