Are spacers a good idea when rims scratch caliper? (Can not afford new tires)

What is your question?

Rims are a size 7Jx15 And scratches the caliper forcing the wheels to not spin. I don't have enough money to buy new tires so I was wondering if I could just use spacers without worrying of more damage

How long has your 2000 BMW 328i had this problem?

Ever since I was given the car
