so i have 245/65/17 all around...however i have no spare so i have been looking to buy one. my winch/hoist end (the part that actually holds the tire in place rusted and fell off). i found one and its a 16" six lug full size spare tire on rim. Measures 245/70/16 with unused tread. would this be ok if i was stranded out somewhere? its a steal at 30 bucks. its in rhode island and im in mass but idont care.
