Just like any product which has a shelf life, tyres are also items that become too old and worn out after much use. Driving cars with worn-out tyres is a recipe for disaster, as they can result in cars spiralling out of control.

With worn-out tyres, there is the chance that you will get stranded in the middle of nowhere. So, it is vital to frequently check the state of your car tyres, particularly in winter. It is always good to know when your car tyres need to be changed.

Thankfully, this is no rocket science. Your tyres will display some tell-tale signs; you only need to spot them. Here are the top six signs for changing tyres one should look out for:

1. Tread Depth

What is the sign of a worn-out tyre? Mostly, you are required to change the tyres when they have around 2/ 32” of remaining tread depth. The latter is the distance between the top of the tread and the base of the groove. You may even change the tyres before such signs in case your car has been used much in inclement weather. But maintaining the professionally advised tread depth on your tyre is vital since the loss of tread depth reduces grip and traction on the roads and later on, compromises safety while driving. You can measure tread depth by viewing tread wear bars which are mostly invisible but can be spotted when the tyre has been worn down beyond the recommended tread depth. You can also use a tool called a tread depth gauge.

2. Rubber Cracks

The overall wear of your tyres is much affected by the weather. Inclement conditions such as particles on the road, acid rain, UV rays, and extreme weather cause inevitable cracks. Tyres do have anti-ageing chemicals, but such protection will not last forever.

Your mechanic will search for ozone cracks which are surface cracks only visible on the sidewalls and the base of the tread grooves. They become a serious problem when they descend into the rubber. Cracks on the sidewall occur when over time, chemicals and oils in the rubber gradually wear out when exposed to inclement weather. Also, the rubber starts to use its tightness and cracks start to appear.

3. Slits and Blisters

The top signs of worn-out tyres are the appearance of blisters, bulges, holes and slits on the tyre surface. Slits and fissures are dangerous since they permit the air in the tyre to escape, causing it to deflate naturally. Even though such slits are not much visible, in case your suspect them, it is good to take the car for a professional check-up.

4. Vibration

You may have noticed some vibration while driving the car. You must never ignore such vibration whether you are driving fast or slowly. It is mostly a balancing or alignment issue. Excessive vibration is not only tiresome but may impair driver judgment and result in accidents. When vibration is ignored for a long time, tyres are subject to excessive and uneven wear, ending in premature removal.

5. Weird Noises

Weird noises emanating from tyres are a cry for help. The worn-out tyres that are getting squeaky, thumping, or whining are demanding change. Noises indicate that tyres are not aligned properly or that the tread is damaged.

6. Old Age

Typically, after use of 5 years, tyres tend to display signs of surface damage and serious wear. In this period, the chemical structure of the tyre begins to deteriorate, which impacts tyre performance. It is always good to check the manufacturing date on the tyre.

In sum, checking for such tell-tale signs, at least fortnightly could save you from future trouble and extensive expenditure on the repair. If you are not sure if the tyres needed replacement, you could always contact a car service in Bangalore for expert guidance.
