FAQ

Tire Care and Maintenance

  • Do my driving habits affect the life of my tires?

    Yes. Here are several tips to help increase the life of your tires:

    • Don’t speed. High speeds can generate excessive heat, which can increase the rate of tire wear. Drive at the safe, legal speed limit.
    • Avoid fast turns on curves and around corners.
    • Avoid fast starts and panic stops.
    • Don’t ride on the edge of the road or drive over kerbs, potholes or other obstructions.
  • Do my new tires require special treatment?

    Special treatment is not required for your new tires. However, drive carefully while you get accustomed to them. You may feel a difference when accelerating, braking, cornering or possibly driving in wet conditions.

  • How do I take care of my new tires?

    Properly maintained tires can help to give you a more comfortable ride and a longer tread life. So:

    • Check your tire pressure monthly with a tire-pressure gauge (and make sure that the tires are cold – at least 3 hours after driving).
    • Check your tires frequently for any cuts, snags, punctures, any other injury, or irregular tire wear.
    • At the first sign of irregular tread-wear, have your alignment checked.
    • Make sure that the tires are balanced when they are mounted on the wheels.
    • Rotate your tires following the schedule in your vehicle owners manual or as required by the tire manufacturer’s warranty.

  • How many kilometers will I get out of my tires?

    Many factors can affect the tread life of your tires, such as:

    • Tread compounds
    • Construction features
    • Vehicle application
    • Tire maintenance
    • Geographic conditions
    • Atmospheric conditions
    • Driving habits
    • And more

    That’s why exact mileage is impossible to predict. Take special care when braking, accelerating and cornering, etc., to help increase the life of the tire. (Owning tires with Michelin’s technology doesn’t hurt either.) If you have concerns about the rate of wear on your tires, consult your local authorised Michelin retailer.

  • How should I care for tires that I have in storage?

    Tires should be stored in a cool place away from direct sunlight, sources of heat and ozone such as hot pipes and electric generators. Exposure to these elements during prolonged periods of time will exhaust the tire's oxidation and weathering agents within the rubber compounds and result in cracking. Be sure that the surfaces on which the tires are stored are clean and free from grease, fuel or other substances that could deteriorate the rubber.

    For mounted tires inflate at, but no higher than, the recommended air pressure. Store vehicles on blocks to remove the load from the tires.

  • Is it safe to repair a flat tire?

    If a tire loses all or most of its air pressure, it must be removed from the wheel for a complete internal inspection to be sure that it's not damaged. Tires that are run for even short distances while flat are often damaged beyond repair. Most punctures, nail holes, or cuts of up to 0.6 cm (1/4 inch) - – confined to the tread - – may be satisfactorily repaired by trained personnel using industry-approved methods. Don't repair tires with tread punctures of larger than 0.6 cm (1/4 inch), or any sidewall puncture. Also, never repair tires which are worn below 1/16 inch tread depth. Your best bet is to make sure that your spare tire is always ready to do the job. Check it regularly for proper air pressure and be sure that it is in good shape. If your car is equipped with one of the several types of temporary spares, be sure to check the spare tire's sidewall for the correct inflation pressure, speed and mileage limitations. See your dealer for expert tire repair.

  • Is there a time period on breaking in my new tires?

    New tires have to be driven for a few hundred miles on dry roads to rid the tread of the parting agents and antioxidants applied during production. Not until the tread has been slightly roughened will the tire be able to make its true gripping power felt.

  • Is there a way to tell when I need new tires?

    Tread-wear indicators ("wear bars") are located at the base of the main grooves and are equally spaced around the tire. The tread-wear indicators, which look like narrow strips of smooth rubber across the tread, will appear on the tire when that point of wear is reached. When you see these wear bars, the tire is worn out and it's time to replace the tire. Always remove tires from service when they reach a remaining tread depth of two thirty-seconds of an inch (2/32").

  • Must I replace my present tires with the same size tires?

    Never choose a smaller size than those that came with the car. Tires should always be replaced with the same size designation - – or approved options – as recommended by the vehicle manufacturer or authorised dealer

  • Should my tires be balanced?

    Proper balancing is critical for optimal vehicle performance, especially at today's higher motorway speeds. When tire and wheel assemblies are unbalanced, a vibration can result from wheel and assembly shimmy (shaking from side to side) or wheel assembly tramp (tire and wheel hopping up and down). Therefore, it is important that these assemblies are in both static and dynamic balance

  • What is proper alignment?

    A vehicle is said to be properly aligned when all suspension and steering components are sound and when the tire and wheel assemblies are running straight and true. Proper alignment is necessary for even tread wear and precise steering. Uneven front or rear tire wear, or changes in your vehicle's handling or steering response (i.e. pulling to one side) can indicate misalignment. Many vehicles today are equipped with rear suspensions that can be adjusted for alignment. Your vehicle many need a "front-end" alignment or a "four-wheel" alignment, depending on the symptoms you are experiencing. The moderate cost of having your vehicle aligned can more than pay for itself in tire mileage, performance and comfort.

  • What is your opinion on the use of nitrogen in tires?

    Nitrogen is an inert gas. It is simply dry air with the oxygen removed (air contains nearly 79% Nitrogen). The physical properties of nitrogen reduce the pressure loss due to the natural permeability of the materials of the tire. Unfortunately, there are other possible sources of leaks (tire/rim interface, valve, valve/rim interface and the wheel) which prevent the guarantee of pressure maintenance for individuals using air or nitrogen inflation. Tires manufactured by Michelin are designed to deliver their expected performance when inflated with air or nitrogen, as long as the user respects the pressures recommended by the vehicle manufacturer on the vehicle's placard or those of the tire manufacturer. Whether they are inflated with air or nitrogen, regular pressure maintenance remains critical because under-inflated tires lead to:

    • A reduction in road holding
    • A reduction in wet traction capability
    • An increased sensitivity to road hazards
    • A reduction in tread-life
    • An increase in fuel consumption
    • A reduction in tire life due to excessive heat from over deflection
  • What should I look for when inspecting my tires?

    In addition to performing regular maintenance, you must also keep an eye out for potential problems that might affect your tires. Regular inspections can help you prevent tire trouble, and keep you rolling safely down the road. When inspecting your tires, look for:

    Uneven tread wear : This can include more wear on one tread edge than the other, a rippled pattern of high and low wear, or exposed steel wire. Uneven wear can be caused by problems such as under-inflation, misalignment and improper balancing.

    Troublemakers : Check for small stones, pieces of glass, bits of metal and other foreign objects that might be wedged into the tread, and carefully pick them out. They can cause serious problems if they are pushed farther into your tire as you drive.

    Damaged areas : Cracks, cuts, splits, punctures, holes and bulges in the tread or on the sides of the tire can indicate serious problems, and the tire may need to be replaced.
    Slow leaks. tires lose some air pressure (about 2 psi) over the course of a month or so, but if you find that you have to add air every few days, have the tire, wheel and valve checked—and if necessary, repair or replace the tire.

    Valve caps : Those little caps on your tire’s valve stem keep moisture and dirt out, so make sure they are on all your tires. Also, when you have a tire replaced, have a new valve stem assembly installed at the same time.

    Driving on a damaged tire can be dangerous. If you see something that you’re not sure about during your inspection, have it examined by your tire dealer. Any time that you see damage to a tire, don’t drive on it – use a spare if you need to go somewhere. And finally, 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, and/or you suspect possible damage to your tire or vehicle, 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.

  • When should I check my air pressure?

    Air pressure in tires, including the spare, should be checked at least monthly and always before extended driving. Tires should be checked when they are cold (at least three hours after the vehicle has been stopped and before it is driven more than one mile or two kilometres). Do not reduce pressure when tires are hot; use an accurate air-pressure gauge to check pressure and maintain it at the level recommended on the vehicle tire vehicle placard or in the vehicle owner’s manual. Under-inflation produces extreme flexing of the tire and builds up heat to the point that tire failure may occur. Over- or under-inflation may adversely affect vehicle handling. Cold tire pressures should never be higher than the limit moulded on the sidewall.

  • Where should I mount the tires if I only purchase two?

    Michelin recommends replacing all four tires at the same time, however if replacing only two new tires, be sure that the new tires are the same size and tire type as the current tires and that the dealer always installs the new tires on the rear axle of the vehicle.

    Why Put the Two New Tires on the Rear Axle?

    • The New tires will provide better wet grip than your half-worn tires.
    • It will help to reduce the potential for the vehicle to fish-tail and lose stability in wet conditions
