Sec. 571.117  Standard No. 117; Retreaded pneumatic tires.

    S1. Scope. This standard specifies performance, labeling, and 
certification requirements for retreaded pneumatic passenger car tires.
    S2. Purpose. The purpose of this standard is to require retreaded 
pneumatic passenger car tires to meet safety criteria similar to those 
for new pneumatic passenger car tires.
    S3. Application. This standard applies to retreaded pneumatic tires 
for use on passenger cars manufactured after 1948.
    S4. Definitions.

[[Page 367]]

    S4.1 Casing means a used tire to which additional tread may be 
attached for the purpose of retreading.
    Retreaded means manufactured by a process in which a tread is 
attached to a casing.
    S4.2 All terms defined in Sec. Sec. 571.109 and 571.110 are used as 
defined therein.
    S5. Requirements.
    S5.1 Retreaded tires.
    S5.1.1 Except as specified in S5.1.3, each retreaded tire, when 
mounted on a test rim of the width specified for the tire's size 
designation in appendix A of Sec. 571.109 shall comply with the 
following requirements of Sec. 571.109:
    (a) S4.1 (Size and construction).
    (b) S4.2.1 (General).
    (c) S4.2.2.3 (Tubeless tire resistance to bead unseating).
    (d) S4.2.2.4 (Tire strength).
    S5.1.2 Except as specified in S5.1.3, each retreaded tire, when 
mounted on a test rim of the width specified for the tire's size 
designation in appendix A of Sec. 571.109, shall comply with the 
requirements of S4.2.2.2 of Sec. 571.109, except that the tire's 
section width shall not be more than 110 percent of the section width 
specified, and the tire's size factor shall be at least 97 percent of 
the size factor specified, in appendix A of Sec. 571.109 for the tire's 
size designation.
    S5.1.3 Each retreaded tire shall be capable of meeting the 
requirements of S5.1.1 and S5.1.2 when mounted on any rim in accordance 
with those sections.
    S5.1.4 No retreaded tire shall have a size designation, recommended 
maximum load rating, or maximum permissible inflation pressure that is 
greater than that originally specified on the casing pursuant to S4.3 of 
Sec. 571.109, or specified for the casing in Table I.
    S5.2 Casings.
    S5.2.1 No retreaded tire shall be manufactured with a casing--
    (a) On which bead wire or cord fabric is exposed before processing.
    (b) On which any cord fabric is exposed during processing, except 
that cord fabric that is located at a splice, i.e., where two or more 
segments of the same ply overlap, or cord fabric that is part of the 
belt material, may be exposed but shall not be penetrated or removed to 
any extent whatsoever.
    S5.2.2 No retreaded tire shall be manufactured with a casing--
    (a) From which a belt or ply, or part thereof, is removed during 
processing; or
    (b) On which a belt or ply, or part thereof, is added or replaced 
during processing.
    S5.2.3 Each retreaded tire shall be manufactured with a casing that 
bears, permanently molded at the time of its original manufacture into 
or onto the tire sidewall, each of the following:
    (a) The symbol DOT;
    (b) The size of the tire; and
    (c) The actual number of plies or ply rating.
    S5.2.4 [Reserved]
    S6. Certification and labeling.
    S6.1 Each manufacturer of a retreaded tire shall certify that its 
product complies with this standard pursuant to Section 30115 of Title 
49, United States Code, by labeling the tire with the symbol DOT in the 
location specified in section 574.5 of this chapter.
    S6.2 [Reserved]
    S6.3 Each retreaded tire shall bear permanent labeling through 
molding, branding, or other method that will produce a permanent label, 
or through the retention of the original casing labeling, in at least 
one location on the tire sidewall, in letters and numbers not less than 
2 mm (0.078 inch) high, consisting of the following information:
    (a) The tire's size designation;
    (b) The tire's maximum permissible inflation pressure, either as it 
appears on the casing or as set forth in Table 1;
    (c) The tire's maximum load, either as it appears on the casing or 
as set forth in Table 1;
    (d) The actual number of plies in or the ply rating of the tire 
sidewall and, if different, the actual number of plies in or the ply 
rating of the tread area;
    (e) The generic name of each cord material used in the plies of both 
sidewall and the tread area of the tire;
    (f) The word ``tubeless'' if the tire is a tubeless tire, or the 
words ``tube-type'' if the tire is a tube-type tire;
    (g) If the tire is of bias/belted construction, the words ``bias/
belted;''
    (h) If the tire is of radial construction, the word ``radial.''

[[Page 368]]

    The information shall either be retained from the casing used in the 
manufacture of the tire, or may be labeled onto the tire during the 
retreading process.
