NHTSA Plans New Tire Safety Standards for U.S. Vehicles

The National Highway Traffic Safety Administration (NHTSA) has announced plans to modernize federal tire safety standards for the first time in more than 20 years. The initiative could eventually affect how commercial truck tires are tested, classified, and labeled.

The agency plans to review existing tire testing methods, consider newer tire technologies, and examine tire load classifications. The review includes standards that apply to heavy commercial truck tires.

How Tire Safety Standards Could Affect Commercial Trucks

Federal tire safety standards establish minimum performance requirements for tires sold in the United States. One of the standards under review is Federal Motor Vehicle Safety Standard (FMVSS) No. 119. It covers new pneumatic tires used on vehicles other than passenger cars, including many commercial trucks and buses.

For the trucking industry, the review could eventually affect tire manufacturers, equipment suppliers, and fleets purchasing replacement tires. NHTSA is examining whether existing testing procedures remain appropriate for modern tire designs.

The agency is also considering changes to tire markings and certain load classifications. These areas are important for commercial trucking because tires must be suitable for the weight carried by a vehicle and the conditions under which it operates. However, the agency has not proposed specific changes to the tire requirements currently used by commercial carriers.

NHTSA Reviews Tire Strength and Endurance Tests

The proposed modernization effort includes three major testing areas.

Tire strength testing: NHTSA plans to examine whether existing tests adequately evaluate a tire’s resistance to damage from applied forces.

Bead unseating resistance: The agency will review tests involving the ability of a tire bead to remain seated against the wheel rim.

Tire endurance testing: Regulators will evaluate whether existing procedures adequately measure tire performance under repeated loading and operating conditions.

These tests are addressed in federal standards Nos. 109, 119, and 139. According to the Federal Register notice, NHTSA wants to determine whether the existing methods remain necessary and effective. The agency has received industry feedback questioning whether certain longstanding testing procedures accurately reflect modern tire designs.

Any future changes could affect the testing and certification requirements manufacturers must satisfy before selling tires. For commercial drivers, the potential impact would depend on which standards are revised and how manufacturers respond.

New Tire Technologies and Load Classifications Under Review

Another part of the initiative involves newer tire designs and tire identification requirements. NHTSA plans to consider how federal regulations should address non-pneumatic tires, sometimes called airless tires. Unlike conventional tires, these designs do not rely on compressed air to support the vehicle.

The agency also plans to examine tire sidewall markings and certain load classifications. One issue specifically identified in the Federal Register notice is a petition from the Tire and Rim Association involving Load Range F light-truck tires under FMVSS No. 139.

That proposal concerns a particular light-truck tire classification. It should not be confused with a proposal to change federal gross vehicle weight limits for Class 8 trucks.

For trucking fleets, clear tire markings and load classifications remain important when selecting tires suitable for specific vehicles and applications. However, it is too early to determine whether the review will change the types of commercial truck tires available or their prices.

Tire Manufacturers Support Updating Federal Rules

The U.S. Tire Manufacturers Association (USTMA) has expressed support for the federal initiative. In an October 26 statement, USTMA President and CEO Anne Forristall Luke said existing federal testing standards were developed around much older tire technologies.

The association argues that modernizing those requirements could make it easier for manufacturers to introduce newer tire designs already available in other markets. USTMA also said its members look forward to contributing technical expertise during the rulemaking process.

These statements reflect the tire industry’s position. NHTSA has not yet determined whether the proposed modernization will reduce tire costs or improve performance in specific commercial trucking applications. Those questions will depend on the technical recommendations and any regulations ultimately adopted.

NHTSA Plans Committee to Review Tire Regulations

Rather than immediately publishing a proposed rule, NHTSA plans to establish a negotiated rulemaking advisory committee. The committee would bring together representatives from affected industries and organizations to develop recommendations. Transportation Secretary Sean Duffy is expected to appoint up to 18 members.

The proposed membership includes representatives from:

• Tire manufacturers and retailers.
• Motor vehicle manufacturers.
• Vehicle equipment manufacturers.
• Safety organizations.
• Research and testing institutions.
• Engineering and standards organizations.

The committee would examine existing regulations and attempt to reach agreement on recommended changes. According to the Federal Register notice, it is expected to meet approximately four times annually and could operate for up to two years. If the committee reaches a consensus, NHTSA would use its recommendations to help develop a proposed rule. That proposal would still undergo the federal rulemaking process, including public comment, before any final requirements could take effect.

Public Comments Accepted Through November 27

NHTSA is accepting public comments on the proposed committee’s responsibilities and membership. The agency is also accepting nominations from qualified individuals interested in serving on the committee. Both deadlines fall on November 27, 2026. Committee membership applications must arrive by 5 p.m. Eastern time.

Public comments can be submitted through Regulations.gov under Docket No. NHTSA-2026-1717. The comment period is focused on establishing the committee and determining which interests should be represented. It is not a comment period on a completed set of new tire safety rules.

What Truck Drivers Should Know About the Proposed Changes

The tire safety initiative could eventually influence how commercial vehicle tires are manufactured, tested, and labeled. However, the announcement does not change existing tire inspection or maintenance requirements for truck drivers.

Commercial drivers and carriers must continue following applicable federal regulations concerning tire condition, tread depth, inflation, load capacity, and vehicle safety. The review also does not establish new requirements for tire replacement, retreading, or roadside inspections.

For now, the most significant development is that NHTSA is formally reconsidering longstanding federal tire standards, including requirements that apply to commercial trucks. The next step will be establishing the advisory committee and reviewing public feedback. Any actual changes affecting commercial truck tires would require further regulatory action.
