How should a commercial driver react if an onboard wheel fire or tire fire occurs while driving?

1. Stop in a safe open area away from structures or other vehicles, evacuate passengers, call emergency services, and use a Class ABC dry powder extinguisher
2. Keep driving to the next town so the vehicle can be dealt with at a workshop
3. Throw water over the burning tyre from the roadside water carrier
4. Park close to other vehicles so their drivers can help fight the fire
