## NHTSA's summary

This Preliminary Information communication provides information to the technician that some owners of Heavy Duty Trucks and Utilities may ask if they can lower their tire pressures. Tire pressures being set to the "Tire and Loading Label" will ensure the safe handling and ride characteristics of the truck and should not be lowered.
