Proper wheel selection for commercial mowers impacts:
| Size | Diameter | Width | Max Load |
|---|---|---|---|
| 11x4.00-5 | 11" | 4" | 600 lbs |
| 13x5.00-6 | 13" | 5" | 850 lbs |
| 15x6.00-6 | 15" | 6" | 1200 lbs |
Ground Pressure = (Weight × Terrain Factor) / (Contact Area × 144)
Contact Area = π × (Width/2) × (Diameter × Aspect Ratio)
