- Radial tires operate at lower pressure
- Radials offer a flat, stable and wider footprint
- Radials offer a better ground pressure distribution
|
|
- Bias tires require more pressure to carry a given load as compared to the same size radial
- The casing stiffness factor of Bias tires translates into greater soil contact pressure.
|
Compared to Bias, Radial Tires reduce soil compaction and offer better traction. |
|
2. Wider low Profile tires are better than Standard tires
To reduce pressure at constant load, you should increase tire volume.
How to increase tire volume and decrease pressure?
- Increase tire section width and keep diameter & loaded radius equal
- Increase tire diameter while maintaining width & rim diameter equal
- Use duals/ triples.
