SECTION III: SAFETY PROCEDURES FOR SERVICING TRUCK TIRES AND RIMS/WHEELS The following guidelines are very important safety procedures. WARNING: Do not add air to tire and rim assemblies that have been operated in a seriously underinflated or flat condition. Unseen damage could cause the assembly to explode during removal if the tire is removed while still inflated. You may not be able to tell if only one tire is flat or underinflated. ◆ Always deflate. beginning on page 26. even fatal. Adding air to such an assembly can cause it to separate explosively. ◆ Run a piece of heavy wire through the valve stem to make sure stem is not plugged. accidents for you or others. If you service truck tires and rims/wheels.177. DEFLATE TIRES BEFORE SERVICING ◆ Always deflate the tire completely before removing from vehicle (deflate both tires of a dual assembly). remove from the vehicle. Note: For mounting and demounting steps for specific rim/wheel types see Section XI. "Eyeballing" the tire or "thumping" it does not tell you the pressure reading. 1. ◆ In dual assemblies use an air gauge and check the pressure in both tires. The tire can explode causing serious or fatal injury. 4 . UNDERSTAND. and inspect a tire and rim assembly that has been operated in a run-flat or underinflated condition (80% or less of recommended pressure). because the weight of the vehicle is carried by the other tire. Improper service procedures can lead to serious. ◆ Remove valve core to ensure the tire is deflated. Always use an air gauge to measure tire pressure. This is required by OSHA Standard 1910. disassemble.
III 2. The stamping is generally found on the rim near the valve slot. Even a small difference could cause an accident. ◆ Be sure your tire size is approved for your rim. ◆ Size and type stamping appears on every Accuride rim or side/lock ring. See page 3 to get free copies of these charts. Don't rely on eyeball estimates. Rims/Wheels can accommodate tires of varying widths. ◆ Don't stand in front of a tire/rim during deflation. do not use the parts. ◆ Rim components must not be interchanged except as provided for in the Multi-Piece Rim Matching Chart. Remember: Just because parts arrive together doesn't mean they belong together. WARNING: Mismatched tire and rim components may explode and cause serious injury or death. Be sure all parts of your assembly are correctly matched. Check the chart on page 25. 5 . If you cannot read the size or type stampings on any part. Such parts should be destroyed and discarded.

A DEMOUNTABLE RIM does not have a center disc and is clamped onto a cast spoke wheel. a rim is not a wheel and a wheel is not a rim. RIM The rim supports the tire. A MULTI- PIECE RIM is an assembly consisting of a base and either a side ring or a side and lock ring depending on the type. Remember. SECTION IV: CORRECT NAMES OF RIM/WHEEL COMPONENTS AND ATTACHING PARTS There is confusion over the terms "wheel" and "rim" in the industry. Tubeless Demountable Rim (single piece) Tube-Type Demountable Rim Assembly (multi-piece) shown in cross section DISC WHEELS A combination of a rim and a disc permanently attached to the rim and attached to the hub by studs and nuts. There are two types of rims: a single piece rim (tubeless—some 16 inch single piece rims are either tubeless or tube-type) and a multi-piece rim (tube-type). Please read the following definitions so you will understand the terms appearing in this manual. A SINGLE PIECE RIM is a continuous one-piece assembly. there is an important difference between a side ring and a lock ring. Tubeless Disc Wheel Tube-Type Disc Wheel Assembly 12 . Likewise.

torque requirements. For questions contact Accuride Field Engineering at 800.869.2275.
WARNING: Improper parts and incorrect installation procedures could cause a wheel to fail in service. A
serious, even fatal, accident could result. Follow all instructions for inspecting and installing rims/wheels. Do
not substitute parts. Remember:
➡ Rims must be mounted with the required clamps and studs. All clamps are not interchangeable.
➡ Nuts must be retorqued routinely. Use the proper nut torque and tightening sequence.
➡ Each tire, wheel, and axle has its own maximum rating. Do not load and inflate the tire/wheel/axle
system beyond the rating of the lowest rated component.
➡ Rims must be mounted on spoke wheels with proper contact surface.
INSPECTION AND PREPARATION INSTRUCTIONS
■ During Tire Inspections or Periodic Vehicle Maintenance Checks:
◆ Check all metal surfaces thoroughly including spacer bands and inboard side of rims. Watch for excessive rust or
corrosion buildup; cracks in metal; bent, broken flanges or components; loose, missing, or damaged nuts or clamps;
bent or stripped studs; and incorrectly matched rim parts. Correct any problem discovered. (See pages 20
through 22.)
◆ Replace an assembly that is damaged or has damaged components. Remember: Excessively corroded or cracked
rims are dangerous, especially during the removal of the assembly. Deflate tire (both tires of a dual assembly) before
removing the rim. Insert a wire through the valve to ensure that debris has not prevented deflation. (See page 4.)
◆ Replace broken studs and each unbroken stud next to the broken stud.
◆ Determine the cause of the damage before installing another rim. (See pages 20 through 23.)
◆ Inflate tires to only the recommended air pressure. Be sure not to exceed the wheel's maximum inflation rating. Use
precautions outlined in Section III, Safety Procedures.
■ During Tire Changes (See tire demounting procedures, Section XI):
◆ After the tire is removed, check all metal surfaces, especially the tire side of the rim and the rim 28° mounting
surface. Watch for the conditions outlined above.
◆ Replace damaged rims, rings, clamps, nuts, studs, and valves. Inspect and replace valve grommet as needed.
◆ Completely remove rust, dirt, and other foreign materials from all surfaces. It is especially important to clean
areas used for mounting the rim to the vehicle and the rim area where the tire seats. Use hand or electric wire
brushes, light sand blasting, or solvent baths to clean these areas. Rim mounting areas must be kept flat. Remove
any metal projections, burrs, or paint buildup from the mounting areas. The spoke wheel where the wheel contacts
must also be cleaned and kept flat. The rim bead seat must be clean and free of rust, corrosion, and rubber deposits
to ensure proper tire seating. The gutter of the rim and the rings must be clean to ensure proper seating of these
components. (See page 23.)
WARNING: After the tire/rim assembly has been deflated according to Section XI, loosen the nuts
approximately one revolution and verify that the clamps are free before continuing to remove the nuts and wheel
clamps. Clamps may become wedged during vehicle operation and may spring from the assembly becoming a
projectile if not removed properly.
■ During Tire Changes (continued)
◆ Paint or spray all bare metal surfaces of the rim and wheel using a fast-drying metal primer. Surfaces should be clean
and dry before painting. Ensure that bare metal areas on the tire side of rim are painted. This is especially important
for tubeless rims, since moisture in the air chamber can cause corrosion. The rim mounting areas must be kept free
of paint runs and paint buildup.
◆ Use the proper tire and rim combination. (See page 25.)
◆ Lubricate tire side of the rim base and tire beads just before mounting tire. Avoid the use of any lubricant or solvent
that is injurious to rubber, steel, or paint. A combination lubricant and rust-preventive compound is preferable.
(See page 8.) The air supply should incorporate moisture traps to prevent water or moisture inside the tire. Follow the
tire mounting instructions for type of rim being used. (See Section XI.)
■ Spacer Bands
◆ Check the spacer band for concentricity and proper width. Ensure that the spacer band has not been distorted or bent
in service or shipment.
◆ Replace damaged spacer bands and those with more than 1/8" width reduction.
Spoke Wheel Mounting
1. Inflate Tire Prior to Installing on Vehicle.
◆ See Inflation Procedure on pages 8 and 16. If multi-piece rim is difficult to install on cast spoke wheel, reduce
inflation to 80% of recommended inflation pressure. Following installation on cast spoke wheel, inflate to full
2. Inspect Parts Before Installing. (See page 53.)
◆ Check all parts for damage, including rims and rings. Ensure that studs, nuts, and 28° mounting surfaces of cast
spoke wheel are functional, clean, and free from grease. Clean cast spoke wheel with wire brush if scale is present.
The spacer band should be clean and free from distortion.
◆ Replace any damaged parts. Do not bend, weld, heat, or braze components. Do not use tubes to stop rim air
◆ Use correct nuts and clamps. Inspect nuts and clamps to ensure they are not worn.
3. Install Rim on Vehicle.
◆ Place the rim and inflated tire on cast spoke wheel. Note: All 8.5 - 5° rims require special size hubs and spacer
◆ Align valve locators between spokes. Secure clamps evenly in position. Snug up nuts in the sequence shown in
3 and 6 spoke 5 spoke
◆ Do not tighten nuts fully. After the nuts are properly seated and the rim is centered on the spoke wheel, tighten the
nuts one-quarter turn at a time in the criss-cross sequence until they are tightened to 200-260 ft.-lbs. (dry). This will
permit the rims to properly align themselves on the 28° mounting surfaces of the cast spoke wheel.
