How can you make sure that your truck wheels turn freely with heavy loads?

To ensure that your truck wheels turn freely under heavy loads, regularly check and maintain proper tire pressure, as under-inflated tires can increase rolling resistance. Inspect wheel bearings and brakes for any signs of wear or damage, and lubricate them as necessary to reduce friction. Additionally, distribute the load evenly across the truck to prevent undue stress on any individual wheel. Lastly, ensure that the suspension system is in good condition to support heavy loads effectively.
