I had a '99 Trooper and purchased a '01 VX, during which I swapped my Isuzu Trooper 16's with the 18's which worked out just great. The tires are over stock as well, they are Yokohama Geolander A/T+ II's - 265/70 16. And it is nice since the wheels are Isuzu and the suspension is stock, made this a cheap step up. Also just an FYI but when the VX came out in '99 the Isuzu 16's were the stock wheels and later the went to 18's.
