What is the purpose of tire cages?

A tire cage is an essential piece of equipment designed to keep tire mechanics safe when inflating a tire. However, not all tires require a tire inflation cage. These cages are designed to service multi-piece and single-piece rim wheels.

What are tire cages used to prevent?

Permanently mounting an inflation cage to the floor or near a wall prohibits deformation of the bottom plate and prevents equal dissipation of energy released in the event of a tire explosion.

Should a tire cage be bolted to the floor?

All tire inflation cages must be free-standing and never anchored to a floor, or even a portable surface. This is for good reason. During a catastrophic lock ring failure, the separated lock ring and the wheel strike the opposing inside walls of the cage with the same amount of force.

Do you need to use tire cage guard upon tire inflation?

OSHA requires the use of a restraining device for inflating tires on multi-piece rims. Safety cages provide the kind of restraint needed to safely contain possible explosions and the dangerous aftereffects from it.

Why do tires explode when inflating?

“A tire under pressure is almost like a bomb. There’s a lot of pressure there, and when it’s released, it can be a big explosion,” Branick CEO Tom Bolgrean said.

What does Rist stand for?

Proper wheel installation involves a short checklist of items, which the Tire Industry Association refers to in its Automotive Tire Service training program by the acronym RIST, which stands for Remove, Inspect, Snug and Torque.

What is the max tire pressure?

between 44 and 51 PSI
According to Berger the maximum inflation pressure for modern tires is typically between 44 and 51 PSI (pounds per square inch). If a driver inadvertently puts too much air in a tire it won’t necessarily cause any damage, but it will impact other aspects of the vehicle.

When should tire restraining devices be inspected?

1910.177(d)(3)(iii): Restraining devices and barriers shall be visually inspected prior to each day’s use and after any separation of the rim wheel components or sudden Page 15 release of contained air.

Do all tire inflation devices must include a clip on air chuck?

(a) Tire inflation shall be accomplished by means of a clip-on chuck with a minimum 24-inch length hose to an in-line foot or hand valve and gauge. A clip-on chuck and an in-line regulator (factory preset at 40 psi maximum for passenger car tires or a restraining device may be used as an equivalent.

How old can tires be and still be sold?

If you trust the dealer and have informed yourself about the situation, then stale tires may be OK. But the dealer should always inform the buyer before putting them on the car. Tires have a lifespan of five to seven years from date of manufacture, even if they are never used.
