JWL standard


The JWL standard (Japan Light Alloy Wheel standard) is a set of requirements for alloy wheels set by the Ministry of Land, Infrastructure, Transport and Tourism (Japan) that must be met for all passenger cars in Japan. The JWL mark, cast or forged into the wheel, indicates that the wheel has been self-certified by its manufacturer to meet the standard. There is a related standard, JWL-T, for truck and bus wheels.

The Vehicle Inspection Association of Japan (VIA) independently tests wheels for JWL or JWL-T compliance. Wheels that have been tested will bear the VIA mark in addition to the JWL mark.
