Tire Replacement

Yokohamas are designed to last, but even the best tires wear out over time and miles. It’s important to inspect your tires monthly to ensure proper performance.

Tires must be replaced when the depth of the tread reaches 2/32” (1.6 mm). Yokohama tires are manufactured with tread wear indicators molded into the tire grooves which indicate tread wear out. As tires wear down to 2/32” (1.6mm), and tread depth is reduced, tire traction is reduced during rainfall and winter road conditions. While the minimum allowable tread depth is 2/32”, tires may lose sufficient wet and snow traction before reaching 2/32” (1.6 mm). The vehicle owner must determine if tires should be replaced prior to reaching 2/32” tread depth based on the conditions under which the vehicle is operating. A visual tire inspection, therefore, becomes more crucial as the tires wear out.

You also can insert a penny into the tire tread with Lincoln’s head upside down. If you can see all of Abe’s head, the tread is too worn and the tire ready to be replaced.

Yokohama recommends tire replacement in full sets of the same size, tread design, construction, load index and speed rating. When the vehicle manufacturer guidelines for tire replacement differ from those of Yokohama, the owner should follow the vehicle manufacturer’s recommendations for tire replacement.

If the vehicle placard specifies different sizes on front and rear axles, replacement tires should be an exact replacement, including both representative load index and speed ratings. If size has been changed from the vehicle's original size, tire pressure recalculation may be necessary. Yokohama’s Consumer Affairs department is available to help with tire pressure recalculation at 800-722-9888.

If the decision is made to only apply two new tires, the new tires should be installed on the rear position, as explained in the accompanying video:


To maintain vehicle dynamics and load carrying capacity, replacement tires must always have a load index and speed rating that equals or exceeds that of the original equipment tires of the vehicle. Driving your vehicle with an improper mix of tire sizes, constructions and speed ratings can be dangerous. Your vehicle’s handling characteristics can be adversely affected. Before replacing tires, always consult and follow the vehicle owner’s manual or an authorized Yokohama dealer for proper tire replacement.

Tire changing can be dangerous and should be done using proper tools and procedures. Always use approved tire/rim combinations for rim diameter, width and contour. Always replace a tire on a rim with another tire of exactly the same rim diameter designation.

When changing between P-metric, Euro-metric, LT-metric and flotation sizes, both inflation pressure and load carrying capacity adjustments may be required. Consult your tire service professional.

Road Hazards

Objects on the road that could damage your tires should be safely avoided. These objects include: potholes, glass, metal, rocks, wood debris, curbs and the like. Damage from impact can occur to the inner portions of your tire without being visible to the outside and can result in tire failure. If you suspect a tire has been damaged, immediately replace it with a properly inflated spare tire, and have the damaged tire removed from the rim and inspected both inside and out by a qualified tire technician.
