Contact your Komatsu distributor when replacing the tires. It is
dangerous to jack up the machine without taking due care.
T.Km.P.H (Ton-Km-Hour-Rating)
A tire for the construction machinery has a structure which can tolerate the severe condition, that is incompara-
bly more severe than that of automobiles, buses, general trucks.
Heat is more generated inside the rubber material in OR tires comparing to the general tires during traveling.
The temperature inside the rubber material exceeds the allowable limit if they are used continuously with more
load than their load limit and at higher speed than their speed limit. It may cause the heat separation due to
softening of the rubber.
T.Km.P.H is provided as the standard for the safety travel of the machine in order not to make an incident occur
which is described above.
More tire trouble will occur if the work demanding more T.Km.P.H to the tire is performed (the work T.Km.P.H
value exceeds the T.Km.P.H value particular to the tire).
Observe the following in such case.
• Moderate the work condition so that the work T.Km.P.H value goes down.
• Change the tire to the one whose T.Km.P.H value is higher.
TIRE T.Km.P.H VALUE AND CONTINUOUS MAX TRAVEL SPEED
How to obtain the work T.Km.P.H value by calculation
The work T.Km.P.H value = Average load per tire x Average travel speed of a day
Average travel speed = The distance of round trip x How many times the round trip is made in a day/Total oper-
ating hours in a day
Average load = (load when un load when loaded)/2
Total operating hours in a day includes the break time and downtime.
*The T.Km.P.H value in the table varies depending on the manufacturers of tire. Ask your Komatsu distributor
when the work is to be performed with the travel speed near the travel speed shown in the table.
