Do not exceed maximum wheel load. Customer must compare OEM vehicle load rating to maximum wheel load rating. Do not overinflate. Refer to tire manufacturer's recommendation for proper tire pressure.
Before mounting the tire, perform a wheel fitment check to ensure proper clearance from any obstructions. Valve hole is on the inside unless noted otherwise.
1 Capacity ratings as dual or single in highway service — bias-ply or radial. Load ratings in lbs. for items 39 through 50 rounded to nearest multiple of 5.
2
Some wheels may bear part numbers not shown in this manual. Before servicing these wheels, contact your Alcoa wheel representative for proper load, inflation and part compatibility information.
3
Outset (positive)/inset (negative) — The distance from the rim centerline to the mounting face of wheel. Inset (negative) places the rim centerline inboard of the wheel mounting face
and outset (positive) places the rim centerline outboard of the wheel mounting face (½ dual spacing = offset).
4
These wheels must be installed only in the inset position because spherical ball seats are on only one side of the disc.
* Part numbers should end in “1” or “9” when used in an inset position and “0” or “2” when used in an outset position.
** Disc Brake Compliant — As of January 2005: 883640 replaces 883620 and 884620, 983640 replaces 983620; As of March 2005: 883440 replaces 883420, 893640 replaces 893600, 823640 replaces 823660A, 833640 replaces
833660A
† Indicates European New Generation Wheels. †† Check with vehicle manufacturer or axle manufacturer before retrofitting to outset wide base wheels to insure compatibility with axle and wheel end components. P/Ns 841100, 841400,
841600 and 841610 are recommended for use on drive axle and trailer axle positions, but with some restrictions on “N” trailer spindles.
‡
Hub cover system kits P/N 076085 (front) and P/N 077085 (rear) contain screw-on Hug-a-lug
®
nut covers and require a minimum of four threads of the stud to extend above the tightened cap nut for use.
‡‡
The minimum stud standout required for P/N 833580 is 2.375 inches (60.3mm) when using wheel nut P/N 39874. Taller nuts will require more stud standout. P/N 833570 will be phased out 1st quarter 2005 and will be replaced by the
higher load rated 833580.
§
P/Ns 885600 and 985600 are Alcoa Severe Service Wheels.

for aluminum wheels for trucks, trailers and buses, call toll-free 800-242-9898, option 1. To view online, go to
www.alcoawheels.com. The Spec Data brochure contains current part number availability and complete specifications
such as wheel dimensions, load rating, wheel weight, outset and inset, inflation pressure and accessory part numbers.
Alcoa provides training, live or on video, on proper wheel installation and maintenance practices free of charge.
Contact Alcoa Wheel and Forged Products at 1-800-242-9898, option 4.
Note: Dura-Bright ® wheels produced after November 2002 have Alcoa wheel part numbers ending with “DB”
(earlier wheels have part numbers ending in a 4 or 7) with bead seat diameters measured in 0.5-inch increments.
Not all Alcoa wheels are available with the Dura-Bright
® surface treatment.
Note: The Dura-Bright ® surface treatment and the Dura-Flange ® options are not currently available together on the same
wheel. Dura-Bright ® and Dura-Flange ® are available in all polished finishes.
