How to check if your tyres are roadworthy

Driving on tyres that aren’t roadworthy can be dangerous – for you and other road users. Check whether your tyres meet the legal safety requirements and learn how to keep them in good condition. That way you can avoid having to replace them earlier than you need to.

How to check if your tyres are roadworthy

Make sure you have the correct tread depth

The tread on your tyres must be a minimum of about 1.5 millimetres. Any shallower and they’re considered too bald to safely drive on. You can check with a tread depth gauge, which you can buy from a tyre retailer or auto store.

To measure the tread depth, insert the gauge into the tread at different points around the tyre. If it shows that the impression is below 3mm, it’s time to consider new tyres. Brand new tyres will have a tread depth of 8mm.

Air pressure

Driving on tyres that are under or over inflated can be dangerous. To check the air pressure, you'll need a tyre pressure gauge. You can buy one from a tyre retailer or auto store. Most petrol stations also have air pumps that you can use to inflate your tyres.

The recommended air pressure for your tyres is usually listed in your car's manual or on a sticker inside the driver's door. If the pressure in your tyres is below the recommended level, pump them up. If it’s above, let some air out.

Wheel alignment

Driving on wheels that are not aligned can cause premature wear on your tyres and may also affect your car's handling. To check your wheel alignment, you'll need to take your car to a mechanic or tyre retailer. They will use specialist equipment to check the alignment of your tyres and adjust it if necessary.

Checking the condition of your spare tyre

You should also check the condition of your spare tyre, in case you need to use it. Take it out and check its tread depth and air pressure; if it’s bald or has low air pressure, you'll need to replace it before using it.

How to maintain healthy tyres

Drive safely

One of the best things you can do for your tyres is to drive safely, which means following the speed limit, braking gently, and not accelerating too sharply.

Pay attention to sharp objects

Watch out for sharp objects on the road, as they can puncture your tyres. If you hit a pothole or something similar, check your tyre as soon as possible.

Rotate your tyres regularly

Switching the position of your tyres means they have a chance to wear out evenly.

How often you need to rotate your tyres depends on your car's make and model, so it's best to check your manual. Ask your mechanic if they can rotate them when doing a general service, or head to a tyre retailer.

Check your tyres regularly

Look for any signs of wear and tear. Check the tread depth, air pressure, and wheel alignment. If you notice any problems with your tyres, get them fixed as soon as possible.

Stay safe on the road and off

Following these tips can help ensure that your tyres are roadworthy and safe to use. Remember, it's always best to take your car to a mechanic or tyre retailer for a professional opinion if you're ever in doubt.
