12. OPERATION If the deflection of the tire is excessive, raise the inflation pressure within the limits given in the table to give a suitable deflection (see deflection ratio). Tire size (pattern) When shipped from factory Front tire: 0.67 MPa 45/65-45 (6.8 kgf/cm 2 , (Standard) Rear tire: 0.67 MPa (6.8 kgf/cm 2 , (L5 Rock) 96.56 PSI) 96.56 PSI) Stockpile operations mean the loading of sand and other loose materials. PRECAUTIONS WITH LOAD AND CARRY METHOD When traveling continuously with load and carry operations, choose the correct tires to match the operating conditions, or choose the operating conditions to match the tires.
If this is not done, the tires will be damaged, so contact your Komatsu distributor or tire dealer when selecting tires. 2-72 Ply rating H Free height (mm) Soft ground (sandy ground) Normal road Stockpile Digging Stockpile Digging 58 679 0.62 – 0.67 MPa (6.3 – 6.8 kgf/cm2, 89.46 – 96.56 PSI) 0.62 – 0.67 MPa (6.3 – 6.8 kgf/cm2, 89.46 – 96.56 PSI) 0.62 – 0.67 MPa (6.3 – 6.8 kgf/cm2, 89.46 – 96.56 PSI) 0.62 – 0.67 MPa (6.3 – 6.8 kgf/cm2, 89.46 – 96.56 PSI)
