My son wants to lift our '96 4Runner and run bigger tires. It's 4WD and has the stock 16" rims and 265/70/16 tires now. He has a set of almost new tires on steel 15x8 inch black 8 spoke wheels that are for a solid axle truck- they used to be on our '83 pickup. Would these fit and if not, could we grind the calipers down a little? I realize the offset will put the tires out some, that's okay with him as long as they bolt on. Thanks for your input.
