Tyres will deflate at approximately 1 PSI (pound per square inch) in a month. Bad roads and high ambient temperatures also increase the rate of deflation. So, ensure that you get the tyre pressure checked frequently. Maintaining the correct air pressure in the tyres also ensures better mileage, so it’s a win-win!
The depth of the tread should always be more than 1/16th of an inch or 1.6 mm. If the vehicle is driven on slick or wet surfaces regularly, it is recommended that the depth should be at least two times the above. Newer tyres have ‘tread wear bars’—little rubber bars that run perpendicular to the grooves. As the tread wears off to the same level as the rubber bar, it provides a clear indication that the tyres need to be replaced. So, pay attention and ensure that your tyres are in a top shape.
In case the car is being driven on low air pressure, the sidewalls of the tyres expand and eventually become weak. As the tyre’s outer surface begins to weaken, bulges or cracks begin to develop. This can lead to tyre blowouts. Check the sidewalls of the tyres for these tell-tale signs that the car needs new tyres.
During the course of driving, if you feel any additional noise or vibrations filtering into the cabin, there may be something wrong with your tyres. Most likely, the vibrations are generated when the tyres are not correctly balanced. This will lead to faster tyre wear and may damage the suspension of the car. So get the tyres balanced every 10,000 km or as recommended by the manufacturer.
Tyres tend to show signs of aging such as surface damage after five years. This includes the time they are sitting at the tyre shop. So, always check the date of manufacture when purchasing tyres. The manufacturing date is usually a four-digit number mentioned on the sidewall of the tyre. The first two digits are the week of manufacture while the second two digits are the year of manufacture.
