Tyre Problems

  • Are punctures/cuts covered under the warranty?

    Our warranty covers defects in workmanship and material for the life of the tread or 3 years from date of purchase (if tyre is purchased within 3 years from date of manufacture) or 6 years from date of manufacture (if tyre purchased is more than 3 years from date of manufacture), whichever occurs first. We do not cover tyres that are damaged as a result of road hazards, cuts, punctures, impact, Tread Aggression, uneven wear or quick wear, vehicle irregularity, etc. For complete details.

  • Can I replace a Run-Flat tyre with a standard one?

    No. Michelin does not recommend Changing run flat tyres with standard tyres. The Michelin Run Flat tyres have reinforced sidewalls designed to support the load of the vehicle in case of a pressure drop and allow continued driving for up to 80 km (depending on road and driving conditions) at a maximum speed of 80 km/h. Standard tyres do not have this technology.

  • Is a Bubble/ 'Bulge on the sidewall of my tyre covered by your warranty?

    A bulge or bubble in the sidewall is sometimes the result of damage from coming in contact with a curb, pothole or other object. Evidence of this damage can be:

    • a scuff mark on the sidewall near the bubble
    • a dent or damage on the wheel above the bulge
    • a cut or bruise on the inner liner of the tyre in the vicinity of the bulge (the tyre must be demounted in order to inspect the inner liner).

    A tyre that sustains any of the above injuries is damaged and is not covered under warranty.

    However, your satisfaction is important to us and we request that you take the tire into a participating dealer for inspection to determine if warranty coverage applies.

  • What are road hazard injuries?

    Road hazard damage is damage that occurs when a tyre 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. chuckholes, rocks, curbs, metal, glass, etc.) which may cause internal tyre damage. Internal damage, not visible without demounting the tyre, may be caused when a tyre runs over an object. Continued use of a tyre that has suffered internal damage (which may not be externally visible) can lead to dangerous tyre failure. Determination of suspected internal damage requires demounting the tyre from its rim and examination by a trained tyre personnel. Complete details are available here.

  • What are the causes of center tread wear?

    When the center 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 tyre rotation practices, aggressive acceleration or under inflation for certain tyre types, such as performance tyres.

    If the tread depth is at or below 1.66 mm in any groove or if cord material or under tread is exposed, the tyre must be replaced. If sufficient tread remains, verify proper rim width and vehicle fitment as well as verify/adjust inflation pressures, then rotate the tyres for maximum wear.

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

    When the shoulder of the tread on one side of a tyre 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 tyre rotation practices, misapplication, high crown roads or non-uniform mounting.

    If the tread depth is at or below 1.6mm any groove or if either cord or under tread is exposed, the tyre must be replaced. If sufficient tread remains, verify that the tyre has been properly mounted, then rotate the tyres for maximum wear.

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

    When tread is worn in one or more spots around the tyre circumference, this can indicate brake lock/skid, improper balance, localized 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 tyre sliding on the road, but the surface may have since worn smooth.

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

    If the tread depth is at or below 1.6mm in any groove or if either cord or under tread is exposed, the tyre must be replaced.

  • What can cause my tyre 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 based on the vehicle manufacturer’s recommendation.

    The tyres should be inflated to the pressure as indicated on the sticker on the inside of the driver’s door or on the inside of fuel lid. 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 tyres to start turning a brownish color?

    The brownish color on the sidewall of your tyres is not a defect. The source of this discoloration can be varied. One possibility is that the tyres 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 discoloration 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 tyres with a mild soap and water occasionally. It is recommended to not use pressure jets or strong soap solutions to clean the tyre.

  • What causes a tyre to wear out?

    Treadwear or life expectancy is determined by many factors:
    Driving habits and style of driving, geographical location, type of vehicle, type of tyre, how vehicle is maintained, how tyres 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 3 years from date of purchase (if tyre is purchased within 3 years from date of manufacture) or 6 years from date of manufacture (if tyre purchased is >3 years from date of manufacture), whichever occurs first. We offer no mileage warranty on the tyres that were originally equipped on your vehicle.

    We suggest that you have the tyres/vehicle inspected by a participating tyre 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. If you need assistance locating a participating tyre retailer, please visit our website or call our toll free number at 1800 103 6424.

  • What causes sidewall Indentations on my tyre?

    The condition, sometimes referred to as sidewall undulations, is a common characteristic of radial tyre construction and is purely a visual characteristic and will not affect the performance of the tyre. These indentations are more noticeable in larger/wider radial-ply tyre 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 tyre when it is inflated. However, if bulges, rather than indentations appear on the sidewall of the tyre, or if there is any question concerning any sidewall indentations, please visit your nearest Michelin authorized dealer. If you need assistance locating a participating tyre retailer, please visit our website or call our toll free number at 1800 103 6424.

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

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

    Sometimes Noise could be a perception or feeling one may perceive especially after changing to a new set of tyres. We suggest that you have the tyres inspected by an authorized Michelin dealer in your area.

  • What could cause my tyre to wear on the Inside and outside shoulders?

    The cause of Inside andOutside shoulder wear is normally due to improper inflation pressure, hard cornering, frequent mountain driving, driving on crowned roads, improper tyre rotation practices or a rim width too wide for the tyre.

    If the tyre's tread depth is at or below 1.6 mm in any groove or if cord material or under tread is exposed, the tyre must be replaced. If sufficient tread remains, verify proper rim width and vehicle fitment as well as verify/adjust inflation pressures, then rotate the tyres for maximum wear.

  • What could cause my tyre tread to come off?

    A separation between the tread rubber and the underlying belt may be the result of cumulative poor inflation maintenance, improper inflation pressure, repair or storage, excessive load, speed or heat, prior impact damage, tread cut or puncture or run flat.

    A tyre exhibiting this condition should be permanently removed from service.

  • What does it mean if my tyre has shredded into pieces?

    The tyre industry refers to tyres in this condition as "run flat" which refers to a tyre that has lost air, whether it is from a slow loss or an immediate loss, and then subsequently run on. As the tyre continues to operate or "run" with significant amount of air loss, it reaches the "runflat" stage, where serious internal damage is caused by the excessive deflection of the casing. If the air loss continues, the inside of the deflected sidewall can actually rub against itself. When the internal abrasion weakens the casing sufficiently a blowout can occur. Additional damage is often done by the relatively sharp rim flange cutting into the fully deflated casing as it is driven after the blowout, even in the short distance it takes to drive the vehicle to the side of the road.

    We are not indicating that the tyre was not maintained, but simply that it lost air. Some of the many factors which can cause a tyre to lose its inflated air pressure are penetrations, cuts, snags, impact breaks, valve stem leaks, incorrect mounting, just to name a few. While it may not be possible to pinpoint the cause of initial air loss, we know the outcome is underinflationdamage.

    A tyre exhibiting this condition should be permanently removed from service.

  • What does it mean when my tyres start to show signs of aging, ozone cracking or weather cracking?

    The life of a tyre cannot be measured by kilometres alone. tyres are composed of various types of material and rubber compounds, having performance properties essential to the proper functioning of the tyre itself. These component properties evolve over time. For each tyre, this evolution depends upon many factors such as weather, storage many factors such as weather, storage conditions, and conditions of use (load, speed, inflation pressure, maintenance etc.) to which the tyre is subjected throughout its life. This service-related evolution varies widely so that accurately predicting the serviceable life of any specific tyre in advance is not possible.

    It is impossible to predict when tyres should be replaced based on their calendar age alone. However the older a tyre the greater the chance that it will need to be replaced due to the service-related evolution or other conditions found upon inspection or detected during use.

    While most tyres will need replacement before they achieve 10 years, it is recommended that any tyres in service 10 years or more from the date of manufacture, including spare tyres, be replaced with new tyres as a simple precaution even if such tyres appear serviceable and even if they have not reached the legal wear limit.

  • What is Cupping?

    Cupping can be attributed to bent or worn suspension parts, wheel misalignment, an imbalance of the tyre/wheel assembly, etc. Once this type of wear pattern has occurred, it is irreversible and the tyres will continue to wear unevenly.

  • What should I do if I notice a vibration?

    Vibration is an indication that your car has a problem that needs attention. The tyre-Wheel assembly, 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 tyre and suspension wear. It could even be dangerous. Authorized Dealers offer expert diagnosis and repair. If you need assistance locating a participating tyre retailer, please visit our website or call our toll free number at 1800 103 6424.

  • What should I do if my tyres wore too fast?

    An inspection of your tyres must be performed by a participating Michelin dealer to ascertain the cause for low tye mileage. You may also need to get the vehicle inspected by an OEM authorized service workshop to rule out any vehicle irregularity.
    Factors that can affect rapid tyre life are:

    • Tyre maintenance (inflation and rotation)
    • Vehicle maintenance (alignment and suspension)
    • Driving styles and habits
    • Materials used in road surfaces
    • Topography of the area the vehicle is driven in.
  • What should I do if my vehicle is pulling to one side?

    Incorrect alignment settings can adversely affect handling. Tolerable camber, caster and toe settings can be verified by a print-out from your alignment/tyre shop or vehicle dealer.

    If the tyres are evenly worn, the alignment is in order and there is still a pull, the front tyres should be criss-crossed (as long as they are not a directional tread design) to see if the pull changes directions.

    This should be performed by a participating dealer.

  • What should I do if the cords on my tyres are visible?

    Cord material may become visible at the base of tread grooves or slots due to under inflation, misalignment, loose/worn suspension components, hard cornering, improper tyre rotation practices, misapplication, high crown road or non-uniform mounting.

    A tyre exhibiting this condition should be permanently removed from service.
