The bolt circle on the wheels is the same but the center hole size and wheel offset must also be correct.
Even if the wheels fit, the tires’ overall diameter has to be close, and the width must be the same. There is often little or no clearance for wider tires in cars with MacPherson strut suspension.
Then there are the matters of whether you need new tires in the first place, the quality of the tires being offered, and how much of the debt he is proposing be satisfied by the tires and wheels. If this all seems complicated, it kind of is. I would stick to a cash settlement of the debt.
