I think it was the Ford Explorer/Firestone tire incidents.
Yep. The Transportation Recall Enhancement, Accountability, and Documentation (TREAD) Act of 2000 Section 11 was the law that required manufacturers to put tire inflation and load limit stickers on vehicles which was due to the Firestone/Ford recall of the late 90s.
Transportation Recall Enhancement, Accountability, and Documentation Act wrote:
SEC. 11. IMPROVED TIRE INFORMATION.
(a) TIRE LABELING.—Within 30 days after the date of the enactment of this Act, the Secretary of Transportation shall initiate a rulemaking proceeding to improve the labeling of tires required by section 30123 of title 49, United States Code to assist consumers in identifying tires that may be the subject of a decision under section 30118(b) or a notice required under section 30118(c). The Secretary shall complete the rulemaking not later than June 1, 2002.
(b) INFLATION LEVELS AND LOAD LIMITS.—In the rulemaking initiated under subsection (a), the Secretary may take whatever additional action is appropriate to ensure that the public is aware of the importance of observing motor vehicle tire load limits and maintaining proper tire inflation levels for the safe operation of a motor vehicle. Such additional action may include a requirement that the manufacturer of motor vehicles provide the purchasers of the motor vehicles information on appropriate tire inflation levels and load limits if the Secretary determines that requiring such manufacturers to provide such information is the most appropriate way such information can be provided.
Before this, there was no such thing as an inflation and load rating label. The label was meant for manufacturers to inform the public of recommended inflation and load limits of the tires, and NOT as some sort of law binding rating that law enforcement can enforce like some believe. Nor does this rating stay with the vehicle since changing the original tires to ones that have a different load rating will make the number on this sticker invalid.
