TYRE TECH 1

What is Tyre Pressure?

Tyre pressure refers to the amount of air inside a vehicle's tyres, measured in pounds per square inch (PSI) or bar. Proper tyre pressure is crucial for safety, fuel efficiency, tyre lifespan, and overall driving performance.

​

Maintaining the correct tyre pressure ensures safer driving, better fuel economy, and longer-lasting tyres. Regularly checking and adjusting tyre pressure prevents unnecessary wear and enhances vehicle performance. Always make it a habit to check tyre pressure monthly and before any long trips.

​

How to Check Tyre Pressure

Checking tyre pressure is a simple process that requires a tyre pressure gauge or can be done at a fuel station with an air pump. Follow these steps:

1. Find the Recommended Pressure

   • The correct tyre pressure for your vehicle is typically found in the owner's manual or on a sticker inside the driver's door or fuel cap.

2. Use a Tyre Pressure Gauge

   • Remove the valve cap from the tyre.

   • Press the gauge firmly onto the valve stem to get a reading.

   • Compare the reading with the recommended PSI.

3. Check When Tyres Are Cold

   • Tyre pressure should be checked when the tyres are cold (before driving or at least 3 hours after driving) for accurate readings.

 

How Often Should You Check Tyre Pressure?

• Ideally, check tyre pressure at least once a month and before long trips.

• Check more frequently if you often drive on rough roads, carry heavy loads, or experience extreme temperature changes.

How to Add Air to a Tyre at a Fuel Station

Most fuel stations have air pumps. Here's how to add air properly:

1. Locate the Air Pump

   • Park near the air pump and ensure you can reach all four tyres.

2. Set the Correct PSI

   • Some air pumps allow you to set the desired PSI, while others require manual checking.

3. Remove the Valve Cap

   • Unscrew the cap and keep it in a safe place.

4. Attach the Air Hose

   • Press the hose nozzle onto the valve stem and hold it firmly.

5. Inflate to the Recommended PSI

   • If the pump has a built-in gauge, it will show the pressure.

   • If adding air manually, check with a separate pressure gauge.

6. Replace the Valve Cap

   • Once done, screw the cap back on to prevent dust or dirt from entering the valve.

What Happens if Tyre Pressure is Unequal?

Having different pressure levels in the four tyres can lead to several issues, including:

1. Uneven Tyre Wear – Overinflated or underinflated tyres wear out unevenly, reducing their lifespan.

2. Poor Handling & Stability – Unequal pressure affects steering control, especially during cornering or emergency maneuvers.

3. Increased Fuel Consumption – Incorrect pressure increases rolling resistance, making the engine work harder and use more fuel.

4. Braking Issues – Uneven tyre pressure can reduce braking efficiency, making stopping distances longer.

5. Increased Risk of Blowouts – Underinflated tyres overheat more easily, increasing the risk of a blowout.
