Tire Load And Inflation Tables - MASSEY FERGUSON 410 Operators Instruction Book

Tire load and inflation tables

The correct inflation pressure (Table 18) is the most
important factor contributing to satisfactory
performance of agricultural tires. Correct inflation
pressure can be determined by weighing the loaded
axle (for example, the rear axle with the implement
in the raised position) and then referring to the load
and inflation tables for the relevant tires. Tire loads
should be calculated to include full bins and tanks
as well as weights and ballast. One should only
increase recommended inflation pressures of
agricultural tires for reduced speed/higher load
applications, hillside plowing and operation on hard
surfaces for any length of time - such as road
transport. Tire load carrying capacities vary with
speed - increased loads often apply at lower speeds,
and reduced loads at higher speeds than those
indicated in the following tables. The load capacity
in the tables is given in kilograms (lb) at a speed not
exceeding 30 km/hr (20 mph).
Rear radial drive tires.
Load capacity kg (lb) - inflation bar (psi) at 30km/hr (20 mph).

Determining the weight
With the implement mounted on the 3-point hitch
drive the tractor onto a weighbridge so that the rear
wheels only are on the platform. Take the weight
reading and divide by two, compare the weight and
tire size with the table below to determine the tire
pressure. For example:
Tractor on 13.6R28 tires weighing 2160 kg (4762 lb)
divided by 2 = 1080 kg (2381 lb) per wheel. 1070 kg
(2359 lb) is the nearest reading, tire pressure is 0,6
bar (9 psi).
