4-1.10.7 Tire Maintenance. Tire and tube maintenance procedures outlined in
Rubber Manufacturers Association (RMA) publications for passenger, truck and bus,
off-highway, industrial, special purpose, and farm tires shall be used in maintaining
Navy vehicle and equipment tires. Tires shall be inspected and removed from service
in accordance with the safety standards prescribed in RMA publications. These
publications are available from the Rubber Manufacturers Association Inc., 1400 K
Street NW., Washington, DC 20005.
a. Retread Tires. Retreaded tires shall be used as replacement tires in
accordance with the EPA Guideline for the Federal Procurement of Retreaded Tires
and must be listed on the current issue of GSA's Qualified Products Lists (QPL);
QPL-22-T-381, QPL-22-T-410, QPL-22-T-1083, QPL-22-T-1619, for the particular tire
type. Worn tires that have been inspected and the casings found to be structurally
sound shall be retreaded for further use in accordance with the procedures established
below. Retreaded tires shall not be used on the front wheels of Buses, Ambulances, or
Aircraft Rescue Fire Fighting (ARFF) Vehicles. Re-grooving on tires is prohibited.
b. Tire Retreading Program. The use of retread tires can produce substantial
reduction in operating expenses of vehicles and equipment. Retreading services are available
in most areas under the prevailing GSA Federal Supply Schedule (FSG-26). In areas where
GSA schedules are not available for retreading services, it is recommended that a contract be
awarded for such service under competitive bidding procedures. Retreading is a labor-intensive
workmanship-oriented process and must be monitored closely and frequently. The following
procedures shall be followed in assuring quality retreads.
(1) Specification of Work. Tire retreading, repair, and material shall be in
accordance with Federal Specification ZZ-T-441H (6-13-89) entitled "Tire Pneumatic:
Retreaded and Repaired." Contractors shall furnish documentation showing their facility
is certified under GSA's Quality Assurance Facility Inspection Program (QAFIP). The
QAFIP certification shall be displayed in the contractor's business office and inspected
by the activity's representative to insure the certification is updated as required.
(2) Scope of Work. As in any retreading system, a retread is only as
good as its basic casing. Therefore, careful selection and stringent inspection
procedures must be followed. Inspection of the casings before and after retreading is
of prime importance for good quality control. Quality assurance shall be in accordance
with applicable paragraphs of Sections 3 and 4 of specification ZZ-T-441H, with the
following additional requirements:
(a) Before Retreading. Select premium tires for retreading that have
been well maintained during operation and have been pulled for retreading when tread
depth is not less that 4/32 of an inch deep on front-mounted tires and not less than 2/32
of an inch on all other tires. Casings, as furnished to the contractor, shall be identified
as Navy-owned and shall be further inspected by the contractor in accordance with
paragraph 3.3 of ZZ-T-441H before acceptance for retreading.
