FUEL EFFICIENCY. 
(a) STANDARDS FOR TIRES MANUFACTURED FOR 
INTERSTATE COMMERCE.—Section 30123 of title 49, 
United States Code, is amended— 
(1) in subsection (b), by inserting after the first 
sentence the following: ‘‘The grading system shall 
include standards for rating the fuel efficiency of 
tires designed for use on passenger cars and light 
trucks.’’; and 
(2) by adding at the end the following: 
‘‘(d) NATIONAL
TIRE
FUEL
EFFICIENCY
PRO-
GRAM.—(1) The Secretary shall develop and carry out a 
national tire fuel efficiency program for tires designed for 
use on passenger cars and light trucks. 
‘‘(2) The program shall include the following: 
‘‘(A) Policies and procedures for testing and la-
beling tires for fuel economy to enable tire buyers to 
make informed purchasing decisions about the fuel 
economy of tires. 
‘‘(B) Policies and procedures to promote the 
purchase of energy-efficient replacement tires, in-
cluding purchase incentives, website listings on the 
Internet, printed fuel economy guide booklets, and 
mandatory requirements for tire retailers to provide 
tire buyers with fuel-efficiency information on tires.
‘‘(C) Minimum fuel economy standards for 
tires, promulgated by the Secretary. 
‘‘(3) The minimum fuel economy standards for tires 
shall— 
‘‘(A) ensure, in conjunction with the require-
ments under paragraph (2)(B), that the average fuel 
economy of replacement tires is equal to or better 
than the average fuel economy of tires sold as origi-
nal equipment; 
‘‘(B) secure the maximum technically feasible 
and cost-effective fuel savings; 
‘‘(C) not adversely affect tire safety; 
‘‘(D) not adversely affect the average tire life of 
replacement tires; 
‘‘(E) incorporate the results from— 
‘‘(i) laboratory testing; and 
‘‘(ii) to the extent appropriate and avail-
able, on-road fleet testing programs conducted 
by the manufacturers; and 
‘‘(F) not adversely affect efforts to manage 
scrap tires. 
‘‘(4) The policies, procedures, and standards devel-
oped under paragraph (2) shall apply to all types and 
models of tires that are covered by the uniform tire quality
grading standards under section 575.104 of title 49, Code 
of Federal Regulations (or any successor regulation). 
‘‘(5) Not less often than every three years, the Sec-
retary shall review the minimum fuel economy standards 
in effect for tires under this subsection and revise the 
standards as necessary to ensure compliance with require-
ments under paragraph (3). The Secretary may not, how-
ever, reduce the average fuel economy standards applica-
ble to replacement tires. 
‘‘(6) Nothing in this chapter shall be construed to 
preempt any provision of State law relating to higher fuel 
economy standards applicable to replacement tires de-
signed for use on passenger cars and light trucks. 
‘‘(7) Nothing in this chapter shall apply to— 
‘‘(A) a tire or group of tires with the same 
SKU, plant, and year, for which the volume of tires 
produced or imported is less than 15,000 annually; 
‘‘(B) a deep tread, winter-type snow tire, space- 
saver tire, or temporary use spare tire; 
‘‘(C) a tire with a normal rim diameter of 12 
inches or less; 
‘‘(D) a motorcycle tire; or 
‘‘(E) a tire manufactured specifically for use in 
an off-road motorized recreational vehicle.
