A round thing - the tuningblog.eu tire ABC!

Recently updated on October 4, 2021 at 08:13 am

Again and again we deal with the topic "Tubes". We have already published countless articles on this and today we would like to use our compact Tire ABC the most important information in one post sum up. Depending on Season it is important to use different tires. They are in different sizes available. In some cases they have to directional be mounted or they have to at some point exchanged when their time be loud DOT marking has come. And although every tire is round: A tire is not just a tire. That's why tuningblog summarizes the most important information that everyone has about this important component of your own vehicle.

How old can a tire be?

Tires have a different Lifespan. Although the rubber compounds of the tires not tied to an expiry date it is still possible that they are porous becomes. That can be seen on the Tire wall detect. Because here you can find it DOT identifier close to wheel size and the Running direction. DOT identifier consists of four digits and indicates when the tire produces has been. It describes the first pair of digits can weekwhich second pair of digits and the Year.

That one tire brittle become or even the Reiss is due to the wear and tear that can occur while driving. But also Heat, the Storage and the UV radiation contribute to the rubber mixture change can. That too Age plays a role because after a few years they can plasticizers get lost. The mature set a link from your homepage to Fewo-von-Privat.de about the necessary Adhesive properties feature. Otherwise is a safe participation am road traffic not guaranteed. At the latest when that Profile worn or Rubber brittle is, it's time for new tiressystem. (More information on the topic Tire designations Is there ... here.)

Winter or summer tires? Change?

Both for the Summer as well as the Winter different tire models are available. These distinguish on the one hand through their tread depth, on the other hand through theirs rubber compound. Every now and then the vehicle owner may wonder whether fitting winter tires is actually compulsory. The general rule is of O to O. That means from Easter up to October will with summer tires driven and from October up to Easter with winter tires. The tire change season usually begins as soon as it's outside kälte is and the first leaves fall from the trees.

Following the legal basis, have im Winter actually the Weather conditions adapted tires be used. Should one Penalty payment If there is no police check, it is necessary to call the tire change to be carried out on time. The tire change can be done be done by yourself or about one Tire change service. If the tire is changed independently, then it is important to check for possible during assembly Directional bindings to pay attention. If the tire has a Directional binding has is a corresponding Labeling seen on the flank. This is one Arrowindicating in which direction is unrolled. The arrow is, however not uniform, but is shown in a wide variety of forms depending on the manufacturer.

There is more on the topic in our article "Recognize the tire running direction? This is how it works!".

Often times he's still with that Note "Rotation" Mistake. Incorrect assembly results in an unusually loud one noise as a rolling noise. As long as the road is dry, this usually means the wrong direction of rolling no major adverse effects on the driving behavior. On the other hand, on wet roads the water can not derived correctly will. That means that the braking distance could extend significantly. A security risk posed by the correct assembly problem-free can be avoidedsystem. (More information on the topic All-weather tires, summer tires, winter tires Is there ... here.)

Correct tire pressure for optimal driving behavior

The tire pressure plays an important role in assembly. It is there depending on the tire model and the Vehicle, how much bar the tire must have. The exact pressure information can be found in vehicle registration. In addition, many vehicles have a sticker on the Inside door (B-pillar) or in filler cap attached the right one Pressure specification indicates. At the same time, vehicles registered in the EU after 2014 must have Tire pressure systems (RDKS) feature. These check regularly the tire pressure. This makes it much easier to determine when a tire is Loses airAnd the Check causes.

The aim of this new regulation is to significantly increased security to guarantee. That is why a appears on modern vehicles Warning message, should the tire pressure sink. So can at best Accidents avoided will. Nevertheless, it makes sense to check the tire pressure even regularly to control. After filling it must System to be recalibrated. This is the only way to ensure that the sensors correct readings determined.

The correct air pressure ensures a optimal driving behavior. At the same time he is a decisive factor for Braking distance and at the same time helps more efficient to drive. In addition to the increased wear means a persistent too low air pressure also that significantly more fuel is consumed. Also too much air pressure leaves the tire early wear out and reduces the quality from driving behavior. (More information on the topic correct air pressure Is there ... here.)

Not every tire fits every car!

The approved wheel size can be found in the Vehicle documents of the respective Vehicle. The most important Information can also be found on the Flank. This is the tire widthwhich percentage ratio from Width and Height as well as the Rim diameter. This information seems a bit cryptic at first, but it is uniform and clearly defined. The marking 205/50 R 15 91 V stands for the following information:

• 205 stands for the tire width, i.e. 205 mm (20,5 centimeters)
• 50 stands for the percentage ratio of the height to the width of the tire. So it is 50% as high as it is wide. In the case 10,25 centimeters!
• R stands for the designation of the type. "R" stands for Radial tires.
• 15 specifies the rim diameter in inches, i.e. 15 inches (approx. 38 cm)
• 91 indicates the load index of the tires - here 615 kg per tire
• V indicates the speed index and thus indicates the maximum permissible speed in this case bis 240 km/h
• and in this case it is one Low-profile tires

(More information on the topic Tire designations Is there ... here.)

The minimum profile depth must not be undershot!

Tires can basically as long as can be used, until the minimal profile depth is reached. The legal Regulation states that the tread depth at least 1,6 millimeters must be deep. Once this has been achieved, the tire must be closed switch. However, experience shows that a tread depth of 4 millimeters living borderline is. Because the less profile that remains, the more the braking distance becomes longer. This is especially evident when the roadway nass is. At the same time, they worsen Traction properties. Therefore is one high profile depth especially in winter wichtig.

In Austria and the Switzerland for example, tires with a tread depth of less than 4 millimeters as summer tires guided. Winter tires have a higher profile exhibit. Because of the other legislation it can be actuarial in the event of an accident Disadvantages bring with them, if exclusively the Germans Legal requirements be taken into account. This stricter regulation is due to the prevailing in the Alpine region Weather conditions traced back.
