Farmers today have more options than ever when it comes time to select ag tires. One of the most common ways to differentiate the multitude of farm tires on the market is to divide them by their construction—bias ply or radial. Both bias and radial tires have their advantages, but radials stand apart as there are no real drawbacks to their use in farming applications. Keep reading to learn more about the features and benefits of both types of tires.
1. Construction
Radial Tires:
Constructed with cords running radially (90 degrees) from the tire bead.
Multiple layers of steel belts are added beneath the tread for strength.
Bias Tires:
Built with cords laid diagonally (at angles of 30-40 degrees) in alternating layers.
No steel belts; relies on the overlapping ply layers for strength.
2. Performance
Radial Tires:
Traction: Superior traction due to better ground contact and flexibility.
Soil Compaction: Reduced soil compaction as the tire spreads the load more evenly.
Comfort: Smoother ride with better shock absorption.
Durability: Longer lifespan due to reduced heat buildup and wear.
Fuel Efficiency: Improved fuel efficiency due to lower rolling resistance.
Bias Tires:
Cost: Generally cheaper upfront.
Durability: More resistant to cuts and punctures in the sidewalls.
Stiffness: Stiffer sidewalls, making them more suitable for heavy loads at lower speeds.
3. Applications
Radial Tires:
Best for modern farming practices that require efficient fuel use, reduced soil damage, and high-speed operations.
Bias Tires:
Preferred for tasks involving rough terrains, such as forestry or operations where initial cost savings are critical.
- Drawbacks
Radial Tires: Higher upfront cost and more complex repair process.
Bias Tires: Reduced performance in terms of traction, comfort, and fuel efficiency compared to radials.
Conclusion
Radial agricultural tires generally outperform bias tires in farming applications due to their advanced design and numerous benefits. However, the choice between the two depends on specific needs, budget, and the nature of farming operations.
