Depends entirely on the car and the wheels. For cheaper cars with cheaper wheels it’s cheaper to have two sets of wheels instead of paying someone to dismount and mount your tires.
For a fancier car with expensive wheels, it’s generally going to be more expensive to buy another set of wheels than pay for 5 years of tire mounting.
