Rice farmer Hunt horse trailer- rear load

[Bruna Smith]

I have purchased a second hand Rice farmers hunt horse trailer and it's one with a rear load and I was wondering what kind of security locks are available for this old school trailer.
The tyres are massive- Range Rover ones. None of the wheel locks seem to fit. Diameter of 28 inches.
Can I use a standard hitch lock for it?
Where could I purchase it from?
Thank you

A bulldog wheel clamp should fit as they are adjustable so can go round most tires I would have thought.

I have a farmers hunt. They come with 15" diameter wheels on. Another 15" on top of that seems excessive; in fact I doubt they would fit underneath the mud guards?

Anyway I did a search on ebay and purchased one from there.
