ZU wheels and tyres to fit Tdci

I am looking to buy 16x7 ZU alloys for my 2007 tdci defender 90 (are these the widest wheels i can fit without mods?) does anyone know what widest tyres such as a bfg mud terrain or maxxis mudzilla I can fit to these rims without making any modifications?

i am new to the world of landy's and lots of help is needed!

dunno if its the same on your newer defender but on mine the largest i can fit is 265/75/16 with no mods

seriously mate this is the most asked qs that people dont bother to search before asking it
