If you plan on keeping your front wheel drive Highlander for a few years, and why wouldn't you, get an set of Hakkapaliitta SUV 9 mounted on an extra set of rims and swap to them for the winters.
BTW, not all studded tires are created equally, there are still some tires out there (e.g. the ones used to compare Blizzak tires to on skating rinks) that are decades old technology.
