Tires have changed dramatically since many federal tests governing them were developed. Modern vehicles are heavier, electric powertrains deliver torque differently, and manufacturers are introducing designs that do not always fit older regulatory categories.
On October 26, 2026, the National Highway Traffic Safety Administration (NHTSA) announced a review of federal tire-safety requirements through a negotiated rulemaking committee. The effort will examine strength, bead-unseating, and endurance tests, as well as tire markings, load classifications, and non-pneumatic designs.
It is an important review, but not an immediate change to what drivers can buy or install: regulators are beginning a process that could eventually produce revised rules.
NHTSA Opens a Review of Longstanding Tire Tests
NHTSA’s announcement was followed by a formal Federal Register notice on October 27. The agency intends to establish a Tire Safety Negotiated Rulemaking Advisory Committee, with up to 18 stakeholders, to develop consensus recommendations for modernizing federal requirements.
The Department of Transportation calls this the first major update to federal tire standards in more than 20 years. The committee will provide guidance to the Secretary of Transportation and NHTSA, but it will not have the authority to introduce or enforce new regulations independently.
The review covers Federal Motor Vehicle Safety Standards Nos. 109, 119, and 139. These govern performance requirements for different categories of pneumatic tires, including passenger-car and light-vehicle tires and tires used on heavier vehicles.
The exact requirements differ by standard and application, so any revision must account for products designed for different loads and operating conditions.
Three established tests form a key part of the proposed agenda. The first is the tire strength test, also known as the plunger-energy test. During this procedure, a metal plunger is pushed into the tire tread until it penetrates the material. The amount of energy absorbed before penetration is used to measure the tire’s strength.
NHTSA wants stakeholders to assess whether the test remains necessary and whether its method reflects modern tire construction.
The second is the bead-unseating resistance test. A tire’s bead is the reinforced edge that seats against the wheel rim and helps maintain an airtight connection. The test evaluates the force required to push the bead away from the rim. Separation can cause rapid air loss and compromise vehicle control.
The third is the tire endurance test, including the issue known as chunking. Chunking occurs when pieces of tread material break away. Endurance procedures assess how a tire withstands sustained operation under prescribed loads and conditions.
NHTSA has not declared these tests obsolete or said they will be removed. It wants the committee to evaluate their continued effectiveness and whether alternative protocols could provide an appropriate safety assessment.
NHTSA sought public input on tire standards in a 2019 advance notice of proposed rulemaking. The current process continues that review and aims to produce consensus recommendations for a future proposal.
Modern SUVs, pickups, and EVs Raise New Tire Questions
Vehicle design is one reason the framework is being reconsidered. American buyers increasingly choose SUVs and pickups, while battery-electric vehicles add different engineering demands.
Tires must support vehicle weight, transfer acceleration and braking forces, maintain grip, dissipate heat, and resist damage. The balance varies with vehicle mass, torque, tire size, construction, and intended use.
EV battery packs add mass, while electric motors can deliver strong torque from low speeds. Load capacity, tread durability, rolling resistance, and noise therefore matter.
SUVs and pickups face additional demands when carrying cargo, towing, or travelling on rough surfaces. NHTSA will consider whether existing weight-limit guidelines and classifications adequately address modern vehicles.
One specific issue is a Tire and Rim Association petition concerning the inclusion of Load Range F light-truck tires in FMVSS No. 139. Load range is a classification associated with a tire’s load-carrying capability and inflation requirements. The committee will consider how these tires should be addressed within federal rules.
The committee will also examine tire sidewall markings. Sidewalls carry information that helps drivers and technicians identify a tire’s size, construction, load rating, and inflation requirements.
Clear markings matter because an unsuitable replacement tire can compromise handling or load capacity. NHTSA’s notice cites a Goodyear request for interpretation concerning the marking and testing of extra-load passenger tires with a maximum inflation pressure of 350 kPa.
This highlights the challenge of applying existing regulations to newer products, but it does not mean those tires are inherently unsafe.
Another topic is non-pneumatic, or airless, tires. Conventional tires rely on pressurized air, while non-pneumatic designs use structural elements to carry the vehicle. Some concepts use flexible spokes between the wheel and tread.
They could reduce conventional puncture risks but raise different questions about fatigue, heat, impact resistance, load capacity, and durability.
NHTSA wants the committee to consider how such products could fit federal safety requirements. This does not mean airless tires are about to become standard equipment or that pneumatic tires are being phased out.
The U.S. Tire Manufacturers Association has welcomed the review. Its president and CEO, Anne Forristall Luke, said some requirements date to 1960s tire technology and argued that standards should reflect current products. The committee must consider this industry view alongside technical evidence and other perspectives.
What Happens Next and What Drivers Should Expect
Negotiated rulemaking brings affected groups into discussions before NHTSA drafts a proposed regulation.
The Federal Register notice outlines up to 18 stakeholder positions: four for tire manufacturers or retailers, two for vehicle manufacturers, four for manufacturing associations, two for safety organizations, three for educational, research, or testing institutions, and three for engineering or standards-setting associations. NHTSA will also participate.
The committee would meet about four times a year, with additional meetings if needed, and could work for up to two years unless its charter is renewed. Meetings are expected to be public and virtual or hybrid. It will prepare consensus recommendations for NHTSA to review before any proposed rulemaking.
The agency is accepting comments on the committee’s scope and membership, along with nominations for committee positions. The deadline is November 27, 2026. Public comments can be submitted through Regulations.gov under Docket No. NHTSA-2026-1717. Membership applications should follow the contact instructions in the Federal Register notice.
For automakers and tire companies, revisions could affect design validation, laboratory testing, certification, and tire specifications. Updated procedures might clarify requirements for new materials and construction methods but could also require additional testing or product changes.
Drivers should not expect an immediate change at tire shops. The announcement does not ban existing tire models, require motorists to replace tires, or introduce new installation rules. Current federal requirements remain in place during the review.
Motorists should continue choosing tires that meet their vehicle manufacturer’s specifications, observing load and speed ratings, maintaining correct inflation, and replacing damaged or worn tires.
The cost implications are not yet known. NHTSA has described modernization as a way to improve safety and reduce costs but has not published a quantified estimate of savings for drivers or manufacturers.
More suitable tests and clearer requirements could reduce unnecessary regulatory burdens, while new testing or design requirements could add costs in some areas. The balance will become clearer only after recommendations and specific proposals are published.
The significance of this initiative is its attempt to bring tire regulation closer to the vehicles and products now on American roads. Heavier SUVs and pickups, electric powertrains, and non-pneumatic concepts raise questions that older procedures may not fully address.
NHTSA has started a consultation and consensus-building process but has not completed a rewrite. The next milestones will be the committee’s recommendations and any formal proposal that follows. Until then, existing standards remain in force.
