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 a certification label is not available on the vehicle. It typically contains specific details provided by the vehicle manufacturer regarding the appropriate tire sizes, recommended tire pressures, and loading capacities based on the vehicle's design and specifications. Accessing the owner's manual ensures you are getting the correct information directly from the manufacturer, which is essential for maintaining safety and optimal vehicle performance.

While online forums can offer general advice from other vehicle owners and may provide useful tips, they do not guarantee accurate or manufacturer-specified information. Visiting a dealership could yield information, but relying on the owner's manual is more direct and efficient. Looking at the tire itself may offer details about the tire type and its maximum pressure, but it won’t provide comprehensive loading information specific to the vehicle. Therefore, the owner's manual is the best resource in this situation.
