How to Maximise Tyre Longevity

This article provides practical tips for extending your tyres' lifespan on New Zealand's roads. Follow these guidelines to ensure your tyres perform safely and effectively for as long as possible.

The lifespan of your tyres, often referred to as tyre life, is influenced by several factors.

Road conditions

The country's road network is a mix of smooth urban asphalt, abrasive chipseal on highways, and winding gravel roads in rural areas. Driving on these varied surfaces, along with common hazards like potholes, can wear tyres prematurely.

Climate

From the wet, mild winters of the North Island to the potential snow and ice in the South Island's alpine regions, New Zealand's weather runs the gamut. Both intense UV exposure in summer and cold, damp conditions can affect the rubber compound in your tyres.

Driving style

Your habits behind the wheel play a major role in how long your tyres will last. Aggressive acceleration, hard braking, and taking corners at high speeds scrapes rubber from the tread, which leads to faster and often uneven wear.

Tyre pressure

Driving with tyres that are either overinflated or underinflated is another cause of premature wear. Incorrect pressure alters a tyre's 'contact patch' on the road. This can shorten potential lifespan and compromise handling.

Maintenance habits

Neglecting basic care can also reduce tyre longevity. For example, not rotating your tyres regularly can cause uneven wear, with some parts of the tread wear faster than others.

Regular maintenance can help extend the life of your tyres and improve your driving experience.

1. Maintain correct tyre pressure

Always keep your tyres inflated to the pressure recommended by your vehicle’s manufacturer. You can find this information on a placard, usually located inside the driver's side door jamb, in the glove box, or on the fuel filler door. Check your tyre pressure at least once a month when the tyres are cold and before any long trips.

2. Rotate your tyres regularly

To promote even wear, rotate your tyres every 8,000 to 10,000 kilometres. Regular rotations help distribute wear evenly among all tyres, promoting balanced handling and extending the overall life of the set.

3. Check wheel alignment and balancing

If you notice your car pulling to one side or feel vibrations in the steering wheel (for front tyres) or your seat (for rear tyres), your wheels may be misaligned or unbalanced. We recommend having your wheel alignment checked when fitting four new tyres and then every 12,000 to 15,000 kilometres after that. It's also important to have the wheel alignment checked when buying a new car, as not all dealers include this as part of their pre-delivery service.

Correcting wheel alignment prevents uneven tread wear, especially on the inner or outer edges of the tyre, which is a common cause of premature replacement.

4. Drive smoothly

Avoid harsh acceleration, sudden braking, and high-speed cornering. Smooth driving extends tyre longevity and improves fuel efficiency and overall vehicle safety.

5. Store tyres properly

Properly store any tyres that are not in use, such as a seasonal set. Clean them, bag them, and store them upright in a cool, dry, dark place to prevent the rubber from cracking or degrading. Rotate the tyres periodically to avoid flat spots from developing.

MICHELIN is committed to engineering tyres that deliver exceptional performance and a long service life. Thanks to advanced technologies, our tyres are designed to provide safety and durability from the first kilometre to the last.

EverGrip™ Technology

Found in our touring and all-season ranges, Water EverGrip Technology features expanding rain grooves and a high-traction rubber compound. As the tyre wears, these grooves widen to maintain effective water evacuation, ensuring excellent wet grip throughout the tyre's service life.

MaxTouch Construction™

This construction method optimises the tyre's contact with the road, distributing the forces of acceleration, braking, and cornering evenly across the tread. This reduces wear and helps to extend tread life.

Silica-based compounds

Our advanced rubber compounds often include silica, which helps reduce rolling resistance for better fuel efficiency while also improving the tyre’s resistance to wear.

Reinforced sidewall design

For SUV and light truck tyres, a strong sidewall design provides added protection against cuts and impacts from curbs or rough terrain, which helps increase durability.

How do you know when to replace your tyres? While proper maintenance extends their life, all tyres eventually need to be replaced. In New Zealand, you must replace your tyres when the tread depth reaches the legal minimum of 1.5mm, though replacing them sooner ensures better wet-weather safety.

Look for these signs that it's time for a new set:

• Visible cracks, cuts, or bulges on the sidewall.

• Exposed cords showing through the rubber.

• Persistent vibrations or noise that isn't resolved by balancing or alignment.

• Tyres that are more than 10 years old, based on their manufacturing date, as the rubber can become brittle and unsafe, even if there is still tread left.

From advanced tread designs to innovative rubber compounds, Michelin tyres are engineered for superior tyre longevity. You can count on excellent safety, comfort, and performance throughout their life.
