Tire Safety Modernization Act of 2026

This bill directs the Secretary of Transportation to update federal tire safety standards within one year. It would remove tire strength and bead unseating test requirements for passenger car and light truck radial tires, and remove tire strength tests for radial light truck and commercial tires. It would change the definition of "chunking" for snow tires, make visual evidence of chunking count as a failure in endurance and low-pressure tests, and require a review of the chunking definition for other tires. Within 180 days, the Secretary must set high-speed testing rules consistent with a United Nations tire regulation, and the Government Accountability Office must later report to Congress on the changes.
