Your tyres are arguably the most important part of your vehicle. Why? Because they are your only contact with the ground. This is where rubber meets the road, and at any one time, the each tyre touches that road on an area roughly the size of a postcard. That really isn’t much, and this is why you need to make sure your tyres are up to scratch. It’s not only your safety that’s at stake, but that of your family, pedestrians and other road users.
Four main functions of tyres.
Supporting your car
The average family car weighs close to two thousand kilograms, and all that weight needs to be supported by something. Each tyre needs to be inflated enough to support the weight of the car, passengers and cargo.
Absorbing the bumps
It’s not just your shock absorbers that stop you having a bumpy ride. The air/nitrogen in your tyres take most of the impact and act as a cushion for your car.
Obviously the most important aspect of driving when it comes to safety. Bald tyres aren’t going to help you in an emergency braking situation.
Tyres are extremely important when it comes to steering. The tyre type, quality and size all play a part in the vehicle’s steering capability.
Checklist for tyres
The deeper the tread depth the better, and new tyres should have a depth of around 5-7 millimetres. In New Zealand, the minimum tread depth required by law is 1.5mm, however, in wet conditions, anything under 3mm isn’t really recommended.
Under inflated tyres will reduce steering capacity, increase your stopping distance, use more fuel per tank, and overall reduce your car’s performance. Over inflated tyres run the risk of a blowout, and that’s the last thing you want travelling at 100khp. Even if they don’t explode because of the increased pressure, the contact with the road will be smaller, resulting in even more problems.
