Tire information placards and vehicle certification labels contain information on tires and load limits. These labels indicate the vehicle manufacturer's information including:

• Recommended tire size
• Recommended tire inflation pressure
• Vehicle capacity weight (VCW–the maximum occupant and cargo weight a vehicle is designed to carry)
• Front and rear gross axle weight ratings (GAWR– the maximum weight the axle systems are designed to carry).

Both placards and certification labels are permanently attached to the trailer.
