How to Read a Tyre

There is a series of written information on the tyre´s sidewall which makes up its “identity card” and enables us to know the tyre’s size, its use limits, manufacturing details, etc. It’s fundamental to understand this information to make sure we are using the correct tyre.



205 – Section width of the tyre in millimeters (205 mm)

50 – Ratio between the height and the width of the section (this value means it measures 50% of the width, that is, approximately 102 mm)

R – Radial Construction

15 – Rim diameter in inches (15 inches = 381 mm)

86 – Rated Load – The rated load indicates the maximum weight each tyre may support (usually, specialized trade shops provide a load indicator table which, in this example, is equivalent to 530 kg)

V – Rated Speed – Each tyre has its own limits in terms of service speed (as for the rated load, there is a diagram or table showing the maximum speed for which the tyre was manufactured and that in this example is 240 km/h)

TUBELESS – The "tubeless" or TL reference means it is a tyre without an inner tube. When the tyre has an inner tube there is a “tubetype” or TT reference

CV90 – Design of the tyre’s grooves

The remaining information means:


1224 LBS Maximum Load Rate

Rated Pressure of 36 PSI

The casing plies are made up of six layers, of which two are rayon, two are steel and two are nylon

The sidewalls have plies with two layers of rayon
