WEIGHT
818.010Maximum allowable weight. This section establishes maximum weight limitationsfor purposes of ORS 818.020. Except as provided in subsections (4) and (5) ofthis section or where an exemption under ORS 818.030 specifically providesotherwise, a loaded weight that exceeds the maximum allowable weight asdetermined by any of the following tables exceeds the maximum weight limitationsfor purposes of ORS 818.020:
(1)A vehicle exceeds the maximum allowable weight if the loaded weight of an axleor tandem axle is in excess of that determined by the formula in the followingtable:
______________________________________________________________________________
Table I
Themanufacturer’s side wall tire rating (but not to exceed 600 pounds) ´the sum of the tire widths, ininches, of the wheels of the axle or tandem axles = maximum allowable weight.
______________________________________________________________________________
Forpurposes of the table in this subsection tire width is determined by measuringthe cross section of the tread of a wheel, the outer face of a track or therunner of a sled except for the following:
(a)For solid tires made of elastic material, tire width is determined by measuringthe cross section between the flanges of the circumference of a wheel at thebase of the tire as customarily measured and rated by the manufacturers ofmotor vehicles and tires.
(b)For pneumatic tires made of elastic material, tire width is the diameter of thecross section of the tire as customarily measured and rated by themanufacturers of motor vehicles and tires.
(2)A vehicle or combination of vehicles exceeds the maximum allowable weight ifthe loaded weight measured at any of the places designated on the followingtable exceeds the maximum allowable weight established on the table formeasurement at that place:
______________________________________________________________________________

ofweight weight in pounds
Anyindividual wheel 10,000
Anyaxle 20,000
Anytandem axles 34,000

(3)A vehicle, group of axles or combination of vehicles exceeds the maximumallowable weight if the loaded weight is in excess of maximum allowable weightas determined by the method in the following table that produces the lowerallowable maximum weight:
