Understanding the Sidewall of Your Tyre...

Example: 195 55 R 6 87 V

195 - Means the tyre has a width of 195 millimetres.

55 - Is the height of the tyre sidewall as a percentage of the nominal section width.

R - Means the tyre has a radial construction, the most commonly used of three different types of tyre construction: cross ply, radial and bias belted.

16 - Means it fits a 16" diameter wheel..

87 - Is the load index. This identifies the maximum load capacity of a tyre when driven at maximum speed. Overloading a tyre, by carrying more weight than it is designed to or running at a lower than specified pressure can cause heat build up and blow outs. Load indexes for passenger cars usually range from 70 - 110 and the maximum load per individual tyre is shown in the table below

V - Is the speed rating. This represents the maximum speed that a tyre can sustain at full load. The example shown is rated for speeds up to 168mph. (See below for more info)

Other common speed ratings are:

Q - for cars with max speeds up to 100mph (160km/h)
R - for cars with max speeds up to 105mph (170km/h)
S - for cars with max speeds up to 113mph (180km/h)
T - for cars with max speeds up to 118mph (190km/h)
H - for cars with max speeds up to 130mph (210km/h)
V - for cars with max speeds up to 150mph (240km/h)
Z - for cars with speeds over 150mph (240km/h) 
W - for cars with max speeds up to 168mph (270km/h)
Y - for cars with max speeds up to 186mph (300km/h)

Understanding European Tyre Labels...

This is a EU Tyre Label,It's very similar to the EU Labels on other devices like fridges and washing machines
