The 185/60R21 is a relatively uncommon tire size found on select compact and subcompact vehicles, most notably certain trims of the Toyota Prius and other fuel-efficient hybrid models that use narrow, tall tires to reduce rolling resistance. This size is specifically engineered for vehicles where aerodynamics and fuel economy are prioritized over performance handling. Buyers should verify their exact trim level, as similar Prius models may use different tire sizes depending on the model year.
At the budget end, Kumho and Nexen offer reliable options in this size that deliver solid everyday performance at accessible price points. Mid-range shoppers should consider Toyo or Falken, which provide a good balance of longevity, fuel efficiency, and ride comfort well-suited to hybrid vehicles. For premium performance and maximum fuel efficiency ratings, Michelin and Bridgestone are the top choices, with models specifically designed to complement the low rolling resistance requirements of hybrid drivetrains.
Treddur is currently tracking 10 listings for 185/60R21 tires. Prices range from $65.96 to $162.08 depending on brand and retailer.
Because this size serves primarily fuel-efficient commuter vehicles rather than performance or off-road applications, all-season tires dominate the market and are appropriate for most buyers year-round. Shoppers in snow-prone regions should consider purchasing winter tires in September or October before seasonal demand drives up prices and reduces availability in this already limited size.
Due to the limited number of tire models manufactured in the 185/60R21 size, prices tend to remain relatively stable with less discounting than more common sizes, and significant sale pricing is rare outside of major retail events.
