A survey released today by the RACV and Victorian Automobile Chamber of Commerce found that 20 percent of cars in Victoria have at least one worn or unroadworthy tyre.
The study looked at 1,000 cars last month and found of those 200 had at least one tyre that had worn.
Chief engineer for the RACV, Michael Case said that driving on worn tyres could increase the distance it takes a car to brake and road safety. "Increasing the braking distance can increase the chance of running into the car in front of you and having an unnecessary collision and if that collision is serious enough certainly it can cause injuries" said Mr Case.
It is widely accepted that tyres are one of the most important parts of a vehicle. As tyres are the only part of a vehicle in contact with the road, they affect acceleration, braking and cornering.
As well as the safety issues associated with driving a vehicle with a worn tyre, drivers can be fined for "driving an unsafe vehicle" and fined AUD$171, in addition police may "defect" the vehicle, restricting its use until repaired. Victorian law requires that tyres have a minimum tread depth of 1.6mm.
Wikinews investigated the average price of each tyre on a typical large and small Australian sedan, and SUV and found the cost to be AUD$129, AUD$105, and AUD$191 respectively.
