Do I need new tires ?
What are the basics?
There is no way to tell exactly how long a tire lasts. The lifespan and mileage of a tire depends of a combination of factors: its design, the driver’s habits, the climate, the road conditions and the care that's put into the tires.
A few milestones and tips:
Keep five years in mind
After five years or more in use, your tires should be thoroughly inspected at least once per year by a professional.
Ten years is a maximum
If the tires haven't been replaced 10 years after their date of manufacture, as a precaution, Michelin recommends replacing them with new tires. Even if they appear to be in usable condition and have not worn down to the tread wear indicator. This applies to spare tires as well.
Proper care expands a tire’s lifespan
You can increase your tire's longevity by maintaining the correct air pressure, performing regular tire rotations and vehicle maintenance.
For original equipment: follow the vehicle manufacturer’s tire replacement recommendations.

What damages tires?
- Wear and Damage
- Potholes, obstacles, curbs, sharp objects, speed bumps
- Extreme temperatures
- Rain, snow, and ice
- Oil, grease, and other chemicals
- Strong sunlight and ozone
- Quick starts and emergency braking
- Driving on damaged roads
- Failure to notice a change in handling, noise, or vibration
- Failure to consult a professional when something changes
Neglecting basic tire maintenance:
- Air pressure
- Not routinely checking for wear or damage
- Alignment and rotation
- Neglecting to get a professional tire inspection in the event a tire has been impacted or sustained damage
- Not balancing tires after they are installed
- Improper tire storage
- Use of sealants that have not been approved
- Using summer tires on snow and ice
- Mixing tire types
- Using tires on damaged wheels
- Using wheel and rim sizes that are not compatible
- Fitting tires that do not have a speed capability and load index at least equal to or higher than those originally specified by the vehicle manufacturer
- Reinflating a tire that has been run flat or seriously underinflated
- Using a spare tire of a different size at speeds in excess of 80 kph
Is my tire worn out?
We recommend replacing your tire if:
- The tread is worn beyond the recommended tread depth levels
Inspect your tire regularly and look for:
- Uneven tread wear
- Shallow tread
- Troublemakers (rocks, nails, etc.)
- Damaged areas
- Damaged valve caps
Pay attention to the “feel” of your tires as you drive.
- A rough ride may indicate tire damage or excessive wear.
- If you notice vibrations or other disturbances while driving, immediately reduce speed, drive with caution until you can safely pull off the road and stop, and inspect your tires.
- If a tire is damaged, deflate it and replace it with your spare. If you do not see any tire damage and cannot identify the source of the vibration, take the vehicle to a tire dealer for a thorough inspection.
See a professional
- If you see something you’re not sure about during your inspection, have it examined by your tire dealer.
To identify a specific problem.
How do I inspect my tire?
Check your air pressure
- It’s quick and can prevent many problems
- Do it once a month
Check the tread wear with one of the three methods:
- With a tread depth gauge
- With the tread wear indicators
With the quarter test
- Put the edge of the coin into the tread, with the Queen going in head first.
- If the top of the Queen's head is covered by tread, that's good. If the top of her head is entirely visible, it's time to replace the tire.

When should I inspect my tires?
- Once every month
- Before you go on a long road trip.
Next steps :
- Any visible perforation, cut or deformation must be checked thoroughly by a tire professional.
- Only a tire professional can tell you if your tire can be repaired or has to be changed.
Spare tire: can I use it on a day-to-day basis?
Temporary spares have lighter construction to limit their weight on your vehicle so they don’t have the same speed or mileage capabilities. This could affect your vehicle’s stability. The only exception is if your spare tire is actually a 5th full-size tire that exactly matches the tires on your vehicle.
