off a newer frontier onto a 2002 xe?

No wrong bolt pattern.

Though they are six lug they are on tighter lug circle and therefore will not mount.

so what model vehicle should i be looking for some used wheels and tires? chevy tahoe? if i remeber right the lug pattern is 6x5.5? and also what is the maximum tire size i can fit without trimming plastic or lifting it? thanks for the help

All your questions should be answered in already existing threads. Search official tire size or something along the lines of that to see what others are running. The search tool is your friend,
That's how I have found out most everything I know.

and yes the bolt pattern is 6x5.5

Is that Spam or What???

The maximum tire size will be 32x11.50 or 265/75 and some tahoe wheels would fit but newer ones will have to small of a center bore there for the hubs on the. Front wheels will not fit. Try looking for toyota wheels
