LIMITED WARRANTY

FOR HEAVY DUTY TRUCKS, TRUCK TRAILERS,

BUSES, RV and MOTORHOME WHEELS

(Wheels with bead seat diameters measured in .5 inch

increments and Alcoa tube type wheels)

Alcoa warrants to the original purchaser, from Alcoa or its authorized distributor, that a
new Alcoa aluminum disc heavy duty truck, truck trailer, bus, 19.5-inch and 22.5-inch RV
or motorhome wheel is free from defects in material and workmanship. Alcoa agrees,
without charge, to repair or replace a wheel that fails in normal use and service because
of defects in material and workmanship. Truck, truck trailer, Dura-Flange

and the Dura-

Bright

surface treatment wheels not used in transit service are warranted for 60 months

from the date of manufacture as shown on the wheel except the Dura-Flange

rim flange

treatment is warranted for a period of 24 months. Alcoa bus mount wheels (10-hole,
11.25 inch bolt circle, 8.670 inch hub bore with 1.22 inch diameter bolt holes) and other
wheels used in transit service are warranted for 120 months from date of manufacture,
except the Dura-Bright

surface treatment on bus and transit service wheels is warranted

for a period of 60 months from the date of manufacture and the Dura-Flange

rim flange

treatment is warranted for 24 months. Satin finish, polished and Dura-Bright

surface

treatment 19.5-inch and 22.5-inch RV and motorhome wheels are warranted for 120
months from the date of manufacture as shown on the wheel. Alcoa does not warrant and
will not repair or replace or make adjustment with respect to any wheel that has been
subjected to misuse or abuse including the following:

(a) Using a tire that is oversized according to standards recommended by the Tire and

Rim Association, Inc. or other recognized tire and rim agencies such as ETRTO
(Europe) or others;

(b) Loading the wheel beyond the applicable maximum wheel load as specified by Alcoa;

(d) Changing the original condition of the wheel by alteration or by subjecting it to any

processing such as welding or straightening.

(e) Accidents, abnormal or severe operating conditions including without limitation tire

fires, brake fires, severe brake system drags or seizures or running with a flat tire; or

(f)

Failure to follow maintenance and other instructions and warnings set forth in the
Alcoa Heavy Duty Wheel Service Manual, Alcoa Technical Bulletins and other Alcoa
literature. Recommended maintenance includes, without limitation, using proper
torque, periodic cleaning, polishing, valve replacement, periodic inspection for
damage, loose lug nuts and rim flange wear inspections and procedures.

(g) Nicks, scratches and other surface blemishes resulting from improper maintenance,

cleaning, road debris, curbing, accident or operation are not warrantable.

(h) Damage due to cleaning with abrasives, abrasive brushes, steel wool, scouring pads,

or strong chemicals (acids or alkaline).

Dura-Bright® Surface Treated Wheels are warranted against:

(a) Filiform corrosion (worm or hair like lines, generally milky in appearance, underneath

surface protective treatment and emanating from damage to the surface treatment
such as nicks, scratches or damage from mounting hardware or wheel weights)

(b) Blistering due to loss of adhesion of the surface treatment,

If nicks, dings, scratches or other damage does occur to the Dura-Bright

treatment that

exposes the aluminum underneath, the metal exposed may naturally oxidize, but any
corrosion will be confined to the metal exposed and will not extend into or underneath the
Dura-Bright

treatment.

Normally, any washing materials or chemicals (including mild acid washes) that can
safely be used on a vehicle, its painted surfaces and components, can safely be used on
the Dura-Bright

surface treatment. The Dura-Bright

treatment prevents corrosion of

aluminum wheels and protects their shine. So long as the treatment remains in place (see
comments (g) and (h) above) and is maintained in accordance with the Alcoa Dura-
Bright

Care and Maintenance manual, it is warranted against corrosion. If corrosion does

occur within the treatment warranty period, subject to the limitations stated above, Alcoa
will replace any wheel exhibiting such corrosion.

There is no warranty that the wheel shall be merchantable or fit
for any particular purpose, nor is there any other warranty, express
or implied, except such as is expressly set forth herein.
Alcoa shall not be liable for any incidental or consequential
damages for any breach of warranty, its liability and the purchaser's
exclusive remedy being limited to repair or replacement of the wheel
as stated in this limited warranty.
