Have you ever wondered to the usefulness of this succession of figures and letters on the side of your tire? So this article is for you! Dimensions of tires, charging, speed, production date … you will be unbeatable on the subject! So take the time to read more and become the Pro Tire! Perfect to impress friends, right?!
Read the size of a tire
Let it be said, the installation of a bad tire is lost in advance … the size of the tire, indicated on the side, is essential when you want to change it and therefore not be exchanged by ordering the tires! The width is expressed in millimeters, the diameter of the inch edge while the height of the tire is expressed as a percentage compared to the width of the section … the brushes enough enough!
255: tire width in a millimeter (mm)
45: oscillation height in % compared to the width (45 % of 255)
A: Radial structure of the tire
It is the most used structure! It is also possible to see the letter d incripto: older diagonal structure and less efficient (faster, less cheap lack of socket). Finally, 3rd possibility: registration B, «Bias with belt», a pneumatic structure of the «diagonal» type.
17: internal diameter of the tire also
91: charge index
In the example of a tire, the charge index corresponding to 91 is a mass indicator. Present in the vehicle use book, this index is one kilogram. Therefore, index 91 allows you to support up to 615 kg! (See the table below)
Did you know? You can increase the load index when loading the tires. This will allow you to bear more weight. But be careful … you shouldn’t take a wolf index lower than that of origin under the penalty of being verbalized …
W: Speed index
If you understand the charging index, you will easily understand the speed index. In fact, this index estimates the maximum speed that the tire can support by guaranteeing perfect safety in the vehicle. While the following table evokes, the W letter corresponds to a maximum speed of 270 km/h. This index follows the same logic as the loading index … a higher indicator as its original tire: yes, but a lower speed index: no! For safety reasons, it is important to respect these conditions!
Exception to the rule: if you opt for winter tires, you can choose up to 2 indexes at lower speed than the original tire. Since in winter we have guided more slowly than the summer season, the law allows this change!
Read the dowry of a rubber
Have you been fascinated by the numbers underlined in orange and have you not even noticed the code on the left? Still, you need to know the identity of your tire! In fact, these 5 indicators allow you to know where and when the rubber was made.
Point: Transport Department
DMOF: Production plant code
PA: dimensional code
1r: production code
2311: week and year of production
In this example, the tire was designed on 23rd week of 2011 or during the week of June 6, 2011. The date is mandatory on each tire!
Good to know: the more recent the tire is, the more efficient it is!
Distinguish
Winter … an inevitable and formidable season for most of the vehicle. The equipment begins with good tires appropriate depending on the season to avoid any risk of accident. Stop scams! In fact, your winter tires must prevail the mention «m+s», mud and snow (in the French «mud and snow»).
In addition, the 3pmsf logo, «3 Peaks Mountain Snow Flake» (in French «Three editing peaks and a snowflake»), offers better performance on difficult winter surfaces such as snow and ice. Therefore, this additional mention is recommended for winters and rough trips in mountainous areas.
Here, now you can read your rubber! And as you can see, the side of the tire says a lot … for this, we have selected only some criteria that seemed essential for us.
