The most important tag on tire it is usually located on the side. Example, if it says on the tire 205 / 55R16 91V, the meaning of the tags is as follows:
205 - indicates the width of the tire in millimeters, and when we say width, it means tread.
55 - tire profile (series) - the ratio between the height of the side wall and the width of the tread (tread) expressed in percent. In this case, the height is 55% of the width of the tire.
R is the designation for a radial construction. Most of today's passenger vehicles use radial tires, which means they are more resistant to bumps in the road and mean lower fuel consumption.
16 -Wheel diameter (in inches - inches).
91 indicates the load capacity index of the tire, ie what is the maximum load of the tire. There are many load indices and a table that is associated with it and indicates the maximum load. 91 indicates a maximum tire load of 615 kilograms.
Load capacity [kg]
Load capacity [kg]
V is the speed index label. This specifically means the maximum speed the tire can withstand at maximum load. A table is also attached to these marks, so the V mark means that it can reach speeds of 240 kilometers per hour at a maximum load of 615 kilograms. There are also the following tags:
km / h
km / h
In addition to all of the above, there are additional tire labels, which are:
RF - abbreviation for reinforced, meaning that the tire is reinforced.
ROF or RFT - the abbreviation for Run On Flat and Run Flat, which means that we can continue to drive on these tires even if they are pierced, however, we must reduce the speed to a maximum of 90 km / h and must not exceed 160 kilometers with such tires.
XL - abbreviation for Extra Load, indicates a tire made for heavy loads.
M + S - an abbreviation for 'mud and snow', ie for tires that are specially made for driving on mud and snow. This label can be found on either winter or all-season tires.
TT - abbreviation for Tube Type, and denotes tires that have an inner tire.
TL - the abbreviation for Tubeless, which stands for tires that do not have another tire inside, and most of today's car tires are like this.
DOT - abbreviation for production date. This usually comes with a number. If it says DOT 2510 it means that the tire was manufactured in the 25th week of 2010.
C - This mark is on light truck tires.
TWI - abbreviation for Tread Wear Indicator, which indicates the tire wear indicator, ie tells when the tire needs to be replaced for wear.
E 10 - the mark for the European type-approval number, with the number of the country code.
TEMPERATURE - an indicator of how much the tire is resistant to an increase in temperature on the road, with C being the lowest indicator and A the highest (they react best to an increase in temperature).
TRACTION - the ability of the tire to stop in the wet.
TREADWEAR - Indicates tread wear indicator on the tire and shows how long one track on the tire will last longer than the others given the same road conditions.
TUBELESS - label for tires that do not have another inner tire filled with air.
