Floor anchor bolts need to be periodically checked for looseness on two-posts above ground lifts.

A lift point reference guide should be used everytime a vehicle is raised on the lift.

What is the minimum measurement of the mountain and snowflake symbol used to designate a tire for severe winter use?

Every tire must be removed from the wheel for inspection and repair.

The MIL will notify the driver that one or more of their tires are underinflated by 25%

All clamp-in sensors use the same grommets.

The torx bolt on snap-in sensors does not have a torque

If any area of tread depth is worn to 2/32”, then the tire must be replaced.

Feather edge wear can be caused by a bent vehicle frame.

A nail hole repair has no effect on the condition of the tires tread.

Hearing protection is recommended when you have to raise your voice to talk to someone who is an arm's length away.

Approximately 12% of all workplace injuries are slip and fall accidents.

When lifting a heavy load, its important to hold your breath.

Tires with a 16.5-inch bead diameter have a 15-degree bead taper.

When replace tires on a vehicle, technicians should ignore the placard when selecting the replacement size.

Bias ply tires have casing plies that run between the beads at an angle.

Directional tires must be installed with the arrows pointing in the direction of the tire's rotation.

Radial tires must have the word "radial" molded into the sidewall.

It is acceptable to rotate tires in any pattern, regardless of vehicle type of the condition of the tires.

Larger tires can affect speedometer and odometer accuracy.

On AWD vehicles, all four tires must be marked with the same size.

Rim diameter is usually measured in millimeters.

Wheel lug nuts are the same so they can be interchanged.

Bolt patterns on 6-lug and 8-lug wheels are measured from the center of one bolt hole to the center of the opposite bolt hole.

On a wheel with zero offset, the mount surface of the wheel is on the centerline of the rim.

A brief walk-around inspection should be performed so that any damage can be noted before the vehicle is lifted.

Backspace is always measured in millimeters and reflects the distance from the mounting surface to the back edge of the rim.

Lug nuts and lug bolts do not need to be inspected.

If the mating surfaces are not cleaned prior to installation, then the installation torque will be lower.

Lubricant has no effect on fastener torque and clamping force.

Proper torque ensures that the assembly will stay on the vehicle.

It is acceptable to repair bead leaks with innerliner sealer.

Toque is the measurement of twisting force and is reflected in foot-pounds or newton-pounds.

When stitching a repair unit, technicians should start in the center and work to the outside to eliminate any trapped air.

Store lug-nuts together, on the shop floor, and away from the vehicle, so they do not roll under the vehicle service.

Once a speed-rated tire is repaired, the speed rating is no longer valid.

Chrome sockets can be used with impact wrenches, as long as the wrench is set to its lowest setting.

Plugs installed from the outside of the tire are not acceptable.

It is acceptable to use a steel hammer to remove a stuck wheel.

Cleaning the inner liner before repairing the tire is not important.

Rim-clamp tire machines secure steel wheels from the inside.

Nail hole repairs in the shoulder area require special repair units.

Dynamic balance can correct the amount of hop and wheel shimmy, or wobble.

The beads should be seated with the valve core removed.

Lateral run-out refers to the amount of variation that occurs in the vertical plane as a tire rotates.

When unseating the beads, it is recommended to treat every assembly like it has a TPMS sensor to avoid damaging a valve stem or band-mounted sensor.

Valve stems do not need to be replaced.

Concentric seating has no effect on tire balancing.

If the air pressure is 80% of the operating pressure in a tire with all steel construction, then it must be completely deflated before removing the assembly from the vehicle.

If a computerized balancer "zeros out", the vehicle will not experience a vibration.

Sensor position is not important during the tire demounting process.

Cosmetic lug caps will break off when loosened with an impact wrench.

Technician A says the inflation pressure imprinted on the sidewall is the recommended pressure for the vehicle. Technician B says the load rating on the sidewall is the maximum load for the tire when inflated to the maximum inflation pressure.

Technician A says rocks imbedded in the treat should be removed before balancing a tire and wheel assembly. Technician B says when installing wheel weights on a rim flange of an alloy wheel, it is acceptable to use any type of coasted wheel weight.

Technician A says brake cleaner can be sprayed on the inside of a wheel to clean dirt and debris before applying adhesive wheel weights. Technician B says wheels cannot be dynamically balanced when using adhesive wheel weights.

Technician A says the mounting process on a clamp-in sensor should always begin with the valve stem located under the demount/mount head. Technician B says the maximum inflation pressure to seat the beads is 20 psi.

Technician A says that when replacing on tire, the best tire should be positioned at the right front of the vehicle. Technician B says that when replacing two tires, the new tires should be placed on the drive axles.
