Tyre Pressure
The Key to Optimal Performance, Safety, and Fuel Efficiency
-
Your tyres are the only point of contact between your vehicle and the road, so ensuring they have the right amount of air in them is crucial. Improper tyre pressure can compromise handling, shorten tyre life, and even impact your fuel efficiency. They can significantly affect the safety of your vehicle. Here’s what you need to know:
Why Pressure Matters
Safety: Underinflated tyres flex excessively, generating heat and increasing the risk of a blowout. Overinflated tyres have a reduced contact patch, which reduces grip and affects braking performance.
Handling and Comfort: Correct pressure helps maintain your vehicle’s designed handling and ride characteristics. Improper pressure can lead to unpredictable steering response and a harsher ride.
Tyre Wear:Â Tyres with incorrect pressure wear unevenly or prematurely, needing replacement sooner.
Fuel Economy: Underinflated tyres create more rolling resistance, forcing your engine to work harder and use more fuel. Pressure is a significant factor in fuel efficiency.
Where to Find the Right Tyre Pressure
Driver’s Door Jamb: Most vehicle manufacturers place a sticker on the driver’s door jamb (or sometimes on the passenger door) listing the recommended pressures for the front and rear tyres.
Owner’s Manual: Your car’s owner’s manual provides specific pressure recommendations and may offer guidance on adjusting pressure according to load.
Fuel Filler Door: Sometimes, pressure information can be found on the inside of your fuel filler door.
The Vehicle’s digital display shows the pressure, ensuring that all four tyres are correctly inflated for optimal performance and safety.
Checking Your Pressure
Monthly Checks: Make it a habit to check your pressure at least once a month.
Cold Tyres:Â Check your pressure when the tyres are “cold,” meaning they haven’t been driven on for a few hours or only driven short distances.
Pressure Gauge: Don’t just eyeball your tyres; use a reliable pressure gauge for accurate readings.
Important Notes
Different Load Pressures: Your owner’s manual may recommend higher pressures if you frequently carry heavy loads or tow a trailer.
Spare Tyre:Â Don’t forget to check the spare tyre’s pressure regularly too!
Pro Tip: A Tyre Pressure Monitoring System (TPMS). Many newer vehicles come equipped with a TPMS, which alerts you to low tire pressures. However, don’t rely solely on the TPMS – regularly check with a gauge for the most accurate readings.
Get the Most Out of Your Tyres Proper pressure ensures your tyres perform at their best, saving you money on fuel and replacement tyres while optimising road safety.
Important Notes: When evaluating various load pressures for tyres, it is essential to refer to the vehicle’s owner’s manual, as it may prescribe elevated inflation pressures for heavier loads to guarantee optimal performance and safety. However, it is imperative not to exceed the maximum pressure indicated on the tire’s sidewall.
