AL-KO 10 hub drum 6 x 139.7mm PCD (6 stud Landcruiser) with 1/2 UNF studs.
What a stupid system.
Nothing on a Landcruiser is imperial. It is metric.
If I owned a Landcruiser tug, I would want the rims, tyres, studs and nuts to all be metric and identical to the Landcruiser so that everything was interchangeable.
