Changing tires made easy!
To make changing your tires quick, easy, and safe, we've put together a brief summary of the most important points. The functions of a tire are often underestimated—despite the fact that it's the only link between the road and the vehicle and is constantly exposed to extreme stress.
Be it braking or acceleration forces, high centrifugal forces, grip on snow and ice or even the vehicle's weight. Winter tires naturally have a softer rubber compound and (usually) more tread than summer tires. Who hasn't had the experience of missing the switch from summer to winter tires and then realizing that the tires don't grip as well as they should? People often underestimate the huge temperature fluctuations between day and night, especially in autumn and spring. It's not uncommon for temperatures to be +20°C during the day and then freeze overnight. When you then notice on your way to work in the morning that the road is icy (especially bridges or roads through the forest), it is unfortunately often already too late. That's why we recommend planning a tire change a little too early rather than too late.
The tread depth of a winter tire (M&S tire) must be over 4.0 mm. Below this depth, the tire loses its winter suitability and is no longer legally considered a winter tire. The tire itself should not be older than 6 years and must be properly disposed of at this point, even if the tread depth is still sufficient. Tires age even without use. Braking distances become longer, grip decreases, and, last but not least, the risk of tire damage increases. You can tell how old your tire is by the DOT number directly on the tire.
When replacing tires, it is recommended to install four of the same type. Mixing summer and winter tires is not permitted in winter (and is equally unadvisable in summer); it significantly impairs handling and promotes increased wear. Tires should always be replaced on an axle-by-axle basis, and tires with better tread should always be installed on the rear axle – this is known to be responsible for directional stability.
When tightening the wheels, be sure to use the correct torque and a torque wrench. Check that the wheel bolts are tight and straight after tightening and check again after about 50 kilometers. Otherwise, the wheel could pop off, and an accident is inevitable. Of course, your health should also be a top priority when changing the wheel.
A (shunting) jack is worth its weight in gold – it makes work easier and provides secure support. However, the jack often found in the trunk should really only be used in the event of a breakdown, as these are usually rather delicate. Remember: If the car slips off some kind of adventurous construction while changing a wheel, you risk not only damage to the vehicle but also your own health!
Only use and purchase tires approved for your vehicle type; otherwise, your vehicle's operating license will be invalidated. Tire pressure can be slightly higher rather than lower; tires that are too "soft" increase wear and fuel consumption.
