With thanks to Alvaro Rodriguez, this set is exquisitely 3D CAD designed to accurately represent authentic Dunlop tyres for the standard Medium Artillery mounting. The same type was used for the BL 4.5-inch gun
The tread pattern is what sets Alvaro's designs apart. This set is made for the Airfix kit in 1/76 though they could be used on a 1/72 scale scratchbuilt model.
