Grip is vital – especially in winter. By law, all cars driven on public roads must have tyres with a xx tread pattern. Slicks are only allowed in motor racing – sorry.

The tread’s main job is to expel water that affects the tyre’s contact with the road. But that’s not the only reason you need decent tread: did you know that the braking distance for a worn tyre with a tread depth of 1.6mm is almost twice as long as that of a new tyre with 8mm? Not all tyres are created equal, and tread patterns are specifically designed for particular functions. So if you do a lot of off-roading in your 4x4, you get a special off-road tyre, and if you only ever ramp pavements, you’ll use another tyre altogether.

Even if they all look the same, you need to choose the right one. And don’t for a second think that aquaplaning only happens at high speed…

Note: In nearly all cases, a pair of replacement tyres should be fitted to the rear of a car, as this is where most of the weight is. Don’t be afraid to bring it up with whoever is changing them.

Aquaplaning: Slippery When Wet

What is it? Your vehicle’s wheels lose traction due to water on the road. What does it feel like? Sometimes it’s not immediately obvious, but the steering will become unresponsive and the car’s tail will start weaving.

What causes it? A combination of water depth, tyre pressure, the condition of tyres and speed. How can you prevent it? Gear down, stay in the tracks of the vehicle in front of you (maintain a safe following distance) and stick to the middle of the lane as water tends to gather on the edges.

What must I do if I aquaplane? Avoid braking or accelerating. Push in the clutch. Put on your hazards if you have time. Firmly grip the steering wheel and steer in the direction you want to go. Be aware of cars and other obstructions around you.
