I’m sorry but I don’t know or remember a lot of details on this car. I bought it from a friend who bought it from a guy that got the car brand new for a graduation gift and made a race car out of it. I bought it as a roller and fine tuned the chassis but didn’t build it. The guy did a beautiful job on the mini tubs and they almost looked stock. As with most of these car and even my black duster the air was removed to install the wheels and slicks then inflated. Almost positive they were 12 inch wheels (centerlines). Sorry I can’t help more.
