These are my brothers rims, they are a size 16 and has the TrXuS on them now, and he is going to give them to me, but I want new tires

What is the largest tire that will fit on a lifted KJ that is 2.5 inch lift, soon to be a 3 or 4 inch lift

So what size tire should I get?

Also, are the Kumho Road Venture MT good tires for a KJ?
