Stock rims are 5.5 inches wide, the heavy duty rims fitted to your 110 will be 6 inches and the minimum recommended wheel width for fitting to 235 section tyres (eg 235/85/16 BFG MT's) is 6.5 inches.
Discovery steel wheels are 7 inch and perfect for off road use - I picked up a set in the UK for about £30 off ebay. Best to avoid expensive alloys if you're using it off road, you can beat the dents out of a steel wheel with a club hammer, not so with an alloy.
Ebay is your friend for inexpensive steel wheels - here's what they look like fitted with 235/85 Insa Turbo Sahara remoulds on my 90.
Cheers,
wheels
