The specified numeric and alphanumeric code indicates the appropriate dimensions and specifications for the tires designed to fit a particular vehicle model and year. For the 2005 Toyota Highlander, understanding this code is crucial for ensuring proper fit, performance, and safety. The size typically includes aspects such as width, aspect ratio, and rim diameter. For example, a common specification might be 225/70R16, where 225 represents the width in millimeters, 70 is the aspect ratio (sidewall height as a percentage of the width), R signifies radial construction, and 16 denotes the rim diameter in inches.
Selecting the correct specification is paramount for maintaining the vehicle’s handling characteristics, speedometer accuracy, and overall safety. Using an incorrect size can lead to inaccurate speed readings, compromised braking performance, and potential damage to the vehicle’s suspension or drivetrain. Furthermore, adhering to the manufacturer’s recommended dimensions helps ensure optimal fuel efficiency and tire wear. Historically, vehicle manufacturers have carefully determined these dimensions through extensive testing to provide the best balance of performance, comfort, and safety for the vehicle in question.
