Are you paying proper respect to pressure?

It’s no secret that proper inflation pressure is the key to truck tire life and performance. When tires are overinflated, any gains in decreased rolling resistance are offset by accelerated tread wear. On the other hand, when tires are...

OSHA Compliance

Of course, none of this matters if technicians use an OSHA-compliant tire inflation system.

Federal law requires that three components must be in place for every tire inflation system. There must be a clip-on air chuck so the technician doesn’t have to stand next to the valve stem.

There must also be a sufficient length of hose so the employee can stand outside the trajectory of both sidewalls.

Additionally, tire inflation systems must have an in-line valve with a pressure gauge or a presetable regulator, both of which prevent accidental overinflation.

It doesn’t matter who is doing the tire inflating or the location of the inflation. When a truck tire is being inflated, the three aforementioned components must be in place.

Technically, the restraining device is only required for multi-piece assemblies, as OSHA allows tires on single-piece rims to be inflated on the vehicle if the lug nuts are fully tightened. But, every tire manufacturer and industry organization, including TIA, recommends using a restraining device when inflating any type of truck tire.

You rarely hear about inflation-related accidents when the assembly was in the restraining device. Yet most of the horror stories start with a safety cage still in the bed of the truck or in a corner of the shop.

If your fleet is inflating truck tires in any way, there are OSHA regulations and other industry recommended practices that apply.

Compliance Training

TIA’s Fleet Tire Service OSHA Compliance Training Program outlines all of the federal requirements for an inflation system and includes the step-by-step inflation and inspection procedures to identify zipper ruptures or disc wheels damaged by heat.

The program’s video also demonstrates the consequences of standing inside the trajectory of the sidewall should a zipper rupture occur.

The Tire Industry Association (TIA) is an international association representing all segments of the tire industry, including those that manufacture, repair, recycle, sell, service or use new or retreaded tires, and also those suppliers or individuals who furnish equipment, material or services to the industry. TIA was formed by the July 2002 merger of the International Tire & Rubber Association (ITRA) and the Tire Association of North America (TANA). TIA’s main office is in Bowie, MD. The association has more than 6,000 current members.
