They will bolt on, but may have a different offset (how far the wheel sits inboard or outboard). 4runner stand is 15mm, Tacoma ranges from 4mm to 30mm ~ the bigger numbers mean the wheel is tucked into the fender further, the smaller number the more chance the tire will "poke" out past the fender.

Look there to see if you can get the info based on the looks of the wheel. If it doesn't have the offset on that page, search the part number and you should be able to find the offset.
Or just slap them on and don't worry about it, it's worked fine for lots of people. I'm just super uptight about how things are Supposed to function together.
