The specification that denotes the appropriate dimensions and load-bearing capacity of a vehicle’s wheel and tire assembly, specifically tailored for a mid-size sedan manufactured by Toyota. This specification includes elements such as tire width, aspect ratio, wheel diameter, load index, and speed rating, all crucial for ensuring safe and optimal performance. For example, a marking of “215/60R17” indicates a tire width of 215 millimeters, an aspect ratio of 60%, radial construction, and a 17-inch wheel diameter.
Adhering to the recommended wheel and tire specification offers several key advantages. It maintains the vehicle’s intended handling characteristics, ensures accurate speedometer readings, and prevents undue stress on suspension components. Furthermore, utilizing the correct specification contributes to optimal fuel efficiency and maximizes tire lifespan. Historically, automobile manufacturers have invested significant resources in determining the optimal wheel and tire parameters for each vehicle model, ensuring a balance between performance, safety, and comfort.
