Help! What is the best tyre pressure for my car?

Under-inflated tyres negatively affect handling, safety and the overall performance of your car - make sure your tyre pressures are correct.
 

How do I find out the correct tyre pressure for my car?

Tyre pressures vary dependant on size. To test your tyre pressure, take off the dust cap on the tyre’s valve. Fix on the pressure gauge and make a note of the reading. Your driver’s handbook will provide you with the correct pressure ratings for your tyres. It is always best to check as the tyre pressure for the front and rear may differ. If your tyre needs extra air, you should inflate it using an air pump at home, or use the facilities provided in many petrol stations.
 

What can affect tyre pressure?

Tyre pressure can be affected by weight/load, speed and even by the way you drive. You can find the optimum tyre pressure for your tyres from your driver's handbook. You will be presented with two sets of readings - a standard reading and a reading for when you are carrying additional weight such as passengers or luggage.

Extra load will reduce tyre pressure dramatically so it is important your tyre pressures are adjusted to compensate for additional weight, especially if you are preparing for a long journey.
 

Checking tyre pressure - how and when to do it

In order to get the most accurate tyre pressure results you need to check them when they are cold i.e not just after your vehicle has been driven. 
At Protyre, we recommend you check your tyre pressure at least once a month.

My tyres are a bit flat - is that OK?

Although you will still be able to drive your vehicle without noticing a huge difference to performance, long term, under-inflated tyres are dangerous for a number of reasons:
  • Tyres can overheat resulting in increased chance of tyre bursting
  • More likely to be affected by general wear and tear
  • Steering impacted
  • More fuel consumption
 

Over-inflated tyres

Under-inflated tyres carry their own risk as outlined above but over-inflating your tyres is not the solution. Over-inflation reduces the surface area of tyre in contact with the road. Less surface area means less grip which can be extremely dangerous in bad weather.

Too much air will also increase the likelyhood of damage upon impact and quicken tyre wear.


Tyre damage

Checking your tyres regularly will help minimise the risk of damage but if you notice any abnormalities they must be checked thoroughly by a tyre professional. You may notice a reduction in performance as your tyres wear but how do you know when you should actually replace a tyre? Click here to find out.
