Cleaning

Remove the protective coating on the tires before delivery of a vehicle. This coating may cause deterioration of the tires.
To remove the protective coating, apply warm water and let it soak for a few minutes. Afterwards, scrub the coating away with a soft bristle brush. Steam cleaning may also be used to remove the coating.

NOTE: DO NOT use gasoline, mineral oil, oil-based solvent or a wire brush for cleaning.
