Except as provided in subsections (4) and (5) of this section or where an exemption under ORS 818.030 specifically provides otherwise, a loaded weight that exceeds the maximum allowable weight as determined by any of the following tables exceeds the maximum weight limitations for purposes of ORS 818.020:\n      (1) A vehicle exceeds the maximum allowable weight if the loaded weight of an axle or tandem axle is in excess of that determined by the formula in the following table:\nTable I\n      The manufacturer’s side wall tire rating (but not to exceed 600 pounds) ´ the sum of the tire widths, in inches, of the wheels of the axle or tandem axles = maximum allowable weight.\nFor purposes of the table in this subsection tire width is determined by measuring the cross section of the tread of a wheel, the outer face of a track or the runner of a sled except for the following:\n      (a) For solid tires made of elastic material, tire width is determined by measuring the cross section between the flanges of the circumference of a wheel at the base of the tire as customarily measured and rated by the manufacturers of motor vehicles and tires.\n      (b) For pneumatic tires made of elastic material, tire width is the diameter of the cross section of the tire as customarily measured and rated by the manufacturers of motor vehicles and tires.\n      (2) A vehicle or combination of vehicles exceeds the maximum allowable weight if the loaded weight measured at any of the places designated on the following table exceeds the maximum allowable weight established on the table for measurement at that place:\nTable II\nPlace for measurement                     Maximum allowable\nof weight                                           weight in pounds\n      Any

combination of vehicles exceeds the maximum allowable weight if the loaded weight is in excess of maximum allowable weight as determined by the method in the following table that produces the lower allowable maximum weight:\nTable III\n(Maximum allowable weight\ndetermined by whichever of the\nfollowing methods produces lower weight:)\nMethod A\n      The sum of permissible axle, tandem axles or
