The warranty covers tyre damage caused by any pointed or sharp objects (e.g. nail or broken glass) or by hitting the edge of a kerb or pothole.
Tyres bearing the star means you can be sure of travelling in safety. The tyres are developed in close collaboration between BMW and its leading tyre partners. They are adapted to the chassis of your specific BMW model. These tyres have demonstrated outstanding suitability in extensive tests. Only if a tyre provides characteristic BMW handling and fulfils the demanding BMW criteria on all tests is it awarded the BMW star.
Your benefit: Increased safety.
BMW Approved Star-Marked Tyres are available with run-flat technology.
Whether in a long tunnel or in the pouring rain at night on the road - a flat tyre can happen in the most unfavourable places. The remedy here is a self-supporting tyre with emergency running properties, so-called run-flat technology - another benefit of BMW Approved Star-Marked Tyres.
The run-flat technology makes it unnecessary to change a wheel right away, allowing the driver to continue to the nearest workshop, for example. Additional elastic inserts made of highly heat-resistant rubber mixtures in the sidewalls prevent the tyre from overheating and catching fire when it has lost pressure. Even with no pressure at all, the run-flat tyre allows a loaded vehicle to continue to travel a distance of approximately 80km at a maximum speed of 80km/h*.
Perfect driving response even in the event of complete pressure loss.
This tyre technology offers enormous safety reserves in the event of very sudden pressure loss.
When driving fast on winding roads in particular, this means considerably increased safety. When a conventional tyre is punctured, it is generally impossible for the driver to continue travelling. However, a car with run-flat tyres remains easily controllable and directionally stable even in this extreme situation. Powerful steering manoeuvres are not required since ABS, ASC and DSC still remain fully functional to support the driver.
*The maximum possible distance with a puncture is determined by the load and stress to which the vehicle is exposed during travel. In the case of average load, the possible distance is approx. 80 km.
Your benefit: Less consumption.
BMW Approved Star-Marked Tyres are also available with reduced rolling resistance.
Tyres are permanently deformed during travel. This uses up energy – and therefore increases fuel consumption and road noise. In BMW Approved Star-Marked Tyres with reduced rolling resistance, deformation is reduced by the use of special materials on the running surfaces and sides. This reduces fuel consumption and road noise – on every straight road and on every corner.
Know when your BMW needs new tyres.
The running surface of a tyre which makes contact between the vehicle and the road is barely larger than an open hand. This does not leave much area in which to transfer brake force. Therefore, it is crucial to have tyres in good working condition at all times in order to extend the life of your tyres.
Regardless of how well you care for your tyres, the time will come when you must replace them. You can always bring your BMW to your nearest BMW Authorised Dealer for a quick inspection. If you prefer to do it on your own, here are some simple pointers to help you learn how to check your tyres.
Tyres lose their integrity with age. Heat, sunlight, chemicals from the road and gases from the air cause tyres to corrode and oxidise, making them unsafe for use. However, new tyres which are properly stored and not fitted on the car are not exposed to these elements. They are considered new up to 5 years from production date.
As not all tyres wear evenly, you should periodically inspect every part of your tyres. Look for uneven wear and flat spot on the edge of the tread. Replace tyres that bulge on the sides. Visible wires signal that a tyre has gone too far.
As tyres roll over highways, the friction between them and the road wear down their treads. When tyres have inadequate tread depth, they will not grip the road well and can lead to unsafe driving conditions, especially in the rain. BMW recommends the minimum tread depth to be no less than 3mm.
Get a grip!
The state of your tyres is crucial to make sure you do not start skidding on a wet road. As tread depth decreases, there is an increasing risk of aquaplaning and braking distance becoming longer. Driving response is no longer optimum on wet roads even from a tread depth of more than 3 mm.
Brake response with different tread depths:
Cracking the tyre code.
The many different abbreviations on the side wall of a tyre are often confusing - even to experienced professionals. The diagram below provides an explanation of the most common elements.
*It is important that you check your speed index before buying tyres. Choosing a tyre with a lower rating than appropriate can invalidate your insurance and also compromise your safety. The speed index shows the maximum speed for which the tyre is approved.
