6-6 Wheels and Tires/Central Tire Inflation System (CTIS)
WARNING: Never use wheel assemblies with wheel
half studs that are damaged, loose, or have stripped
threads. Damaged studs can cause improper assembly
which could cause individual fasteners to fail. Any of
these situations could cause serious injury or death.
NOTE: When replacing a damaged wheel half stud, also re-
place two adjacent studs.
12. Inspect inner rim half for cracked, broken, rusted, pitted,
bent, loose, or stripped studs. Replace damaged studs
along with two adjacent studs . Failure to do so may
result in equipment damage, personal injury or death.
13. Inspect valve core for cracks or deterioration. Replace
valve core if damaged (Figure 6-8).
14. Inspect core housing for cracks or deterioration. Replace if
damaged.
15. Inspect insert and cap for damage. Replace if damaged.
Repair
1. If studs are damaged, drive studs out of inner rim half.
Discard studs (Figure 6-9).
2. Align splines on studs with splines in inner rim half and

Assembly
WARNING: Never use tubes in the two-piece take-
apart wheel assemblies. Use of a tube defeats built-in
safety features of the wheel, and could cause the wheel
to come apart under pressure, resulting in serious in-
jury or death. Use only replacement parts specified in
parts manual. Wheels assembled with components
which do not meet specifications could cause the assem-
bly to separate under pressure, resulting in serious in-
jury or death. To avoid injury ensure runflat
compressor strap is centered on runflat.
1. Apply one 11-ounce tube of gel lubricant around inside of
tire at crown area. Using clean brush, evenly spread gel
lubricant 4 to 5 inches wide on tire crown area (Figure 6-10).
