Yokohama Y870B Tires

Product Info

Y870B

If you need an exact replacement for a factory spare, Yokohama Y870B tires are built for temporary mobility in a narrow set of passenger-car fitments. Tire Crew can help you match the correct sidewall size before you order, which is especially important for OE-style spare applications.

This model is cataloged in three sizes: 135/70-18, 145/90-16, and 155/90-17. Each listed fitment carries an SL load range, an M speed rating, and 60 psi maximum inflation, so it is designed around temporary spare use rather than everyday driving.

Because the Y870B is a compact spare tire, size confirmation matters more than tread features. There is no mileage warranty listed in the active catalog, and the model is not shown as LT, run-flat, snow-rated, or flotation. For help confirming the right replacement, browse Yokohama tires, check Tire Warranty Information, or schedule service through Tire Crew.
