              Any idea of the size needed ? How do the sizes of rim locks equate to the size of the rim ?

         The front wheel is 1.85 and the rear 2.75 - I've only ever got these direct from the dealer, so I can't be 100%, but I can't imagine for the life of me why the lock sizes would be different from the wheel/tire sizes.
         
        
 If you're off overland, then yes you are wise to fit these, especially if you match it up with good off road rubber, you'll get away with running a flat for a long way.
