| Pressure too high | Pressure too low |
| Excessive soil compaction | Risk for tire casing durability |
| Extensive rut formation | Rotation on wheel rim |
| Excessive spin (overconsumption) | Irregular wear on roads |
| Fast, irregular wear on roads | Overconsumption on roads |
| High risk of tearing tread blocks | Vehicle instability |
| Uncomfortable ride |
The right pressure means an optimum soil contact and therefore a larger footprint which causes spin and penetration to be reduced. To calculate the right pressure there’re four criteria’s:
- The sizes of tires and their characteristics (load and speed index)
- The maximum speed at which you use your machines
- The total weight supported by your tires – machine weight+ weight of tools+ load transfer
- Operating use: cyclical or non-cyclical.
Use this formula to calculate tire pressure
A = B * (C / D) ^ 1.25
A= the tire pressure you want to know B= the maximum tire pressure, which you can find on the tire C= The actual weight on the tire D= the maximum load for the tire also can be found on the tire in lbs, kg, or load-index
