Which practice can help reduce tire wear on trucks?

Regularly checking tire pressure is a crucial practice for reducing tire wear on trucks. Maintaining the correct tire pressure ensures that the tires are neither under-inflated nor over-inflated. Under-inflated tires can lead to increased contact with the road surface, causing excessive wear on the edges of the tires and potentially leading to blowouts. On the other hand, over-inflated tires can cause the center of the tire tread to wear prematurely.

Proper tire pressure helps maintain optimal tire performance, improves fuel efficiency, enhances vehicle handling, and prolongs the lifespan of the tires. Hence, this proactive maintenance practice is integral in ensuring that tires do not wear unevenly and have a longer service life.

The other options, while important for overall vehicle maintenance, do not directly address tire wear. Frequent oil changes primarily affect engine performance and longevity, adjusting engine timing relates to optimal engine operation, and cleaning air filters helps improve airflow but does not influence tire wear.
