Advice on changing from stock 14 inch rims and spacing

The "small bolt" wheels have been sold.

He still has the "big bolt" wheels. You have the "big bolt" pattern.

I got all excited and went back and looked and sadly they are 14 inch rims which I would really like 15 inch because for some reason in my area it is super hard to find tires for 14 inch rims😳
