I want to lift the 3/4 ton crew cab - I am looking for the max tire size you can run with a 4 inch AND a 6 inch - I haven't decided which one I want yet but I am leaning towards a 4 inch. Also can you please break it down in old school tire size along with the new metric crap that we have adopted I miss being to understand 14x35x15 .. I just don't get the P 265 blah blah blah.. I currently have 16 inch rims/wheels but I am sure they are out of size style for most tires today.. I would like to run a 35 inch tire on a 4 inch lift if I could.? Thanks in advance..
