The tyres play a critical role in your vehicles safety, with little more than a hand size amount of tread per tyre making contact with the road surface at any given time. This is critical for cornering, Steering, acceleration and braking, so your vehicles tyres must be in a good condition.
Good tyre tread becomes even more critical on wet roads
The tyre tread is designed to disperse water from the tyre's contact area, allowing the tyre to grip the road and perform as anticipated for the driver.
Without good tyre tread in wet conditions, the driver will have difficulty in accelerating and cornering.
More importantly, the Tyre tread is responsible for ultimately stopping your vehicle when braking; the brake system can be operating fine, but if you don't have good tread contact with the road, the car can just simply glide on the road surface when you need it to stop.
To ensure this, tyres have a minimum tread level indicator.
If the tread is worn down to these bars or the bars are visibly worn, the tyre is illegal and needs to be replaced.
Correct Tyre pressure
The recommended tyre pressure is shown on the tyre placard attached to the car body (usually on the driver's door pillar) and is also listed in the owner's manual.
Tyre pressures are given for everyday driving and also when loaded up with the maximum number of people (the car can legally carry) and luggage, so if you are going on a trip, the pressure will differ from city driving with an unloaded vehicle.
The tyre pressure is also critical to the vehicle's suspension performance, allowing it to ride and corner efficiently while the tyres maintain good contact with the road surface.
