My recollection is that the original tires were 16x6.5--would be wise to verify. In any event, short of someone running your tire I would guess that you would have to mount one on a rim and put it on front and back and look see. If you already have the rims you might want to go to a used tire place and pay some guy five bucks to mount an old tire (of this size) for you and see if hits front or back. My guess is that height is probably not a problem unless u've lowered the truck but width could be a problem on front tie rods. Hopefully some one on this board has tried this size or is running them. Good luk.
