GF40.10-P-1020-01A Tire designation

Component Identification:

For the designation of tires as per ECE directive, with the exception of ZR tires (see example 2), the speed symbol for the permissible maximum speed is specified after the tire size.

Component Identification:

The four-digit code or production code as per the DOT letter sequence and numerical sequence specifies the manufacture date, e.g. 0907 = 9th week in the year 2007 (number 1 and 2 production week, number 3 and 4 = the last digits of the year of manufacture).

M + S = slush and snow tires (winter tires)

All other designations are USA identification specifications.

The speed symbol "W" has been added to the usual speed symbols "Q/R/S/T/H/V/VR/ZR". This symbol identifies tires that have been approved for speeds up to a maximum speed of 270 km/h.

When installing new tires, these tires can be used as a replacement for "VR" and "ZR" tires. An entry in the registration papers is not necessary.

The speed symbol "Y" has also been added. This symbol identifies tires that have been approved for speeds up to a maximum speed of over 270 km/h.
