The specified vehicle model from that production year typically utilizes a particular wheel and pneumatic component dimension. This measurement ensures correct fitment within the wheel wells and compatibility with the vehicle’s suspension and braking systems. The information is usually presented in a format consisting of numbers and letters, indicating width, aspect ratio, and rim diameter.
Selecting the appropriate dimension is critical for maintaining optimal handling characteristics, fuel efficiency, and speedometer accuracy. Deviation from the recommended parameters may negatively impact performance, safety, and even tire wear. Vehicle manufacturers extensively test to determine these specifications to provide the best balance of ride quality and performance. Adhering to the original equipment manufacturer’s recommendation generally ensures the intended driving experience.
