The dimensions of the rubber that makes contact with the road on a 2004 Toyota Corolla are a crucial specification for vehicle performance and safety. This measurement, typically expressed in a format such as 195/65R15, indicates the tire’s width, aspect ratio, construction type, and rim diameter. Understanding these values ensures compatibility and optimal handling.
Correctly specified tires are essential for maintaining the vehicle’s intended handling characteristics, braking efficiency, and fuel economy. Using the originally designed parameters contributes to the longevity of suspension components and accurate speedometer readings. Furthermore, adhering to these guidelines ensures that the vehicle operates within its designed safety margins, reducing the risk of accidents caused by improper tire selection. Historical data and owner’s manuals serve as key resources for verifying appropriate dimensions.
