How to prevent theft of external tire pressure monitoring sensors?
2 Answers
External sensors have relatively weaker anti-theft properties, but nowadays there are anti-theft nuts that require specialized removal wrenches for installation and uninstallation. Detailed introduction is as follows: Disadvantages of external type: External tire pressure monitoring TPMS, with sensors outside the valve stem, is more hazardous. It cannot accurately monitor the internal condition of the tire and doesn't even have the chance to be tested by manufacturers. The externally mounted valve stem type can be easily damaged by human or physical interference. Sensors attached to the valve stem are even more dangerous. Since they can only detect the tire pressure and temperature inside the valve stem, a Tire-Review feature report in the US referred to them as "adult toys." Additionally, the externally mounted valve stem can be easily damaged by human or physical interference at any time. Principle of external type: External tire pressure monitoring works by screwing onto the valve stem and blocking the valve pin to monitor tire pressure. If the owner's tires are not dynamically balanced, over time, air leakage may occur. Moreover, driving for extended periods with unbalanced tires leads to increased tire wear, higher fuel consumption, and greater damage to the vehicle, making their use potentially hazardous.
As an experienced driver who has driven many cars, I know that the external sensors of tire pressure monitoring systems are easy to steal because they are simply clipped onto the wheels and can be unscrewed by anyone. To protect them, my most common method is to install anti-theft screws—the kind that require a special key to remove. They are extremely difficult to dismantle, and a set only costs a few dozen bucks. I also make a habit of parking in well-lit, crowded areas and avoid remote corners. Additionally, I’ve marked the sensors on my car, like engraving a unique symbol, so I can identify them if they’re ever stolen. These sensors may seem small, but replacing a single one can cost hundreds. Losing them not only hurts the wallet but also compromises driving safety—without them monitoring tire pressure, long-distance driving increases the risk of blowouts and accidents. That’s why I recommend everyone take the time to install these measures. It’s simple and gives peace of mind, so you don’t have to worry about theft while driving.
