Before the advent of TPS, drivers had to rely on manual tire pressure checks, which were often neglected or forgotten, leading to potentially dangerous situations on the road.

The origins of TPS can be traced back to 1988 when John Sommers, an engineer from General Motors (GM), developed the technology. It was first used on select 1992 Cadillac models, and since then, TPS has become increasingly common in modern vehicles worldwide. Some countries, such as Australia and Japan, have made TPS mandatory equipment for new cars.

The TPS technology uses sensors mounted in each wheel well to measure tire pressure information, which is then sent to a control module. This data is analyzed to detect when there is a problem with one of the tires, such as low air pressure or a puncture. The system alerts the driver through a warning light on the dashboard, enabling them to take prompt action to prevent potential accidents.

Over time, TPS technology has continued to evolve and improve, with new features being added periodically. For example, some vehicles now come with automatic tire sealant injection kits that can repair small punctures on the move without requiring the driver to stop for assistance.

TPS has proven to be highly reliable, with most manufacturers offering warranties of up to five years on their systems. In addition, various aftermarket TPS systems can be installed in older vehicles that don't come with TPS as standard equipment.

Apart from ensuring road safety, TPS can also help reduce emissions by improving fuel economy. Properly inflated tires have lower rolling resistance, resulting in less power being required from the engine to move forward and lower fuel consumption.

Furthermore, TPS can help detect other issues with the vehicle, such as misalignment problems or worn-out suspension components. Detecting these problems early can prevent further damage and ensure that the vehicle remains safe and efficient on the road.

In conclusion, TPS has come a long way since its inception in 1988, providing an invaluable asset for motorists today. With its ability to constantly keep drivers informed about their tire's performance, TPS has significantly improved road safety and reduced vehicle emissions while helping detect other issues with the car. As technology continues to evolve, it is likely that TPS will continue to improve and provide even greater benefits for motorists in the future.
