Tyres are a key component of the safety of any vehicle and the condition of tyres is a vital factor in preventing road accidents. It is worth remembering that the only part of a vehicle touching the road are the tyres and acceleration, braking, steering and cornering all depend on them. Neglected tyres can lead to devastating consequences.
Tyres have four basic functions to perform:
1. Transferring traction and braking forces to the road surface:
2. Changing and maintaining direction of travel:
3. Supporting the load of the vehicle and its contents
4. Absorbing road shocks.
Some Tyre care tips
- Set a date – Mark a date on the calendar which is the day you check your tyre pressure once each month. All you need is a pressure gauge and if you don’t have one, most service stations do. You will find the correct pressure for your car in the owners handbook, or on the inside of the driver’s door frame. It is crucially important to do this for the life of the tyre life and for fuel economy as under inflation will increases the amount of fuel your car is using. As grip and braking performance will also be effected there is also a safety consideration.
- Take a closer look – Look for wear on your tyres as the tread directly affects how it grips the road, so it’s important to check your tyres regularly for uneven wear and foreign objects wedged in the tread. All of these types of damage can lead to a sudden blow out so stay away from potholes and kerbs in particular.
- Know when to say goodbye – If the tread wear limit is below 1.6mm or the tread wear indicator bars are showing you MUST replace the tyre.
- What to swap – The purpose of regularly rotating tyres is to achieve more even wear on each tyre. Check the car’s handbook first for specific advice about your car but if threre is no information in the manual, then the tyres should be rotated every 12,000 km and its good practice to fit the newest tyres on the rear. (Generally if you have a front wheel drive car, your front tyres will wear more quickly than your rear tyres and vice versa for rear wheel drive vehicles).
- What to buy – You should buy tyres that are recommended by your car’s manufacturer for the particular model you drive as this is likely to be the tyre best suited to your car.
