swapping to mud tyres - what's the largest size?

[RIchie]

I am keen to add some lift to my 2019 Navara.  It has the flared arch kits, so I am hoping someone will know whether I can go up to 225/85/R16 mud tyres, or whether I need to stop at the 75's?

I am happy to go for the lift kit as well, if it makes a difference.

It currently has the black gloss alloys, so would rather keep these if poss, unless someone knows of a set of muddies going already on alloys

What's your experiences of fitting larger wheels/tyres please?  What other car wheels fit the Navara pls?

Thanks for your help
