WARNING: This page is about a different car, the 2022 Volkswagen ID.4 and 2021 Volkswagen ID.4. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:

Only Volkswagen Original + tires have been introduced for the launch of the ID.3 and all following electric vehicles as well as successively for all gasoline vehicles. They have been specially destined with our previous tire manufacturer for our Volkswagen models and go through over 50 test requirements. Result: tires which match the specific properties of the vehicle model and in this way put all the power to the road. Volkswagen original + tires can be identified by the plus as a new OE marking on the side surface on the tires.
