Tyre Tread Depth Checker

Changing tyres 


One of the routinely overlooked safety factors in a vehicle is the quality of the treads on the tyres.

There are two automotive parts that undergo wear on normal usage and need replacement when its life is over, one is the brake pad or brake lining and the other is the tyre. Both are critical for safety of the passengers.

Typical tyres are rated for a life of 2 to 3 years under normal or average driving habits. If you are a road warrior, then tyres need to be changed more often; and if you rarely use your vehicle, then the tyres will last several years. Driving habits also influence the life of the tyres. If you are a safe driver with a limited number of quick stops from high speeds, the tyres will last longer. On the other extreme, if you enjoy the high speed, quick stop, adrenaline rushing driving style, then the tyres are likely to need change more often.

How to determine when to change your tyre? 

Typically, this is done by measuring the “tread depth” of the treads on your tyres. ”Treads” are the grooves on the tyre surface and help in providing “grip” to the road. 

During rains or if you are driving on wet surfaces, the grooves (or treads) also help in removing the water so that the rubber can establish contact with the road and provide the “grip” needed for safe driving. The speed of the vehicle also influences the "grip", with higher speeds providing less "grip".

What does my measured data mean? 

A Brand new tyre will have a tread depth of about 8 mm.

As the vehicle is driven, the tread depth keeps reducing because of wear of the rubber in the tyre surface. 

  • Recommended tread depth for summer driving is 3 mm.
  • Recommended tread depth for winter driving is 4 mm.
  • The recommended time to absolutely replace the tyres is when the tread depth is less than 1.5 mm.

When the “tread depth” is less than 1.5 mm, the thickness of the tyre needed to keep the air pressure sufficient inside the tyre is compromised.

You could end up with small “leaks” or pressure drops much quickly on tyres with insufficient treads.

The lower “tread depth” also limits the ability of the tyre to “pump” out the water from the road to provide “grip” needed for safe driving.

Air pressure used in the tyres also play a significant part in ensuring even wear of the tyre treads. Underinflated or overinflated tyres tend to wear non-uniformly, so it is also important that you check the tread depth at multiple locations on the tyre - across the width of the tyre.

The above numbers are valid for typical passenger cars. The recommendations may be different for trucks, buses, 2 wheelers or other off-road vehicles. You should check your vehicle manual for details.

FAQ:

1. Is this a portable Unit?

Certainly. The unit is compact, runs on a single battery and can be taken anywhere you go.

2. Do the batteries come with the unit?

No, the battery needs to be purchased separately. There are transport regulations for shipping batteries and for products that include batteries, as certain batteries could potentially cause fire or explode when exposed to heat.

3. How do I ensure the reading to be accurate?

You need to install the device on a flat surface and calibrate to "zero". This can be done by clicking the calibration button when pressed against a flat surface. Once this is done, you are good to go and can use the device to measure the tread depth of your tyres.
