My 12.5 wheel is bent from car running over it in driveway.
is there a way to straighten it or buy a new one?
If it is a spoked wheel like bicycles have then as long as it is not bent too badly there is a chance that it could be trued by adjusting the tension of the spokes.
If it is an aluminum wheel then I do not think that it could be straightened after it is bent.
I can check and see if a new wheel is available. Do you know that model name of the scooter?
