Looks like 4-Runners have always come with at least 16" wheels. You will have to do something to make more clearance as 16" trailer tires come in 80 & 85 profiles and are quite tall. Unless this 4-Runner has some aftermarket 15" wheels, you are probably going to have to do a lot of work and end up with results you aren't happy with.
