Damn.. If changing an Ativa tire also a burden, you need to evaluate your spending and also your car choice. Seen too many case like this nowadays, example X70 users also brag about nice big 18" 19" sport rim, when want change tires say no budget ask got cheapo tire replacement or not.

Before you buy a car, you at least need to do some research like these basic maintenance, usually i will check and ask around before getting 1 so i can prepare upwards.

Bro, sure different price, so many different tire size & model even for 17" some wide, some thick, some is run flat type. If you want cheap, try ask those Thailand, Indonesia or China made tires but dont expect too much.
