Thanks everyone. If you need to see the wheels just google WCM 1/4 sprint. These are both factory stock cars Made in USA. Nope, these aren't go-kart wheels, much smaller. Anyways what does it matter if you see lug nuts, hubs and axles? I'm looking for replacement tires not wheels, axles or hubs.
Thanks Striikar ebay might be my best shot. WCM doesn't have them either anymore since they changed their tire/wheel design to a plastic 4-bolt style. These cats date back to the 1990's and I think sometime in the last several years WCM changed the wheel/tire design on their new offerings.
