Yes the traction tires can only be used for 5 months but that doesn't help him right now if he needed to use them because of the law stating nov thru mar usage.
Just stop by a tire place and pick up a set. About $50. Better than the alternative. Also weather up in the mountains changes fast and chain up appear out of nowhere. In other words you might just need them.
Your best bet would be to drive for an owner in the type of vehicle you are interested in. Then you can see if this type of work is for you. Hope this helps.
