Understanding tyre size meaning
Let’s use this tyre code - 195/65 R15 91H to understand its various elements:
Tyre width (195): The first three-digit number represents the tyre’s width measured in millimetres. The example tyre shown above has a width of 195mm.
Aspect ratio (65): The two numbers following the tyre width is the aspect ratio, measured by the height of the tyre’s cross-section divided by its width. In the given example, the sidewall height would be 65% of its width.
Tyre Construction (R): This informs how a tyre is constructed, and it can either be ‘R’ or ‘D’. In the example, R stands for radial construction, where internal ply cords run in a radial direction across the casing.
Rim diameter in inches (15): The next two numbers represent the wheel’s diameter measured in inches. In the shown example, number ‘15’ refers that the tyre size should match a wheel of 15 inches.
Load index (91): This number indicates the maximum load that a tyre can support when properly inflated. The higher the number, the greater the load-bearing capacity of tyres Ponteland. For a load index of 91, the maximum weight that can be safely carried is 615 Kg.
Speed rating (H): The final marking refers to the maximum speed at which a tyre can operate safely when the load and tyre pressure are within correct levels. In this example, H refers to a maximum speed limit of 210 kmph (130 mph).
