Mounting Procedures

Use of Bead Lubricant

Preferred materials for use as bead lubricants are animal- or plant-based and mixed with proper water ratios per manufacturer's instructions. When dry, the lubricant should have no residual lubricity and should not flake from the surface upon which it is applied. To avoid damage to tires and rims, the following should be avoided: petroleum oils or grease, improper ratios of approved lubricants and water, silicone oils and emulsions, and solvent-based lubricants.


Use of Sealants

Yokohama does not recommend, endorse, or prohibit additives installed in the interior chamber of its mounted tires, provided the material is not flammable and or injurious to the tire chamber or structure and does not replace air pressure as the tire’s primary inflation medium. The Yokohama Standard Limited Warranty remains in effect with the use of these additives, providing the additive is not the cause of a tire condition submitted for a warranty claim. Damages attributed to the use of an additive will be denied warranty consideration.


Mounting Directional Tires

When mounted properly, directional treads prevent block squirm, effectively reducing irregular wear and improving tread life.


Direction of Rotation

When viewed from the top, the tread pattern should face in the following direction:


Directional treads should be mounted facing opposite directions to ensure their “direction of rotation” arrows are each pointed to the front of the vehicle. This arrow can be found on the sidewall.
