What happens if tyre pressure is too high?
Consequences of overinflated tyres
Having tyres run over the recommended pressure creates various issues that can compromise safety and decrease the lifespan of the tyres.
What occurs
- Centre wear - The tread's centre bulges out and wears faster than its sides, reaching a result that is counterproductive to the lifespan of the tyre
- Reduced contact patch - There is less rubber in contact with the road, which reduces braking and cornering grip
- Harsher ride - The tyre becomes stiffer and less able to absorb road imperfections
- Increased vulnerability - Overinflated tyres more easily sustain damage from potholes and road debris
- Less stable cornering - In corners, the car can feel less planted and skittish
What Should My Tyres Be Pressurised To?
Always use the vehicle manufacturer's recommended pressure, found on the door frame sticker or in the handbook. Do not inflate to the maximum pressure printed on the tyre sidewall as this is the maximum capacity of the tyre, not the recommended operating pressure of the vehicle.
