When To Change Tyre

When To Change Your Tyre

A Michelin Man figure on the shoulder of Michelin tyres shows the location of the tread wear indicators situated in each of the main grooves of the tread.

These indicators are small raised areas at the bottom of the grooves of the tread pattern.


If the surface of the rubber is at the level of these raised areas, the tyre is most likely very close to the safe limit of 1.6 mm, or could even be below it! Use of worn-out tyres increase the probability of tyre failure, and in wet conditions can cause the tyre to lose traction suddenly. In most countries, it is illegal to drive with less than 1.6mm of remaining tread depth.
Taking care of your tyres with the Michelin Safety and Safety tips will not only guarantee your safety but also save your tyre life.

Safety And Safety Tips - Michelin

Make sure you not only select the right tyres, but also regularly maintain them to ensure they perform at their best.   

A BIG JOB FOR A SMALL SURFACE

The part of your tyre that is actually in contact with the road is only about the size of a man’s hand. Your safety, comfort and fuel economy depends on that very small surface. It’s important because your tyres:
  • Are the only link between your vehicle and the road
  • Carry the entire weight of your car, a load of up to 50 times their own weight
  • Respond to driving inputs such as steering, acceleration and braking from the car to the road surface
  • Absorb every obstacle on the road

Change your tyres before your tread depth is worn to 1.6mm. To make life easier, MICHELIN tyres are equipped with tread wear indicators situated in the base of the main tread grooves at the height of approximately 1.6mm.
A QUICK AND EASY SAFETY MEASURE
Make sure to regularly check the tread depth of your tyres and replace them when they are worn. This will guarantee maximum traction and grip, helping you avoid any unpleasant surprises. Your safety depends on a good level of tread depth because:
  • The tread grooves disperse water from underneath your tyre, helping maintain control
  • The more tread depth you have remaining on your tyres, the more water you can 
    disperse and therefore reduce the risk of aquaplaning
  • Correct air pressure as well as regular vehicle maintenance will ensure your tyres
    perform at their best for the longest possible time
  • The tread grips to the road, affecting the distance you require for braking

MICHELIN Recommends

Check the pressure of your tyres, including your spare, monthly and before any long journey, preferably when your tyres are cold. If they are hot, it is advisable to add 4-5 psi (0.3 bar) to the pressure recommended by the vehicle manufacturer.

CHECK YOUR TYRE PRESSURE EVERY MONTH



Correct tyre pressure reduces the risk of losing control of your vehicle. It also protects your tyres from premature wear and irreversible damage to the internal construction. Tyre pressure can drop due to small perforations, the natural escape of air through the tyre's components or even from a decrease in ambient temperatures. So it is important to check it once a month, because:
  • Low pressure increases the risk of damage to your tyres
  • Excess pressure of 20% can reduce the life of your tyre by up to 10,000 kms
  • Correct tyre pressure will even save fuel

The recommended tyre pressure can be found:
  • In the User's Manual of your vehicle
  • On the labels on the side door beside the driver's seat
  • In the storage drawer near the driver's seat
  • On the inside of the fuel flap
But NOT on the tyre. The inflation pressure shown on the tyre sidewall is only the maximum tyre inflation pressure.

Have your wheels balanced when a tyre is replaced, a balance weight is moved or removed or you purchase new tyres.
KEEP YOUR BALANCE FOR LONGER LIFE

Balancing helps prevent premature wear of your tyres and eliminates vibration. It also protects the suspension, steering system and bearings of your vehicle. A wheel is out of balance when one area is heavier or lighter than the rest. This will cause:
  • Uneven and rapid tread wear
  • Vibration
  • More stress on front-end parts
  • Front-end parts to wear prematurely

MICHELIN Recommends

If your tyre has come into contact with a solid object such as a curb or pothole or you have noticed uneven wear on your tyres please go to a Michelin store to have it thoroughly inspected.
ENSURE SAFETY WITH CORRECTLY ALIGNED WHEELS AND AXLES

 It is difficult to tell if your wheels and axles are correctly aligned while driving. But if your vehicle’s suspension geometry is incorrect, its road handling may be disrupted and your safety compromised. It’s important to ensure correct alignment to:
  • Get the best road handling
  • Protect your tyres from irregular and / or rapid wear
  • Save fuel

MICHELIN Recommends

For optimum efficiency, regularly check the pressure and condition of your tyres, especially during tyre rotation as many vehicles specify different pressure on the front and rear axle.
FOR COMPLETE CONTROL, FIT YOUR NEW TYRES TO THE REAR AXLE

Rear wheels are not connected to your steering wheel, which makes it extremely difficult to judge their grip while driving. So for your safety, always fit new, or the least worn, tyres to the rear wheel positions to ensure:
  • Better control in emergency braking or tight corners
  • Less risk of losing control of your vehicle, especially on wet surfaces
  • Better road holding, particularly in difficult situations, whether your car is front or rear wheel drive


MICHELIN Recommends

Replace your valve every time you change your tyre. It’s an inexpensive way to protect your tyres, vehicle and yourself.
VALVE CAPS PROTECT YOU AND YOUR TYRES

Valves and their components are ordinarily made of rubber, so they are subject to deterioration over time. Replace them when you buy new tyres. At high speeds, a cracked, deteriorated rubber valve stem can bend from centrifugal force and allow air loss. The valve cap is also important. It is the primary air seal and helps to keep out dust and dirt particles. You should check that your valves and valve caps are in good condition to:

For a reliable diagnosis and guarantee of safety, call on the services of a professional.
THE FIRST STEP TO REPAIR A TYRE IS TO CALL A PROFESSIONAL

When a tyre needs to be repaired, it is essential to have an authorized tyre retailer or technician remove the tyre from the wheel and inspect it from the inside. It is absolutely necessary because internal damage is not visible while the tyre is mounted to the wheel. A professional will: 
  • Verify the internal condition of the tyre, detecting any damage not visible on the surface
  • Ensure the correct methods and materials are used to repair the tyre
  • Ensure the tyre is refitted correctly, optimizing handling and comfort

  1. Excellent post and a great run down - I think most people take for-granted that tyres need changing and that you should not only have Summer tyres but stock up on Winter tyres too!

  2. i used the universal tyres, and it is the best way.

  3. Very interesting blog. A lot of blogs I see these days don't really provide anything that attract others, but I'm most definitely interested in this one. Just thought that I would post and let you know.
