Found this weird pattern after testing a couple of my pancake chassis. Never had this happen before on any car, tires must be getting old on the cars that did this...  Tires shake?? |

do you store your cars with slip on silicon tires on the wheels?
this can cause them, like a rubber band, to stretch a little.
and worse than lifting the shoes off the rail is hopping the tires.
also, you are aware of the torque effect that the armature puts on the car ( the reason helicopters have a rear rotor ), which can cause one side of the car to "dig" a little better and the other tire to lift.
aside from the possible slippage of the tires on the rims, your pics show that the car is slipping a little sideways on launch.
LOL, don't they all! LOL
if you have tried gluing the tires, then, they are coming off, but not the whole way around the rim.
other perceptions?

Have not tried to find out which car/s did this as I ran about 10 different ones. I know what you mean about the torque effect as pancake cars with poor traction always twist in opposite rotation to the direction of the armature. This is a similar effect to the full size rwd cars lifting one of the rear tires due to the torque put on the driveshaft. I have had some cars with older silicon tires actually break off the rim after being stored for awhile. I think the car that did this had older rubber tires on it.
