Tire Problems

  • Can I drive on a flat tire that does not have run-flat technology?

    No. Michelin does not recommend driving on tires without Run Flat technology. Michelin Run-Flat tires have reinforced sidewalls designed to support the load of the vehicle in case of a pressure drop and allow continued driving for up to 50 miles (depending on road and driving conditions) at a maximum speed of 50 mph. Standard tires do not have this technology.

  • What are road hazard injuries?

    Road hazard damage is damage that occurs when a tire fails as a result of a puncture, bruise or break incurred during the course of normal driving on a maintained road. Nails, glass and potholes are the most common examples of road hazards.

    Avoid running over objects (e.g. potholes, rocks, kerbs, metal and glass, etc.) which may cause internal tire damage. Internal damage, not visible without demounting the tire, may be caused when a tire runs over an object. Continued use of a tire that has suffered internal damage (which may not be externally visible) can lead to dangerous tire failure. Determination of suspected internal damage requires demounting the tire from its rim and examination by a trained tire personnel.

  • What are the causes of centre tread wear?

    When the centre tread wears faster than the adjacent tread surfaces, possible causes include over inflation for load carried, rim width too narrow, misapplication, smooth wear after spin-out, improper tire rotation practices, aggressive acceleration or under-inflation for certain tire types, such as performance tires.

    If the tread depth is at or below 1.58 mm (2/32") in any groove or if cord material or under tread is exposed, the tire must be replaced. If sufficient tread remains, verify the proper rim width and vehicle fitment as well as verifying/adjusting inflation pressures, then rotate the tires for maximum wear.

  • What can cause my tire to show One-Sided Shoulder Wear?

    When the shoulder of the tread on one side of a tire wears faster than the adjacent tread surface, this can result from a variety of conditions, such as front and/or rear misalignment (example, toe or camber), loose or worn suspension components, hard cornering, improper tire-rotation practices, misapplication, high crown roads or non-uniform mounting.

    If the tread depth is at or below 1.58 mm (2/32") in any groove or if either cord or under tread is exposed, the tire must be replaced. If sufficient tread remains, verify that the tire has been properly mounted, then rotate the tires for maximum wear.

  • What can cause my tire to wear in more than one spot around the circumference?

    When tread is worn in one or more spots around the tire circumference, this can indicate brake lock/skid, improper balance, localised underlying separation, loose/worn suspension components, improper bead seating/mounting, progression from initial tread cut/chip/road hazard injury or chemical contamination. Surface texture may have initially shown abrasion marks from the tire sliding on the road, but the surface may have since worn smooth.

    When the tires with a flat spot are used in a dual application. you may consider rotating one tire 180 degrees in relation to the flat spot on the other tire.

    If the tread depth is at or below 1.58 mm (2/32") in any groove or if either cord or under tread is exposed, the tire must be replaced.

    When the cause of the flat spot is not apparent, your tre dealer should contact our Consumer Care Department.

  • What can cause my tire tread face to show one rib higher than the other?

    Feathering is a condition when the edge of each tread rib develops a slightly rounded edge on one side and a sharp edge on the other. The most common causes of feathering are incorrect toe-in setting or deteriorated bushings in the front suspension. The toe setting should be as close to 0 as possible for the optimum wear. 

    The tires should be inflated to the pressure as indicated on the sticker on the inside of the driver’s door. The vehicle manufacturer has determined this pressure is optimal for load, ride, handling, rolling resistance and tread-wear performance.

  • What can cause the sidewall of my tires to start turning a brownish colour?

    The brownish colour on the sidewall of your tires is not a defect. The source of this discolouration can be varied. One possibility is that the tires contain an anti-ozone agent in their rubber compounds to slow down the ill effects of exposure to ozone in the air. This anti-ozone ingredient will migrate to the surface of the rubber and leave the appearance of a brownish dust. This is completely normal and technically is no cause for concern. In time, depending on usage, it will disappear.

    Other possibilities for discolouration can be simply dust that is picked up from normal driving or brake dust which is generated by the abrasion of the brake pads against the brake rotor. This latter condition is more prevalent when the brakes are new or have recently been relined. In all cases, we recommend that you continue to clean your tires with mild soap and water.

  • What causes a tire to wear out?

    Tread-wear or life expectancy is determined by many factors:
    Driving habits and style of driving, geographical location, type of vehicle, type of tire, how the vehicle is maintained and how tires are maintained, etc.

    As a result, mileage expectancy is impossible to determine.

    Our Limited Warranty covers defects in workmanship and material for the life of the tread or six years from the original date of purchase, whichever occurs first. We offer no mileage warranty on the tires that were originally equipped on your vehicle.

    We suggest that you have the tires/vehicle inspected by a participating tire retailer in your area to determine if there is perhaps a mechanical or maintenance issue that could be contributing to a rapid or irregular wear pattern.

    Your satisfaction is important to us. Please have the dealer contact us with the tire inspection as we are willing to offer you assistance with your concern

  • What causes sidewall Indentations on my tire?

    The condition, sometimes referred to as sidewall undulations, is a common characteristic of radial tire construction is are purely a visual characteristic and will not affect the performance of the tire. These indentations are more noticeable in larger/wider radial-ply tire sizes and become more visible with higher inflation pressures. The joining of the ply material in the sidewall area may cause a slight indentation or wavy appearance on the sidewall surface of the tire when it is inflated. However, if bulges, rather than indentations appear on the sidewall of the tire, or if there is any question concerning any sidewall indentations, please contact a tire dealer for a tire inspection.

  • What could be the cause of my tires making a loud noise?

    Noise is most commonly due to an uneven or irregular wear pattern that has developed on the tires. 

    We suggest that you have the tires inspected by a participating tire retailer in your area. To find the dealers near you, refer to the Yellow Pages of your telephone book or utilise the Dealer Locator on our website.

  • What should I do if I notice a vibration?

    Vibration is an indication that your car has a problem that needs attention. The tires, steering system and suspension system should be checked to help determine the possible cause and correction of the vibration. If left unattended, the vibration could cause excessive tire and suspension wear. It could even be dangerous. Authorised Dealers offer expert diagnosis and repair.
