PIB TIP: MAINTAIN PROPER INFLATION. Maintaining correct inflation is free and is the highest saving maintenance you can perform on your truck. Improper inflation is by far the greatest reason that tires fail or wear out early, also wasting fuel. Daily pre- and post-trip inspections give owner-operators the chance to check pressures and look for leaks, punctures, broken valve stems or nails. Metal valve caps tend to withstand wear and tear better than plastic ones.
