"Mustang TPMS Sensors and Activation Tool Note: TPMS Valve stems are not designed for speeds over 155 mph"
The reason Ford puts this disclaimer on their sensors is because of the rubber valve-stems. The rubber tends to flex and could possibly cause air leaks. Schrader, (Ford's OE TPMS manufacturer) actually makes an aluminum valve stem to remedy this problem. I know a few of our vendors on here actually sell this valve and have encountered this before. You may want to message one of them. Hope this helps.
