Tyre pressure monitoring systems (TPMS) are in it for the long haul, and you should learn about the benefits and drawbacks of modern TPMS hardware. By learning the pros and cons, you can avoid some of the most common pitfalls that come with this common but expensive technology.
The Benefits of TPMS
There’s one main benefit to TPMS on cheap tyres: it can save your tyres and quite possibly your life. The monitoring system warns you via an indicator light when one of your tyres has less than 25% of the factory recommended air pressure. You’ll learn about a flat tyre before its sidewalls fold over and come into contact with one another, and are damaged beyond repair. By warning of problems well ahead of time, a TPMS can help you save money—and it can keep you safe.
In most cases, tyre pressure monitoring systems work well, and they serve their purpose. However, there are certain issues that installers of replica wheels and tyres should consider when dealing with TPMS.
- They’re not very robust. Most TPMS systems are part of the valve stem assembly. As the stem is installed, the monitor is placed inside the tyre. The system is relatively fragile, and improper dismounting can damage it. Most tyre installers won’t accept responsibility for valve stem or TPMS damage, and replacement can be costly.
- The valve stems are fragile and can corrode much faster than you may expect. The core, a tiny metal piece inside the valve stem, must be made of the same material as the stem itself to resist corrosion.
- If your car is equipped with a TPMS, you should be choosy about who installs your tyres. Ensure that the shop you choose knows how to handle and reset TPMS systems.
- They aren’t standardized. Almost every car maker has its own TPMS system, and most sensors are dealer-installed parts only.
- TPMS has to be reset after replica wheels are moved or a sensor is replaced. It can be difficult to figure out how to reset the system, and most shops have software or books with instructions.
Tyre pressure monitoring systems have their difficulties, but their one key advantage outweighs many of the smaller issues. Many problems are solvable with today’s indirect TPMS that uses sensors embedded in the ABS system. These systems are becoming more common, and tyre techs welcome them for their ease of use.
