How to check tire life

The only point of contact between your car and the road is the tires. As a result, they must be in tip-top shape in order to provide a smooth and dependable ride. Tires wear out as you drive them, and depending on how you drive, the road conditions, and how much you brake, they can wear out faster. As a result, it is critical to understand tire life and health.

Let’s get started with the methods for checking tire life listed below.

Know the tread depth of your tyre

Tread depth decreases as tires wear out. As a result, the car has less grip, resulting in less stability and traction. Measuring a tire’s tread depth is a common practice for determining the life and health of a tire. A car tire’s tread depth is measured in 32nds of an inch.

Tread depth on new tires is typically 10/32 or 11/32 inches. As a result, measuring the car’s tread depth can be a relatively simple task. Here’s what tread depth says about tire condition and what you should do about it.

8mmThe tire is in new conditionKeep driving
5mmPartially worn outNeeds replacement soon
2-3mmCompletely worn outNeeds immediate replacement


The most common way to check tire life is with a coin. Here’s how to use a 5-rupee coin to measure the depth of a tread.


Step 1: Insert a 5-rupee coin into the tire’s groove between the ribs. Ribs are the raised pattern on the tires of your car.

Step 2: Position the coin so that the crescent’s base is facing the tire’s surface. The following scenarios may represent the health of your tire. Access and learn about the condition by looking at the examples below.

Case 1: If the year on the coin is dipped in the groove and the moon’s base is at par or raised from the tire’s surface, your tire is new. If this is the case, your tire is brand new, and you should not be concerned about its condition.

Case 2: If the year on the coin is partially dipped in the grooves of your tire, your tire is partially worn out. Your tire’s remaining tread is estimated to be around 5mm, and it will need to be replaced soon.

Case 3: Your tires’ tread is approximately 3mm if the year is clearly visible and the grain design on the coin’s boundary is partially visible. You must replace the tire as soon as possible.

Unusual tread wears and their causes

The tread on your tires may reveal important issues with your vehicle. The tread depth may be irregular at times, and you may notice cracks on the tire walls. Such incidents reveal critical issues with your vehicle that you may have overlooked. The following are some of the conditions that your car’s tire tread reveals.

1. Treadwear on both sides 

If the tread on both tire edges is worn out, your tire pressure is consistently low. As a result of the weight, the tire is compressed down to the point where both shoulders of the car tire make contact with the road. As a result, the treads on both sides are wearing out.

This type of wear reduces fuel economy, increases resistance, heats the tire, and reduces tire thickness.

2. Treadwear in the centre

Excessive wear in the center of the tire indicates that the tire is overinflated due to high pressure. Reduce your car’s tire pressure and keep it there to extend tire life. On the sideways door, check the recommended pressure by your car manufacturer.

As a result, the center of the tire wears abnormally while the edges remain in good condition.

3. Uneven Tread wearing

If the tires are unevenly worn, there could be an issue with the car’s alignment. Uneven alignment causes tires to experience more friction and wear out from a variety of angles.

Get your car’s alignment checked out by a tire expert or an authorized dealer.

4. Cracked/ damaged sidewalls

Cars may collide with sidewalks or speed bumps, causing the tire sidewalls to deteriorate. And, over time, you may notice cracks or damage. This is concerning because the tire has the potential to explode upon impact. A puncture cannot be repaired, so the only option is to replace the tire.
