49 CFR Part 393

[Docket No. FMCSA-2025-0123]
RIN 2126-AC97


Parts and Accessories Necessary for Safe Operation; Tire Load 
Markings

AGENCY: Federal Motor Carrier Safety Administration (FMCSA), Department 
of Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: FMCSA proposes to revise the requirements for tires on 
commercial motor vehicles (CMVs) to clarify that the Federal Motor 
Carrier Safety Regulations (FMCSRs) do not require tire load 
restriction markings on their sidewalls. This change would eliminate 
confusion and clarify the scope of FMCSA's authority regarding the 
requirements for tires in the FMCSRs.

DATES: Comments must be received on or before July 29, 2025.

III. Legal Basis

    Under 49 U.S.C. 31136(a), DOT is required to ``prescribe minimum 
safety standards for commercial motor vehicles. At a minimum, the 
regulations shall ensure that--(1) commercial motor vehicles are 
maintained, equipped, loaded, and operated safely, (2) the 
responsibilities imposed on operators of commercial motor vehicles do 
not impair their ability to operate the vehicles safely; (3) the 
physical conditions of operators of commercial motor vehicles is 
adequate to enable them to operate the vehicles safely . . .; (4) the 
operation of commercial motor vehicles does not have a deleterious 
effect on the physical condition of the operators; and (5) an operator 
of a commercial motor vehicle is not coerced by a motor carrier, 
shipper, receiver, or transportation intermediary to operate a 
commercial motor vehicle in violation of a regulation promulgated under 
this

[[Page 22951]]

section, or chapter 51 or chapter 313 of this title.''
    This NPRM is based on the authority of 49 U.S.C. 31136(a)(1) to 
ensure that CMVs are equipped and operated safely. It does not 
implicate the driver-centered requirements of 49 U.S.C. 31136(a)(2) 
through (4). Because this NPRM would not impose any requirement on 
motor carriers, there is no obvious risk of coercion related to this 
rulemaking to which a driver might be subjected.
    The Administrator of FMCSA is delegated authority under 49 CFR 1.87 
to carry out the functions vested in the Secretary of Transportation by 
49 U.S.C. chapters 311, 313, and 315 as they relate to CMV operators, 
programs, and safety.
    For the reasons explained below, FMCSA believes that this proposed 
clarification of 49 CFR 393.75(g) and (h) would not adversely affect 
the operational safety of CMVs.

IV. Background

    Requirements that CMVs be equipped with various parts and 
accessories are established in 49 CFR part 393. Specifically, Sec.  
393.75 contains requirements for tires on CMVs and paragraphs (g) and 
(h) of that section prohibit operating motor vehicles and manufactured 
homes with weights in excess of the maximum tire load marked on the 
sidewall of a tire.

V. Discussion of Proposed Rulemaking

    FMCSA proposes to clarify the requirements in Sec.  393.75(g) and 
(h) by explicitly stating that those paragraphs do not require 
manufacturers to add markings to the sidewalls of tires. The 
requirements for manufacturers to add markings to the sidewalls of 
tires fall within the National Highway Traffic Safety Administration's 
(NHTSA) regulatory authority. Tires subject to Sec.  393.75 generally 
must be manufactured in accordance with Federal Motor Vehicle Safety 
Standard (FMVSS) No. 119 (49 CFR 571.119). NHTSA requires those tires 
to be marked with a maximum load rating on the sidewall (Sec.  571.119 
S6.5). The markings required by FMVSS No. 119 are then referenced in 
Sec.  393.75(g) and (h). If those markings are absent for any reason, 
Sec.  393.75(g) and (h) then refer back to FMVSS No. 119 for a list of 
publications which contain the necessary tire load limit information.
    This clearly shows that NHTSA, not FMCSA, is the agency which 
imposes requirements on tire manufacturers to add maximum load rating 
markings to the sidewalls of tires. However, FMCSA is aware of 
instances where members of the regulated public have mistakenly 
believed that Sec.  393.75(g) and (h) require sidewall markings, and 
that markings missing from the sidewall would be a violation of those 
requirements. Sections 393.75(g) and (h) require that motor vehicles 
and manufactured homes are not operated with a weight in excess of the 
load limits on the sidewalls of the tires, or, for manufactured homes 
built before January 1, 2002, with a weight more than 18 percent over 
the load limits. The markings on the sidewalls of the tires provide the 
information to determine when a vehicle is in violation of those 
requirements, but the markings themselves are not required by the 
FMCSRs. Therefore, FMCSA is adding a new paragraph (j) to Sec.  393.75 
to clarify that FMCSA does not require tire markings and to avoid any 
further confusion about the scope and requirements of paragraphs (g) 
and (h).

VI. International Impacts

    Motor carriers and drivers are subject to the laws and regulations 
of the countries that they operate in, unless an international 
agreement states otherwise. Drivers and carriers should be aware of the 
regulatory differences between nations.

VII. Section-by-Section Analysis

    This section-by-section analysis describes the proposed changes in 
numerical order.


Sec.  393.75  Tires.

    FMCSA proposes to add a new paragraph (j) to clarify that FMCSA 
does not requiring tire markings under paragraphs (g) and (h).

VIII. Regulatory Analyses

A. Executive Order (E.O.) 12866 (Regulatory Planning and Review), E.O. 
13563 (Improving Regulation and Regulatory Review), and DOT Regulatory 
Policies and Procedures

    FMCSA has considered the impact of this NPRM under E.O. 12866 (58 
FR 51735, Oct. 4, 1993), Regulatory Planning and Review, E.O. 13563 (76 
FR 3821, Jan. 21, 2011), Improving Regulation and Regulatory Review, 
and DOT Regulatory Policies and Procedures. The Office of Information 
and Regulatory Affairs within the Office of Management and Budget (OMB) 
determined that this NPRM is not a significant regulatory action under 
section 3(f) of E.O. 12866, as supplemented by E.O. 13563, and does not 
require an assessment of potential costs and benefits under section 
6(a)(3) of that order. Accordingly, OMB has not reviewed it under that 
E.O.
    FMCSA proposes to clarify the requirements in Sec.  393.75(g) and 
(h) by explicitly stating that those paragraphs do not require 
manufacturers to add markings to the sidewalls of tires. This proposal 
benefits the public by clarifying misunderstandings for affected 
entities, such as owners and operators of CMVs.
    As NHTSA requires tires to be marked with a maximum load rating on 
the sidewall of the tire, FMCSA finds that members of the regulated 
public would not change their behavior due to this proposed rule. 
However, the increased clarity provided by this proposed rule could 
result in de minimis cost savings for regulated entities when 
navigating their obligations under the FMCSRs. The Agency requests 
comment on any impacts that could result from the revisions proposed in 
this NPRM.

B. E.O. 14192 (Unleashing Prosperity Through Deregulation)

    E.O. 14192 (90 FR 9065, Jan. 31, 2025), Unleashing Prosperity 
Through Deregulation, requires that for ``each new [E.O. 14192 
regulatory action] issued, at least ten prior regulations be identified 
for elimination.'' \1\
---------------------------------------------------------------------------

    \1\ Executive Office of the President. Executive Order 14192 of 
January 31, 2025. Unleashing Prosperity Through Deregulation. 90 FR 
9065-9067. Feb. 6, 2025.
---------------------------------------------------------------------------

    Implementation guidance for E.O. 14192 issued by OMB (Memorandum M-
25-20, March 26, 2025) defines two different types of E.O. 14192 
actions: an E.O. 14192 deregulatory action, and an E.O. 14192 
regulatory action.\2\
---------------------------------------------------------------------------

    \2\ Executive Office of the President. Office of Management and 
Budget. Guidance Implementing Section 3 of Executive Order 14192, 
Titled ``Unleashing Prosperity Through Deregulation.'' Memorandum M-
25-20. March 26, 2025.
---------------------------------------------------------------------------

    An E.O. 14192 deregulatory action is defined as ``an action that 
has been finalized and has total costs less than zero.'' This proposed 
rulemaking is expected to have total costs less than zero, and 
therefore would be considered an E.O. 14192 deregulatory action upon 
issuance of a final rule.

C. Advance Notice of Proposed Rulemaking

    Under 49 U.S.C. 31136(g), FMCSA is required to publish an advance 
notice of proposed rulemaking (ANPRM) or proceed with a negotiated 
rulemaking, if a proposed safety rule ``under this part'' \3\ is likely 
to lead to the promulgation of a major rule.\4\ As this

[[Page 22952]]

proposed rule is not likely to result in the promulgation of a major 
rule, the Agency is not required to issue an ANPRM or to proceed with a 
negotiated rulemaking.
---------------------------------------------------------------------------

    \3\ Part B of Subtitle VI of Title 49, United States Code, i.e., 
49 U.S.C. chapters 311-317.
    \4\ A major rule means any rule that the Office of Management 
and Budget finds has resulted in or is likely to result in (a) an 
annual effect on the economy of $100 million or more; (b) a major 
increase in costs or prices for consumers, individual industries, 
geographic regions, Federal, State, or local government agencies; or 
(c) significant adverse effects on competition, employment, 
investment, productivity, innovation, or on the ability of United 
States-based enterprises to compete with foreign-based enterprises 
in domestic and export markets (5 U.S.C. 804(2)).
---------------------------------------------------------------------------

D. Regulatory Flexibility Act

    The Regulatory Flexibility Act (5 U.S.C. 601 et seq.), as amended 
by the Small Business Regulatory Enforcement Fairness Act of 1996,\5\ 
requires Federal agencies to consider the effects of the regulatory 
action on small business and other small entities and to minimize any 
significant economic impact. The term small entities comprises small 
businesses and not-for-profit organizations that are independently 
owned and operated and are not dominant in their fields, and 
governmental jurisdictions with populations of less than 50,000 (5 
U.S.C. 601(6)). Accordingly, DOT policy requires an analysis of the 
impact of all regulations on small entities, and mandates that agencies 
strive to lessen any adverse effects on these businesses.
---------------------------------------------------------------------------

    \5\ Public Law 104-121, 110 Stat. 857 (Mar. 29, 1996).
---------------------------------------------------------------------------

    No regulatory flexibility analysis is required, however, if the 
head of an Agency or an appropriate designee certifies that the rule 
will not have a significant economic impact on a substantial number of 
small entities. This proposed rulemaking would clarify the requirements 
in Sec.  393.75(g) and (h) by explicitly stating that those paragraphs 
do not require manufacturers to add markings to the sidewalls of tires. 
Regulated entities would not change their behavior in response to this 
proposed rule as NHTSA requires manufacturers to add markings to the 
sidewalls of tires. De minimis cost savings could be realized by 
entities through the clarification of the FMCSRs.
    Consequently, I certify that the proposed action would not have a 
significant economic impact on a substantial number of small entities.

E. Assistance for Small Entities

    In accordance with section 213(a) of the Small Business Regulatory 
Enforcement Fairness Act of 1996 (Pub. L. 104-121, 110 Stat. 857), 
FMCSA wants to assist small entities in understanding this proposed 
rule so they can better evaluate its effects on themselves and 
participate in the rulemaking initiative. If the proposed rule would 
affect your small business, organization, or governmental jurisdiction 
and you have questions concerning its provisions or options for 
compliance, please consult the person listed under FOR FURTHER 
INFORMATION CONTACT.
    Small businesses may send comments on the actions of Federal 
employees who enforce or otherwise determine compliance with Federal 
regulations to the Small Business Administration's Small Business and 
Agriculture Regulatory Enforcement Ombudsman (Office of the National 
Ombudsman, see https://www.sba.gov/about-sba/oversight-advocacy/office-national-ombudsman) and the Regional Small Business Regulatory Fairness 
Boards. The Ombudsman evaluates these actions annually and rates each 
agency's responsiveness to small business. If you wish to comment on 
actions by employees of FMCSA, call 1-888-REG-FAIR (1-888-734-3247). 
DOT has a policy regarding the rights of small entities to regulatory 
enforcement fairness and an explicit policy against retaliation for 
exercising these rights.

F. Unfunded Mandates Reform Act of 1995

    The Unfunded Mandates Reform Act of 1995 (2 U.S.C. 1531-1538) 
(UMRA) requires Federal agencies to assess the effects of their 
discretionary regulatory actions. The Act addresses actions that may 
result in the expenditure by a State, local, or Tribal government, in 
the aggregate, or by the private sector of $206 million (which is the 
value equivalent of $100 million in 1995, adjusted for inflation to 
2024 levels) or more in any 1 year. Because this proposed rule would 
not result in such an expenditure, a written statement is not required.

G. Paperwork Reduction Act

    This proposed rule contains no new information collection 
requirements under the Paperwork Reduction Act of 1995 (44 U.S.C. 3501-
3520).

H. E.O. 13132 (Federalism)

    A rule has implications for federalism under section 1(a) of E.O. 
13132 if it has ``substantial direct effects on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government.''
    FMCSA has determined that this rulemaking would not have 
substantial direct costs on or for States, nor would it limit the 
policymaking discretion of States. Nothing in this document preempts 
any State law or regulation. Therefore, this rulemaking does not have 
sufficient federalism implications to warrant the preparation of a 
Federalism Impact Statement.

I. Privacy

    The Consolidated Appropriations Act, 2005,\6\ requires the Agency 
to assess the privacy impact of a regulation that will affect the 
privacy of individuals. This NPRM would not require the collection of 
personally identifiable information.
---------------------------------------------------------------------------

    \6\ Public Law 108-447, 118 Stat. 2809, 3268, note following 5 
U.S.C. 552a (Dec. 4, 2014).
---------------------------------------------------------------------------

    The Privacy Act (5 U.S.C. 552a) applies only to Federal agencies 
and any non-Federal agency that receives records contained in a system 
of records from a Federal agency for use in a matching program.
    The E-Government Act of 2002,\7\ requires Federal agencies to 
conduct a Privacy Impact Assessment (PIA) for new or substantially 
changed technology that collects, maintains, or disseminates 
information in an identifiable form. No new or substantially changed 
technology would collect, maintain, or disseminate information as a 
result of this rulemaking. Accordingly, FMCSA has not conducted a PIA.
---------------------------------------------------------------------------

    \7\ Public Law 107-347, sec. 208, 116 Stat. 2899, 2921 (Dec. 17, 
2002).
---------------------------------------------------------------------------

    In addition, the Agency will complete a Privacy Threshold 
Assessment (PTA) to evaluate the risks and effects the proposed 
rulemaking might have on collecting, storing, and sharing personally 
identifiable information. The PTA will be submitted to FMCSA's Privacy 
Officer for review and preliminary adjudication and to DOT's Privacy 
Officer for review and final adjudication.

J. E.O. 13175 (Indian Tribal Governments)

    This rulemaking does not have Tribal implications under E.O. 13175, 
Consultation and Coordination with Indian Tribal Governments, because 
it does not have a substantial direct effect on one or more Indian 
Tribes, on the relationship between the Federal Government and Indian 
Tribes, or on the distribution of power and responsibilities between 
the Federal Government and Indian Tribes.

K. National Environmental Policy Act of 1969

    FMCSA analyzed this proposed rule pursuant to the National 
Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.). The Agency 
believes this proposed rule, if finalized, would not have a reasonably 
foreseeable significant effect on the quality of the human

[[Page 22953]]

environment. This action would likely fall under a published 
categorical exclusion and thus be excluded from further analysis and 
documentation in an environmental assessment or environmental impact 
statement under FMCSA Order 5610.1 (69 FR 9680), Appendix 2. 
Specifically, paragraph (6)(bb), which covers regulations pertaining to 
vehicle operation safety standards, equipment approval, and/or 
equipment carriage requirements. The public is invited to comment on 
the impact of the proposed Agency action.

L. Rulemaking Summary

    In accordance with 5 U.S.C. 553(b)(4), a summary of this proposed 
rule may be found at regulations.gov, under the docket number.
