Calculation of freight car tire consumption
In addition different brands vary greatly, the domestic three packs of semi-trailer axle wheel drive in picking only 6-8 million kilometers, Bridgestone can reach more than 250 thousand kilometers (drive shaft special M729), Michelin is said to have a can reach more than 400 thousand kilometers, not a lot of data support there is no way to do this calculation.
For example, the same is pulling coal cars, because of the difference between the place of unloading have forklift, driving shaft tire life was doubled (the same brand), because the coal unloading after pulling coal cars drive shaft tire is no cinder coverage, forklift will lead to start the tire and cinder friction substantially reduced life expectancy, and push on the forklift tire life is greatly prolonged.
Different brands, different patterns, different specifications of the tires in different road conditions, different models, different axle positions, different loads, different pressure, different seasons, life varies greatly.
