Hello Andy,
now you have a blank canvas you might think about getting a lift on the 110,
then you can fit what ever tyre size you want....within reason.
255's should be no problem with a standard set up and you'll probably get awya with not having to alter the end stops on the steering.
A lift will mean you can fit bigger tyres and get that diff a bit higher off the ground if you play in the sticky stuff or do greenlaning.
Cheers for now,
