for a daily drive dont go with more than a 30 inch tire on this vehicle. also these are well known for ball joint problems so a bigger tire will only make things worse. if you have oversize tire and a factory warranty still in effect they will deny your claim if it needs ball joints also. its out of warranty more than likely though. as far as lift does he plan on much offroading or not? if not go with a body lift so it wont screw with the geometery of the suspension. also if my memory is correct the stock metric tire is a 30 inch tire.
just my .02
