My sons received a Mattel "cars" slot car ho set for Xmas from Santa.
The Lightning McQueen car has lost a couple of tires and needs new contacts.
Where can I buy stock tires and new copper contacts for this Mattel hpx2 chassis. I have no idea what size these tires are.
Thanks:)

Did you try sanding the contacts? I've been hitting mine with a fine abrasive wheel on my Dremel.
