Regular monthly inspection of your tyres will increase the chance of spotting any alignment or mechanical wear early, so small problems can be resolved before they become costly.
Correct air pressure
Always keep your tyres inflated to the vehicle manufacturer’s specifications which you will find in your owner’s handbook. Don’t forget to inflate and check the spare.
If you are inflating a tyre more often than usual then it might well have a slow puncture. This could be caused by a nail or a sharp stone lodged in the tyre or a leaking valve. Have it checked by a tyre dealer.
Have your tyres rotated at least every 8,000km in the correct pattern for your vehicle.
