Welcome to the forum,
Maybe some of the forum members recently looking in the 'Wanted section' have been able to find a source
& can help with info gleaned.
Unless someone knows better, i doubt you will find 'Modular Steel Wheels' that fit,
If you just want 'Steel wheels',
There are Japanese 4x4's with the same PCD & 'centre bore' as your Freelander,
you may be able to get wheels from breakers that will suit the Freelander,
from one of these vehicles.
Possibly a Honda.
(check the various 'wheel fitment guide tables' for your vehicles PCD fitment & compare with vehicles of the same PCD)
www.alloyguide.comwww.alloyguide.com/pcd.phpYou need to be sure of the Offset/back spaceing when getting these,
to be sure they will suit the clearance in the arches & calipers you have.
Also check the stud/thread size & get the correct nuts.
Possibly call Simmonites & see if they can help with a Wheel/tyre package,
new or used.
www.simmonites.com/specials.htmPlenty of places for tyres if you can get wheels to suit from a scrap yard.
