The air pressure in your tyres supports the entire weight of your car. Sounds crazy, but you know what’s crazier? Not regularly checking your tyre pressure. Maintaining correct tyre pressure helps to keep you (and other road users) safe, improves vehicle performance, decreases fuel costs and ensures that you are getting the most life out of your tyres.
Over Inflation

Over inflated tyres gives you a bumpier ride. When a tyre is over inflated, the outer tread pattern rounds out, which causes the centre of the tyre to wear out much faster than the outer edges.

Overinflated tyres:
  • Have a smaller contact area with the road. 
  • May effect breaking 
  • Create uneven tread wear - the centre of the tyre wears out faster 
  • Compromise handling 
  • Creates an unpleasant ride - the tyre is unable to ‘soak up’ the bumps 

Under Inflation

Under inflated tyres are one of the leading causes of tyre failure. Low pressure means that too much of the tyre touches the road, increasing friction and greatly reducing the life of your tyres. A tyre doesn’t need to look a little flat to be under inflated, so always refer to your owner’s manual for the required tyre pressure level for your car and get testing!

Underinflated tyres:
  • Can increase rolling resistance 
  • Increase fuel consumption - due to the rolling resistance, which makes the engine work harder 
  • Creates uneven tread wear - the edges of the tyre wear out faster 
  • Affect braking performance 

Effects of under and over inflation of tyres

When checking your tyre inflation it can also be a good time to check tread depth and look for any damage or irregular wear  to your tyres. Consider this a friendly public service announcement from all of us here at Tyre Review!
