I was wondering if p265/70/16 will fit on my stock 96' disco. If not what would i have to do to make them fit?

 

I think you are going to have clearance issues especially if you are running on the originial suspension that has settled and limited your tire sizes. Do you plan on 4 wheeling much, if so then I would suggest a set of coils and shocks, the new tires will fit and you'll love the difference in how your truck handles.
