Tire Height

Tire height is calculated as tread width X aspect ratio X 2 + rim diameter. The specific details are as follows: 1. Example: The height of a 195/60R14 tire is 195 X 60% X 2 + (14 X 25.4). Taking a tire with specifications of 185/60R14 as an example. 2. Rim diameter: 14 inches (355.6mm). 3. Sidewall height: 185 × 0.6 = 111mm. Additional information: The size and dimensions of a car tire are essentially its specifications and model, which are prominently marked on the tire. Understanding the meaning of the model and specifications on the tire is sufficient. Types of tires include: internationally standard tire codes, which represent the section width and aspect ratio percentage in millimeters. These are followed by: tire type code, rim diameter (in inches), load index (permissible load capacity code), and permissible speed code.
Speaking of tire height, I didn't really understand it when I first bought my car. Later, I learned that tire height mainly refers to the aspect ratio in the size, such as the 55 in 205/55R16, which indicates that the sidewall height is 55% of the tread width. This affects the vehicle's ground clearance and ride comfort. Tires with a high aspect ratio have thick sidewalls, good shock absorption, and are less bumpy on long trips, but they can feel a bit soft when cornering. Low aspect ratio tires have thin sidewalls, offering precise handling but a stiffer ride. Since I mostly drive in the city, I chose a medium height, which feels more balanced. Additionally, wear reduces the actual height of the tire. New tires have a tread depth of about 8 millimeters, which becomes shallower with use. I make it a habit to check the depth monthly with a coin; if it's below 1.6 millimeters, I replace them immediately to avoid slipping in the rain. Maintaining proper tire pressure is also crucial, as under- or over-inflation can affect stability. Avoid modifying the height excessively to prevent rubbing against the chassis or causing speedometer errors. In short, choosing the right tire height improves safety and driving experience, and regular checks are key.
