How to maximise the life of your tyres and stay safer on the road.

Bridgestone takes pride in offering professional services and advice to assist you with choosing the right tyres for your vehicle.

It is very important for you to know how to maintain the tyres you purchase to ensure the effectiveness and safety of those tyres.

Ensure your tyres have more than 1.6mm of tread

Most new tyres start out with about 8-9mm of tread. When the tread wears, the tyre’s ability to disperse water reduces. Regularly check the indicators on your tyre’s tread pattern, which will show as lines across the tread when it’s reduced to 1.6mm.

Check your tyres weekly, either yourself or use a tyre specialist.

Check your tyre pressure using an accurate tyre gauge and when your tyres are cold. For heavy loads or sustained high-speed operations, increase the inflation pressures according to your vehicle’s recommendations.

Rotate your tyres regularly.

For maximum tyre life, you should rotate your tyres every 5,000 – 8,000 km, or according to the vehicle manufacturer’s recommendations. Tyres can wear differently depending on their position on the vehicle due to vehicle loading or suspension and steering set up. Rotating your tyres will give a more even, safer wear pattern and prolong tyre life.

Ensure your tyres are correctly inflated.

Under or over-inflation is dangerous and can lead to excessive tread wear. Look for the manufacturer’s recommended tyre pressure, listed on the sticker usually located on the driver’s side door pillar or fuel flap, or have a tyre specialist inflate it for you.

Check the age of your tyres.

There is no set rule for at what the age tyres should be replaced. However, some car makers advise against using tyres over six years old. Over time heat, sunlight and ozone can affect the tyre compound. To check the age of your tyres, look at the Tyre Identification Number (TIN). The last four digits indicate the week and year the tyre was made, for example a tyre with TIN XXX4804 was manufactured in the 48th week of 2004. If in doubt, check with a tyre specialist at your nearest Bridgestone Select.

Get a professional wheel alignment regularly.

Have a professional wheel alignment every six months or 10,000 km, whichever comes first. Misaligned wheels will cause your tyres to wear excessively and irregularly. Having correctly aligned wheels is also essential for safe handling and braking; it can even help to reduce driver fatigue.

The tread on your tyres is what maintains your driving control, grips the road, disperses water and keeps you safe.

A worn tyre increases the time it takes you to brake in the wet, as well as your chance of losing control.

Understanding tyre size
Made easy with these tips from the experts.

1. Width
205 indicates the section width of a tyre in millimetres.

2. Aspect ratio
60 is a tyre’s aspect ratio which is its height from the base of the tread to the rim. This number represents a percentage of the tread width. For example, the height of this tyre is 60% of its width. Low profile tyres have smaller aspect ratio percentages.

3. Tyre construction
R means that the tyre has radial ply construction, meaning the way in which it has been constructed. Most passenger tyres are constructed this way so you will rarely find a car tyre without an R.

4. Rim
15 indicates the diameter of the wheel rim. So if you are buying wheels for existing tyres, this is the size in inches you will require.

5. Load index
91 is a code which indicates the maximum load capacity of the tyre. See load index table for passenger car tyre load index ratings.

6. Speed symbol
V is a code which indicates the speed at which a tyre can be safely operated, subject to the tyre being in sound condition, correctly fitted and with the recommended inflation pressure. See speed symbol table for passenger tyre speed symbol ratings.
