Fri, 16 Aug 2024 | PRODUCTS
Selecting the right tractor tyre is crucial for optimising performance and ensuring safety in agricultural operations. One of the most common challenges for farmers and equipment managers is deciphering the information printed on tyre sidewalls. This blog will clarify the tyre information for the 520/85 R 42 FARMAX R85 169D/172A8 TL, helping you make informed decisions for your agricultural needs.
Breaking Down the Tyre Specification
When examining a tractor tyre like the 520/85 R 42 FARMAX R85 169D/172A8 TL, it's essential to understand the meaning behind each component of the designation. Here’s a detailed breakdown:
1. 520/85
520: This number represents the tyre’s width in millimetres. In this case, the tyre is 520 millimetres wide. Tyre width impacts traction and stability, making it a critical factor for different types of terrain and load requirements.
85: This number indicates the aspect ratio of the tyre’s height to width. Specifically, it’s a percentage, meaning the sidewall height is 85% of the tyre’s width. A higher aspect ratio typically produces a taller sidewall, providing a smoother ride and better shock absorption.
2. R
R stands for Radial construction, the most common type of tyre construction for modern agricultural tyres. Radial tyres have fabric plies that run perpendicular to the direction of travel, providing better flexibility, improved traction, and greater comfort than bias-ply tyres.
3. 42
42 refers to the diameter of the tyre’s rim in inches. In this instance, the tyre fits a 42-inch rim. The rim diameter affects the tyre’s overall size and performance characteristics, including load capacity and ride quality.
4. FARMAX R85
FARMAX R85 indicates the CEAT Specialty tractor tyre series and its intended use. The FARMAX series is designed for high durability and performance in agricultural settings, while the R85 is tailored for optimal load-bearing and traction.
5. 169D/172A8
169D/172A8 refers to the tyre’s load index and speed symbol:
169D: The load index (169) represents the tyre's maximum load capacity when properly inflated. In this case, 169 corresponds to a load capacity of approximately 3,600 kilograms per tyre. The speed symbol (D) denotes the maximum speed rating, with D indicating a maximum speed of 65 km/h.
172A8: This indicates an alternative load index and speed rating, providing additional information on load capacity and speed, which may vary slightly from the primary specification.
6. TL
TL stands for Tubeless, meaning the tyre is designed to operate without an inner tube. Tubeless tyres offer advantages such as reduced risk of punctures and lower rolling resistance, leading to improved fuel efficiency and performance.
Why Accurate Farm Tractor Tyre Information Matters?
Understanding the farm tractor tyre specifications is essential for several reasons:
- Performance Optimization: Selecting the correct tyre size and type ensures optimal traction, stability, and comfort performance. Mismatched tyres can affect your tractor's efficiency and safety.
- Load Capacity: Knowing the load index helps you choose a tyre that can handle the weight of your equipment and the loads you are transporting. Overloading a tyre can lead to premature wear or failure.
- Speed and Safety: The speed rating ensures that the tyre can safely handle the speeds at which your tractor operates. It’s crucial for both performance and safety.
- Compatibility: Ensuring the tyre fits the correct rim size and construction type (radial or bias) guarantees proper installation and performance.
