I've had 4 immediate flat tires form having my Jeep Liberty metal valve stems broken off when the TPMS's were installed. The TPMS's do stick out beyond the side of the tire. First time I sent the car through a 'drag your car through' car wash and one of the stems was broken off by the guide rail in the car wash. The second was when I was sideswiped and a valve step was broken off. So my rule was, when I quit towing remove the TPMS's when I'm not towing. Forgot to remove the TPMS's last week and went through a car wash. Two valve stems broke off. I'm a really slow learner.
The tire shop replaced the two broken metal stems with rubber stems. Owner said that there were lots of problems with broken metal stems and the manufacturers were not using them anymore. Don't know if that is true but I can believe problems with broken metal stems.
I guess I'll find out if rubber stems are a problem with my TST's over time. Two metal stems and two rubber stems should be a good test.
