The ones in the render look like tire 89201 with (I am assuming) hub 55982. If you want to acquire some, you can find both easily on Bricklink for cheap. If you haven't used Bricklink before and have questions, feel free to ask.

I tested those parts with a one-stud gap between the wheel axle and the white axle in the image below. There's plenty of gap. Hope this helps.
