• No-flat

• Run-flat

• All-season

All of the following are correct about space-saver spare tires, EXCEPT:

• they can be run up to 500 miles before the regular tire is fixed and installed.

• they can be run at speeds up to 50 mph maximum.

• they may come with a charged canister for inflation.

• due to their small size, they may have inflation pressures much higher than normal tires.

Because of the extra materials used in the construction of run-flat tires, they are less expensive to purchase.

• True

• False

Space-saver spare tires normally require a specially charged canister for inflation when being installed.

• True

• False

• Technician B

• Both Technician A and Technician B

Which of the following is true?

• Modern tires are built with single ply or cord under the tread.

• Tire sidewalls are a special type of tire with tread.

There are three different wheel offsets: zero offset, positive offset, and negative offset. Technician A says that negative offset places the hub mounting closer to the brake side of the wheel. Technician B says that negative offset is farther away from the brake side of the wheel. Who is correct?

• Tech A

• Tech B

• Both Techs A and B

• Neither Tech A nor Tech B

Technician A says tire with a speed rating of Z has the highest possible speed rating. Technician B says that tires with Z-speed ratings allow drivers to legally exceed posted maximum speed limits. Who is correct?

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither Technician A nor Technician B

________ lug nuts have a tapered end that is placed toward the rim and that taper fits into a matching taper in the rim to help center the wheel on the lug studs.
