I've got 30k miles on a set of 285-75/17s on my 1st Gen and they do not appear to be near half gone yet. Very quiet and highest load rating in it's class, if you tow. That size equals about a 34" tall tire so will give a nice jump in overall gearing above stock for a bit better highway fuel mileage.
