Knowledge of trucks: what is axle load

 The weight of the front and rear bearings, said the general axle load ratio is the ratio of the front and rear axle share the weight of the car, for the car, the front and rear axle load ratio 50:50 best. This ratio of axle load distribution is conducive to the uniform wear of tires, to ensure that the car has better cornering characteristics and driving stability. 

Front-and rear-wheel-drive (FR) models are easier to achieve 50:50 axle load distribution because the engine and drive are located in the front and rear of the vehicle respectively. Front-wheel drive (FF) of the car, the best front axle load of 55% or more to ensure that there is enough driving force uphill. The rear axle of a 4x2 truck with twin tires has six tires and the front and rear axle loads should be 1/3 and 2/3 of the total mass respectively.
