Three weeks after installing was pulling our 30′ travel trailer with my dually. Was doing 60 mph and got alarm that front right truck tire was loosing air rapidly. As I searched for a place to pull over it went from 80 PSI to 70 then 60 then 50 and 40. I stopped on the shoulder, was lose and uneven. Not a good place to change a tire. Pressure loss slowed dramatically so I limped down the road to a country convenience store. The valve stem was leaking were it inserted into the rim. Swapped the tire on a flat parking lot and drama was over.
Without the TPMS I would have been oblivious until it got really bad. Might have ruined a tire or more or even much worse. Bought this after I bought my used dually, drove it home at 70 mph and later found an inner dually tire was completely flat on that trip. Lucky it didn’t blow. 😀 That incident and the infamous “china bombs” on new trailers had me worried. Now I no longer have to manually check 10 tires each time we travel. Despite the automated alarm capability we keep an eye on pressures and temps on the screen as they rise depending on speed and weather.
The TPMS is like insurance; if it saves you it’s money well spent, if you never need it then you wasted your money. No complaints on the product. Bought after a lot of research. Expensive but worth it.
