1/50th Dayton off road heavy trailer dual tire set

This is a type of tire seen in the off road industry, such as oilfield, forestry etc. I designed this for use with a trailer for the Pacific P16 cab I offer, but it can be used elsewhere of course. The set includes 8 tires and four 'dual' Dayton type wheels. This has Dayton style fronts, planetary type rear wheels. I also offer a set of Dayton type rears for trailers to match as well. These are 52 inches in diameter, and 14 inches wide. Axles to use should be 2.5 mm in diameter. Questions? Modelmechanic@gmail.com
