Weight Distribution
Weight properly distributed to front and rear axles gives the best ride and steerability, and eliminates premature failures due to overloaded axles, springs, tires, etc.Payload distribution has a definite influence on vehicle performance. Even if the total vehicle is not loaded beyond the recommended maximum gross vehicle weight, this does not mean that individual components are not overloaded.
Overloading can be due to the improper positioning of heavy materials so that the load is centered over one rear tire or so far forward in the body that the front axle and tires are overloaded.
Unloaded or diminishing load type operations also affect the ride characteristics of a vehicle. Road vibrations and shock, for example, are not dampened in a light vehicle to the extent that they are under heavily loaded conditions.
