Selection of the Vehicle Operation Cost Model

• Easy to use
• Availability of appropriate input data
• Applicability of the model in various European
  scenarios
• Ability to deal adequately with the question of
  different tyre types

Chosen VOC model of a truck manufacturer (MB)

Calculation of Vehicle Operation Costs

• Germany
• Wide base single tyres vs. twin tyres on drive
  axle
• New tyres and regrooved and retreaded tyres
• Articulated (current) 40t vehicle and (old) 38t
  vehicle

• United Kingdom
• Articulated 5 axle 40t vehicle
• Old case with 11R22,5 tyres, twins on the
  semi-trailer
• Recent case with 295/80R22,5 tyres, twins on the
  semi-trailer
• Current (base) case with wide singles on the
  semi-trailer
• New case with wide singles on drive axle and
  semi-trailer

Max. benefit due to additional payload from
lighter wheel weights

• Assumptions for the 40t tractor semi-trailer
• Truck operation 150.000 km per year
• Load capacity 26t, utility rate 0,6 average
  load capacity 15,6t
• Less tyre and rim weight. 130-150 kg 1 of
  aver. load capacity
• Max. Gain 1 of annual truck operation cost
  (135.000 )
• 1.300

Only to be achieved if additional freight is
available and enough empty space in the
semi-trailer
