Winter tires Guides
When should winter tires be put on?
As a rule of thumb to remember: From O to E, ie from October to Easter, go best with winter tires.
Once wintry conditions prevail, you should have winter tires on your auto. But what exactly is meant by "winter conditions"? That is also clearly stated in the Road Traffic Act. As a "winter conditions" and thus trigger the obligation for snow tires apply:
- Packed snow
- Ice or slippery frost
To be sure not to be surprised by a sudden onset of winter, it is recommended that winter tires be for sale by the autumn.
If you have two sets of wheels one for winter and one for summer, you will not even have to go to the shop to have winter tires put on. You just need a jack and wrench.
Summer and winter wheels ease the transition. The prerequisite is of course that not only two complete sets of tires, but also a double set of wheels is available: one for summer and one of a kind for winter tires.
If you have two sets of wheels (rims) no you can have one set with winter tires on as long as you have somewhere to store them. If stored properly they should last a few seasons.
Experts advise to replace the winter tires about every four years with new ones. Several factors can cause the tire quality to decline:
- Aging of the material
- Tire damage
Old, worn or even damaged tires pose a greater risk potential. Byordered online in advance, you can expect a big savings.
But how do I know if the winter tires from last year are still fit for next winter? Even if the tires seem to be fine on the surface, it is best to pay attention to two things: tread depth and DOT number.
How old are my tires? The DOT number provides that information.
Tires are made mostly of rubber. Over time, the material hardens, resulting in a poorer grip - the tire is then no longer any good. Therefore tires that have never been driven, will need to be discarded after about six or seven years.
But how do I know now how old my tires are actually? Furthermore are the DOT numbers reliable information? It is stamped on each tire on the flank. Next to the DOT number can be found all sorts of other numbers and letter symbols. For the tire age only the last four (highlighted by a border) figures are relevant. The first two digits reveal the calendar week; the last two the year of manufacture.
Detect wear: Measure tread depth
In order to identify tire wear at times, it is advisable to measure the tread depth at regular intervals. It is true that each tire also a so-called TWI, or Tread Wear Indicator. This abrasion indicator can be found next to a symbol of small triangles and the symbol TWI at the upper sidewall of the tire. Here are continuous webs to recognize the tire remains only a residual profile of 1.6 millimeters. It should now be changed urgently.
Although actually the highway code provides for only a minimum tread depth of just 1.6 millimeters - but experts agree that this is far too little. They recommend unanimously to mount new winter tires at a remaining profile of 4 millimeters.
In order to determine reliably whether the question 4 millimeters remaining tread are already achieved, it is therefore imperative periodically with a profile measuring device to check the tires. In a pinch, a coin also helps: If the edge concealed by the remaining profile, everything is in order. As soon as the can be seen, the tires must be changed.
The following brief overview summarizes the most important information and tips for measuring the tread depth once again:
- Tread depth 1.6mm
- TWI on tire wall
- 4.0mm Profile meter or euro coin
The profile of winter tires
Especially with winter tires a good profile is essential. Finally, the tires need to keep their grip not only in the wet but also in snow, slush and ice. For this they get from the manufacturers a special profile imprinted.
A winter tire tread consists of the following elements:
- Profile ribs
- Tread blocks
- Tread groove
- Profile blades
A special feature of the profile of winter tires are also the slats: small cuts in the tread blocks, often in zigzag shape. Thanks to this fine lamellae of winter tires retains a firm hold in slippery conditions.
How do I know a good winter tire?
The best and safest thing is to go with high quality, new tires through the winter. But how can I recognize a good winter tire? To navigate in the comfortable and safe areas, customers can check different quality features:
- Uniform symbols and markings of winter tires
- Quality standards of certain brands and manufacturers
- Independent tire tests
If you want to be sure that you are buying a good product, it is best to not just rely on one of those criteria but keep all three in mind.
Labelling of winter tires
Labelling of winter tires: Different quality standards
These can be recognized by the impression at the edge MS shortcuts, which occurs in the following variations:
The MS-labeling is current regulation according to the minimum standard to be met by the tire to make winter tires mandatory. In concrete terms, if you are driving in winter conditions with a tire which does not carry the MS symbol, you must pay a fine..
Customers are better advised to pay attention to the Alpine icon. Also called snowflake symbol, it shows the icon of a mountain with a snowflake. Only tires that can demonstrate in performance tests an above-average traction get the sign imprinted. Anyone who buys a winter tire with the Alpine symbol can be sure that the tire can cope with winter challenges.
