Where should you look for tire and loading information if there is no certification label on the vehicle?

The owner's manual is the most reliable source for tire and loading information when there is no certification label on the vehicle. This manual typically contains all necessary specifications regarding tire pressure, load limits, and recommendations tailored to your specific vehicle model. Manufacturers provide detailed guidelines in the owner's manual to ensure proper maintenance and safety standards are met, including information on tire size and inflation requirements.

While online owner's forums can provide community-driven insights and advice, they may not always reflect accurate or manufacturer-recommended practices. Visiting a dealership may yield assistance, but this option relies on the availability of knowledgeable staff and may not always be convenient or feasible. Checking the tire itself usually only displays the maximum pressure and size, which is not the complete range of necessary information needed for safe operation. Therefore, referring to the owner's manual is the best course of action.
