This Architectural Drawing is AutoCAD 2d drawing of Four and six tire truck detail in AutoCAD, dwg file. With four back wheels instead of two, and a stronger rear axle, a dually truck can handle a larger amount of payload weight and offer more towing capacity compared to its standard single rear-wheel (SRW) pickup truck counterparts. Also the tyres are broader because this increases the area of contact with the ground, thus reducing the pressure exerted on the ground. For more details and information download the drawing file.
