Passenger tires in the United States are available in two size designations: ‘P-Metric’ and ‘European Metric’. The difference is easily identifiable in that P-Metric sizes begin with the letter ‘P’ whereas European Metric sizes have no alpha designation. This bulletin gives guidance on replacing P-Metric OE fitments with European Metric tires of the same nominal size (section width, aspect ratio, and rim diameter).

Yokohama ZPS (Zero Pressure System) runflat tires include special technology to allow the tire to operate at reduced speeds and distances with zero inflation pressure.

To help customers understand appropriate care for their tires and important considerations for tire replacement, Yokohama has prepared these guidelines.

Yokohama Tire Warranty Policy as it pertains to tire rotation and mileage warranty.

The purpose of tire registration is to enable the tire manufacturer to contact you directly in the event of a recall. While a recall is unlikely, it's important to make sure your tires are properly registered.

The storage of tires requires particular care. If tires are not stored properly, not only will there be deterioration in their appearance, there may be a loss in performance and compound integrity.
