The specific dimensions of the rubber and wheel assembly for a 2014 Toyota Highlander are crucial for maintaining vehicle performance and safety. These dimensions dictate the physical characteristics of the tire, including its width, aspect ratio, and wheel diameter, and are typically expressed in a standardized alphanumeric format. As an example, a common specification for this vehicle is P245/60R18, where ‘P’ indicates a passenger vehicle tire, ‘245’ represents the tire width in millimeters, ’60’ is the aspect ratio (the height of the tire sidewall as a percentage of its width), ‘R’ signifies radial construction, and ’18’ denotes the wheel diameter in inches.
Correct tire sizing is paramount for several reasons. It directly influences the vehicle’s handling, braking distance, and fuel efficiency. Employing the manufacturer-recommended specifications ensures that the vehicle’s safety systems, such as ABS and traction control, operate as intended. Furthermore, using the appropriate size maintains speedometer accuracy and prevents potential mechanical issues arising from improperly fitted tires. Historically, consistent tire sizing has aided in streamlined production, standardized replacement, and enhanced overall vehicle reliability within specific models.
