TYRE PRESSURE WARNING LIGHT: WHAT IT MEANS AND CAUSES

TYRE PRESSURE WARNING LIGHT: WHAT IT MEANS AND CAUSES

Tyre pressure warning lights are often seen on the gauge cluster of a vehicle's dashboard. These lights are frequently amber or yellow in colour and simulate a tyre cross-sectional area with an exclamation mark or the initials "TPMS." The term TPMS refers to the vehicle's tyre pressure monitoring system. When the TPMS detects low air pressure in one or more tyres, this little indicator light illuminates to inform you.

This indicator will illuminate once the air pressure in one or more tyres exceeds the acceptable range. Because the optimum safety and performance advantages of tyres are realised within a certain air pressure range, measured in psi, the alarm light may flash as early as 10% below the acceptable pressure—long before the low pressure is visible to the human eye.

Many of the most modern tire-pressure monitoring systems will notify drivers when a tyre is out of range or will display actual air pressure within each tyre, including spare tyres in some cases. Buy Tyres Bryn for better performance.

What Causes Tyres To Lose Pressure?

Even though there are no leaks or punctures, all tyres automatically lose air pressure with time. Air may travel via the framework of the rubber at a pace ranging from 1-3 PSI (pounds per square inch) every month. The pace at which this occurs is determined by the tyre's manufacture and model. The speed at which air departs varies according to the rubber mix.

This phenomenon is typical and would occur regardless of what you do, therefore it's critical to check your tyre pressure at a minimum once per month or two. Although 2 months of tyre pressure loss might not seem like much, poor tyre inflation could cause tyre cupping, which could also ruin your tyres in the worst-case scenario or reduce your gas mileage in the best-case scenario.

It is worthwhile to investigate them. If you ignore it for six months or over, osmosis could result in a loss of 6-18 PSI, that's more than adequate to set off your tyre pressure warning light or force your tyre to blow out.

The Causes Of Tyre Pressure Warning Light

  • Weather Temperature Transitions

If you've ever returned to your car after a chilly night to find the tyre pressure warning light lit, it's most likely due to an overnight drop in air temperature.

Cold air is denser than warm air. Warm air, on the other hand, contains fewer molecules but much more energy, allowing it to exert more pressure on its immediate surroundings. Cold air, on the other hand, contains little energy and hence cannot generate as much pressure. As a result, as the temperature drops, the pressure applied on the inner surface of the tyre lowers. It's always a good idea to double-check your tyre pressures in this case, especially if the cold weather is still on the way. If, on the other hand, you merely checked the tyre pressure recently, driving your car and obtaining some warmth in the tyres should take care of the problem.

  • Something has got into your tyre

Nothing is more frustrating than walking outside to find a nail in your car's tyre. Sometimes you're lucky enough to locate the nail early enough to fix it, and other times you're not.

If you see the tyre pressure-lowering frequently, you should properly check the problematic tyre. Also check if there are any pins, nails, or sharp items protruding out of the tread. If you find something like that in your tyre, you must call your local service facility right once, as they will be able to repair or replace your tyre.

  • Sensor for flawed TPMS

While this isn't typically the first thing that springs to mind, it has always been a problem for drivers who can't figure out why the light is still on even after filling up the tyres to manufacturer specifications. A faulty TPMS sensor may frequently flicker briefly before becoming light. Monitoring tyre pressures is a good idea since it is safer in general.

If the problem persists, drive your car to your local store, where a knowledgeable specialist can address the issue for you.

  • Poor tyre pressure

When the tyre pressure warning light activates, it typically indicates that the tyres are underinflated. Manufacturers often set the TPMS on their cars to glowing when the pressure falls below 75% of the required criteria. As a result, you frequently have enough time to fix the problem.

Under-inflation of the tyres causes uneven and faster tyre wear, increased fuel consumption, and poorer driving control. To ensure your safety when driving, check your tyre pressures regularly. The TPMS light shows that your tyres are just 25% underinflated. This is risky, especially if you're towing a load close to the vehicle's maximum capacity. There is a greater possibility of tyre failure, poor handling, and higher tyre wear and tear. As a result, your fuel efficiency may suffer. When you re-inflate your tyres, the TPMS light will turn off when the tyre returns to its original pressure.
