The importance of maintaining proper tyre pressure

Proper tyre pressure is crucial for the performance and safety of any vehicle. Maintaining the recommended tyre pressure is essential when driving a compact car, an SUV, a ute, or a heavy-duty truck. Correct tyre pressure ensures optimal contact with the road surface, improving traction, handling, and braking. It also helps distribute the vehicle’s weight evenly across all tyres, reducing the risk of uneven wear and premature tyre failure.

Tyre pressure affects fuel efficiency as well. Underinflated tyres increase rolling resistance, which requires more energy from the engine to move the vehicle forward. This results in decreased fuel efficiency and higher fuel consumption. On the other hand, overinflated tyres reduce the contact patch with the road, leading to poor handling and decreased fuel efficiency. By maintaining the proper tyre pressure, you can maximise fuel efficiency and save money at the pump.

Furthermore, proper tyre pressure contributes to a smoother and more comfortable ride. When properly inflated, your tyres absorb road imperfections better, reducing vibrations and improving ride quality. This enhances the overall driving experience and reduces the wear and tear on your vehicle’s suspension components.

How TPMS works and its benefits

TPMS is a sophisticated system that monitors the air pressure in your tyres and alerts you whenever there is a significant deviation from the recommended pressure. There are two types of TPMS in the market today: direct and indirect tyre pressure monitors.

Direct TPMS uses pressure sensors mounted inside each tyre to measure the pressure. These sensors send real-time data to the TPMS control unit, alerting the driver if any tyre pressure falls outside the specified range. Direct TPMS provides accurate and reliable tyre pressure readings, making it the preferred choice for many vehicle manufacturers, including Toyota.

Indirect TPMS, on the other hand, does not use pressure sensors. Instead, it relies on the vehicle’s anti-lock braking system (ABS) sensors to monitor tyre pressure indirectly. Indirect TPMS measures the rotational speed of each tyre and compares it to the vehicle’s speed. If one tyre rotates faster than the others, it indicates a potential decrease in pressure. While indirect TPMS is less accurate than direct TPMS, it can still provide valuable information to the driver.

Now that we understand how TPMS works let’s explore its benefits to your Toyota.

Benefit 1: Early Warning System

One of the primary benefits of TPMS is that it serves as an early warning system for tyre pressure issues. Whether it’s a slow leak or a sudden loss of pressure, TPMS alerts you immediately, allowing you to take corrective action before it leads to more significant problems. This proactive approach helps prevent tyre blowouts, which can be dangerous and costly.

Benefit 2: Improved Fuel Efficiency

TPMS plays a crucial role in improving fuel efficiency. By ensuring that your tyres are correctly inflated, TPMS helps reduce rolling resistance, which translates into less work for your engine. When your engine doesn’t have to work as hard, it consumes less fuel, resulting in improved fuel economy. According to studies, properly inflated tyres can improve fuel efficiency by up to 3%.

Benefit 3: Extended Tyre Lifespan

Another significant benefit of TPMS is that it helps extend the lifespan of your tyres. Underinflated or overinflated tyres wear out faster and unevenly. By maintaining the optimal tyre pressure, TPMS ensures that your tyres wear evenly, maximising their lifespan. This saves you money on frequent tyre replacements and reduces the environmental impact of tyre waste.

Benefit 4: Enhanced Vehicle Performance

Proper tyre pressure is vital for optimal vehicle performance. When your tyres are properly inflated, they provide better traction, handling, and braking capabilities. This translates into improved cornering stability, shorter braking distances, and enhanced overall vehicle performance. Whether driving on wet or dry roads, maintaining the proper tyre pressure with TPMS can make a noticeable difference in your Toyota’s performance.

Benefit 5: Safer Road Travel

Safety should always be a top priority when it comes to your vehicle. With TPMS, you can rest assured that your tyres are always in good condition, reducing the risk of accidents caused by tyre-related issues. TPMS alerts you when the tyre pressure is too low or too high, helping you avoid potential blowouts, tread separation, and other tyre failures. By investing in TPMS, you are investing in the safety of yourself, your passengers, and other road users.

How a TPMS works in Toyota vehicles

The ideal Toyota Corolla tyre pressure is 32-36 PSi (pounds per square inch). This is also the case for most Toyota vehicles. However, it’s always best to check the owner’s manual, the sticker on the driver’s side door jamb, or the inside of the fuel filler door for the precise tyre pressure specifications for your vehicle.

To maintain this tyre pressure, a TPMS commonly works like this:

  1. Sensors – TPMS uses sensors to monitor the air pressure in each tyre. These sensors are located in or inside the tyre’s valve stems.
  1. Alerts – Suppose the TPMS detects that the air pressure in one or more of your tyres is below a certain threshold (usually around 25% below the recommended pressure). In that case, it will trigger a warning light on the device. This light is generally shaped like an exclamation mark inside a horseshoe or resembles a tyre with an exclamation mark inside.
  1. Check and Inflate – When the TPMS warning light illuminates, checking the tyre pressure in all four tyres using a tyre pressure gauge is essential. If any tyre is underinflated, inflate it to the recommended pressure.
  1. Reset– After inflating the tyres to the correct pressure, some Toyota models may require you to reset the TPMS system to acknowledge the new tyre pressures. This process is usually explained in the owner’s manual.
