TOWCHECK FIELD GUIDE
How to read a tow vehicle door sticker
Open the driver door and locate the Tire and Loading Information label and certification label. Photograph both, then record the vehicle-specific occupant-and-cargo capacity, GVWR and front and rear GAWR exactly as printed.
The physical door labels identify ratings for that truck—not a better-equipped brochure example.
What the terms mean
GVWR is the manufacturer-specified loaded weight of one vehicle. GAWR is the specified capacity of one axle system. The occupant-and-cargo statement is the starting payload figure for that particular vehicle as built.
Worked example
Common mistakes
- Reading a label from another vehicle
- Confusing recommended cold tire pressure with the tire sidewall maximum
- Ignoring equipment installed after the vehicle left the factory
Frequently asked questions
Where are the labels?
Usually on the driver-side B-pillar, door edge or door opening, though placement varies.
Does the label include later accessories?
Not necessarily. Account for equipment added after manufacture according to applicable documentation.
Can a VIN decoder replace the physical label?
Use the physical label and official documentation for the exact vehicle whenever possible.
