Hi there...I have two new 1/32 Carrera digital cars (BMW Procar & Ford Capri Zakspeed) that are making a lot of noise on the track with and without a chassis. I can't see any issues in the mechanical aspects, everything seems to turn freely and nothing is rubbing. Can it be just the tires out of round out of the box? I have a video but I only see that you can upload photos. Thanks in advance for any help or suggestions.
