not really,one tired changing, can get tire from junk yard, u can get it at $20 each deal, then have it done in a gas station, balance the wheel, for another $5.
Above is for old car, i treat old car as for used tires, (of cause u need to know how to pick some good one)
unless u get all 4 new wheels or car start shaking like crazy when u drive over 80, scrue the 4 wheel Alighment.
