Reading tractor tyre markings in India involves understanding the alphanumeric codes imprinted on the sidewall of the tyre. Here's a breakdown of the common markings and what they signify:
Tyre Size: The tyre size is typically indicated as a combination of numbers and letters. For example, 13.6-28 or 6.00-16. The first number denotes the tyre's nominal section width in inches or millimeters, while the second number represents the rim diameter in inches.
Tyre Type: The tyre type is indicated by the letters "TT" (Tube Type) or "TL" (Tubeless). Tube Type tyres require an inner tube, while Tubeless tyres do not.
Load Index: The load index indicates the maximum load-carrying capacity of the tyre. It is represented by a number on the sidewall. A load index chart can be referred to determine the corresponding weight capacity.
Speed Symbol: The speed symbol denotes the maximum speed capability of the tyre. It is represented by a letter such as "A," "B," "C," etc. The corresponding speed ratings can be found in a speed symbol chart.
Ply Rating: The ply rating indicates the tyre's strength and load-carrying capacity. It is represented by a number such as "8PR" (8 Ply Rating).
Manufacturer and Model: The sidewall may also feature the manufacturer's name and the specific tyre model.
