Understanding Tire Size: A Guide for Drivers

The other day, while enjoying a coffee at my usual spot, I ran into Mr. Ba, a seasoned truck driver known for his Hanoi-Hai Phong route. Hearing me complain about a recent tire change, he chuckled, “My friend, choosing tires is a serious matter. Knowing how to read tire size is the first step to a smooth journey!” His words struck a chord, as I realized I wasn’t entirely clear on the numerous markings on a tire. Thanks to Mr. Ba’s patient guidance, I’m here to share the “secret” of understanding tire size.

Decoding Tire Size Markings

Tire size is usually represented by a sequence of numbers and letters, for example: 195/65R15 91H. It might seem complex, but it’s quite simple. Let’s break down each component:

1. Tire Width (195):

The first number, typically three digits, indicates the tire’s width in millimeters (mm). In this example, the tire width is 195mm.

2. Aspect Ratio (65):

The next number, usually two digits, represents the percentage ratio between the tire’s sidewall height and its width. In this example, the ratio is 65, meaning the sidewall height is 65% of the tire width.

3. Tire Construction Type (R):

The letter “R” in this example indicates a Radial tire construction – the most common type used for most cars and light trucks.

4. Wheel Diameter (15):

The following number indicates the diameter of the wheel rim in inches. In this example, the wheel diameter is 15 inches.

5. Load Index (91):

This number indicates the maximum weight a tire can carry. Each load index corresponds to a specific weight capacity. For instance, the index 91 corresponds to a load of 615kg (1356 lbs).

6. Speed Rating (H):

The final letter indicates the maximum speed a tire is rated for. For example, the “H” rating corresponds to a maximum speed of 210km/h (130 mph).
