This is the width in mm of the tyre from sidewall to sidewall when it's unstressed and you're looking at it head on. This is known as the section width.
This is the ratio of the height of the tyre sidewall, expressed as a percentage of the width. It is known as the aspect ratio. In this case, 60% of 215mm, which would equate to the section height.
The rim diameter is the size of the rim your tyre is fixed to, this is always measured in inches. In this case the rim diameter is 16 inches.
The load index on a tyre is a numerical code associated with the maximum load the tyre can carry. Each code represents a value in kilograms per tyre, so if your vehicle was to weigh 2000kg, your tyre load index would have to be 500kg per tyre, which would give you a load index of 84.
All tyres are rated with a speed letter. This indicates the maximum speed that the tyre can sustain. Each letter represents a maximum speed capability.
Your Legal Obligations
It’s easy to take your tyres for granted. After all, tyre manufacturers continually develop and improve design to offer a better performance, but responsibility for their enduring safety rests with you – and it’s your legal obligation.
Tyres must be well maintained which includes tyre pressures inflated to the vehicle manufacturer’s specification.
The tyre must be identical across an axle.
Different types must not be fitted to the same axle (i.e. radial-ply tyres and cross-ply tyres).
Tyres must be free from lumps, bulges and tears, nor must any portion of the ply or cord be exposed. Cuts should be no longer than 25mm or 10% of the tyre’s section width – whichever is greater.
Winter Driving Tips
Our weather can be very unpredictable, and if the past few years are anything to go by winters are getting worse. Get prepeared for winter driving today. Carry extra clothing, blankets, tow rope, mobile phone and torch in case of breakdown.
Check your Car:
Clean lights, top up your screen wash and check anti-freeze levels.
Check your Tyres:
The greater the tread depth, the safer. Correct pressures are also vital for grip. At least 4mm of tread is recommended as minimum in winter.
Remove ice/snow and wait for windows to clear before setting off.
Take your Time:
Going too fast in poor weather or road conditions is one of the main causes of fatal accidents.
Stopping distances are doubled on wet roads and up to 10 times longer in snow or ice.
Avoid Flood Water:
If can't, check its depth, drive slowly in first or second gear keeping the revs high to prevent stalling. Check your brakes afterwards before resuming speed and use gentle short braking actions to help dry them. Skids can occur when the tyre tread is poor or the tyre is moving too fast to flush water from the road beneath it, rising up on the film of water without being able to grip. Ease off power.
