Thomas and the New Wheel is a magazine story.
When Bertie gets a flat tyre, Thomas takes his passengers for him in Annie and Clarabel and he tells Bertie that he should not have any problem with his own wheels. But the following morning, Thomas is taking goods when his front-left driving wheel strikes a huge rock beside the track, and this wheel makes a strange noise when he takes Annie and Clarabel that afternoon. Bertie takes Thomas' passengers whilst Thomas goes to the Works. It turns out that the rock had damaged his front-left driving wheel, so he gets a new one put in place. After his repairs, Thomas tells Bertie that a damaged wheel might happen to any engine.
