UTQG Ratings

Universal Tire Quality Guide (U.T.Q.G)

The UTQG is measured with three specific criterias, stating the classification of a tire. The data are collected after on a closed circuit.

Tread wear

The first crtieria found on a UTQG  is the life expectency of a tire, how fast is it going to wear. This number is ontained by a test on a circuit of  9600 kilometers, in controlled conditions. 100 is the reference value, so if a tire has a tread wear of 50, it will wear twice as fast as the refenrence tire, whereas a tread wear of 600 means that the tire will last six times more. The higher the number, the longer the life of a tire.


The traction indicator represents how a tire will perform on wet surfaces. It is determined by the letters AA (best indicator), A, B and C (lowest score possible). The higher the letters, the more performance you get from the tire.


The temperature index defines how resistant a tire can support and dispel heat. This index is the result of tests in laboratory as well as road tests.

An over heating tire can provoke the degradation of a tire in an irregular way. The index is rated by the letters A (best index) B and C (minimum required by the law). The higher the letter, the better the heat dispel.

N.B. UTQG is a useful tool to compare tires from A SAME BRAND. We cannot compare the UTQG of a Michelin tire with a Bridgestone one.
