Good Tread on Tyres Ensures Good Traction During Road Contact
It may be quite aggravating when tyres continue to lose air. Especially if there are no visible causes, such as a puncture or rip. Then you pay a few hundred dollars to get your car tyres changed. Before we get there, here are a few things to think about.

Changes in Temperature
Temperature fluctuations might cause your tyre pressure to change substantially. For every ten degrees Fahrenheit change in temperature, one to two pounds (PSI) drop. Thus, if the temperature drops by 20 degrees Fahrenheit over a cool fall weekend, your tyres might lose 4 PSI. The PSI measurement may be misleading after a several-day summer heat wave. And if your tyres are old or damaged, they will be more susceptible to these oscillations.
Before you receive a replacement, try inflating your tyre to the right pressure. It’s in your owner’s manual or on the inside of your driver’s side door. After that, keep an eye on it for roughly a week. If the pressure remains constant, you’re probably safe!
If your tyres continue to lose air, there are three possible causes: valve stem failure, rim corrosion, and mounting issues.
Failure of the Valve Stem
A valve stem is a device that allows you to inflate a tyre. It can break, decay, or become damaged in extreme weather. This is because of exposure to the environment since it sticks out of the tyre. If this occurs, the inner tube seal of the tyre will break. As a result, air slowly and steadily leaks out of the tyre.
At the wheel rim, air can potentially escape. This is the point at which the tyre and wheel come together. When you hit a pothole, skim the curb, or simply drive over it, the rim might become damaged. As a result, the tyre and rim become misaligned. It is critical to have a tight seal between these two components. Upon damage, it causes the tyres to progressively leak.
Tyre Pressure Monitoring System Guide
All standardized automobiles manufactured post-2008 carry the tyre pressure monitoring system, abbreviated TPMS. When tyre pressure goes below normal, sensors detect it. As a result, the indicator light on your dashboard will illuminate. This warning light indicates that one or more tyres may require inflation. But your TPMS is more than meets the eye. Here’s all you need to know about this critical safety feature.
TPMS: More Than a Safety Device
This system, which monitors and alerts you to low tyre pressure, is a critical safety feature. Under-inflated tyres are risky since they can cause blowouts. Driving with under-inflated tyres increases braking distance significantly. Furthermore, tyres with insufficient air perform badly on the road due to a lack of traction and responsiveness.
However, TPMS is more than just a safety function. Tyres with low pressure may wreak havoc on your fuel efficiency and your wallet. Under-inflated tyres need your engine to use more energy to drive your vehicle ahead. Insufficient air in your tyres reduces your fuel economy by 3%.
Your tyres will also have increased and uneven tread wear. This is unfixable, even with a tyre rotation. A whole replacement tyre purchase is necessary.
Methods for Detecting TPMS Pressure
TPMS systems use one of two methods to detect tyre pressure in your vehicle.
The Direct Method
In the case of low tyre pressure, each wheel contains a pressure sensor that sends information to your dashboard. Unfortunately, this approach to direct detection is vulnerable to environmental conditions like weather. These variables can skew readings. Furthermore, the batteries that power these sensors might fail or stop operating over time.
The Indirect Method
Direct TPMS adds a pressure sensor to each tyre. Indirect pressure solutions use current ABS and ESC wheel speed sensors to calculate pressure. While in motion, these sensors detect minor variations in tyre sizes. Softer or under-inflated tyres have lower diameters than standard tyres. This causes the system to send a signal to your dashboard.
These are strategies used by many automobile manufacturers and models. Different automobile manufacturers and models employ one or both approaches to alert you when your tyres are low on air.
The Causes of TPMS Light Failure
Even after you check your tyre pressure and pump your tyres, the indicator on your dashboard may stay illuminated.
Recent Temperatures Dips
For every 10-degree reduction in temperature, tyre pressure lowers by around a pound. A severe cold snap immediately after a tyre fill might be the cause of your light remaining on. To guarantee consistent pressure, check your pressure once a month with a dependable gauge. You can obtain the most precise reading before starting your automobile and driving.
Slowly Leaking Tyre
If the tyre has a gradual leak, the signal light may remain illuminated. Assume you always fill your tyres with air but continue to see the light on your dashboard. This is a reminder to have your tyres examined for a nail or other puncture that is causing continuous slow leakage.
Recent Tyre Replacement
A tyre change may mistakenly harm the TPMS in the wheel rim. The next time you change your tyres, check the pressure light right away. This eliminates false readings.
Mechanical Component Failure
TPMS uses mechanical components. These components have the potential to fail. If, after filling the tyres, you still observe a pressure warning light. After ruling out a slow leak, the TPMS is most likely damaged.
Yet driving with a low-pressure light on is not recommended! If your TPMS system needs repair, have it repaired.
