All of the following issues may be caused by tire problems except _____.

Automotive tire tread depth that measures less than about _____ is considered worn and requires tire replacement based on safety guidelines.

True or False? Underinflation causes the center area of the tire’s tread to expand outward and wear before the outer corners.

Tire sidewalls can bulge outward and form an air bubble in the sidewall due to _____.

A vehicle’s weight pressing down on _____ produces noticeable humming or growling sounds.

True or False? The purpose of performing a tire rotation on a vehicle is to help even out tire tread wear and extend tire service life.

The phrase pack the bearings means to _____ the wheel bearings.

Overtorquing lug nuts can cause wheel or hub distortion, vibration, and excessive _____.

Technician A says tire impact damage cannot occur when the vehicle is traveling at highway speeds. Technician B says often even minor tire damage, cuts, air bubbles, and tread wear patterns require tire replacement to ensure safe driving characteristics. Who is right?

Technician A says torquing lug nuts correctly means tightening them in a crisscross pattern. Technician B says overtorquing lug nuts is beneficial and recommended on vehicles equipped with aluminum wheels and lightweight hubs. Who is right?

Identify the type of wheel bearing.

Identify the type of wheel bearing. Goes usually on FWD Vehicle.

Identify the type of component!!!!!

Identify the type of wheel bearing.

Identify the type of wheel bearing.

Technician A says today’s automotive tires use a system of two conjoined inner tubes to hold air pressure and prevent leaks. Technician B says one of the functions of an automotive tire is to provide adequate traction with the road surface. Who is correct?

Technician A says an automotive tire’s belts stretch horizontally across the beads to form the carcass, or body, of the tire. Technician B says an automotive tire’s liner provides a leakproof membrane for tubeless tires. Who is correct?

Technician A says a radial ply tire’s belts are sometimes made of steel. Technician B says a radial ply tire’s belts are sometimes made of fiberglass. Who is correct?

Technician A says tire markings on the sidewall of a tire give information about a tire’s load-carrying ability. Technician B says tire markings on the sidewall of a tire provide the tire’s speed rating. Who is correct?

A tire size measurement given in the P-metric size designation is listed as: P235/50 R18. Technician A says the number 50 is the aspect ratio, which measures the tire’s weight at 50% of the tire’s cross-sectional width. Technician B says the number 18 signifies the tire’s year of manufacture in the 21st century, which is 2018. Who is correct?

Tire grades and tire markings are being discussed. Technician A says tire tread wear, tire traction, and tire temperature resistance ratings are all part of the Uniform Tire Quality Grading System. Technician B says a tire’s load index is listed as a letter from B to Y on the tire sidewall that correlates to a weight-carrying capacity range of between 1,000–1,500lb (456–680 kg). Who is correct?

Technician A says vehicle manufacturers instruct owners to drive on a compact spare tire in the exact manner as they would drive on a traditional full-size automotive tire. Technician B says run-flat tires are constructed with wear bars that serve as a supplementary protective layer over the tire tread. Who is correct?

Tire pressure monitoring systems (TPMS) are being discussed. Technician A says a TPMS is installed only in commercially used vans and trucks in the United States. Technician B says some TPMS give the air pressure reading for each tire on the dash display. Who is correct?

Technician A says on passenger vehicles, the center wheel section of a drop-center wheel has a smaller diameter than the rim to ease tire installation and removal. Technician B says the majority of automotive wheels are made of aluminum. Who is correct?

Technician A says that depending on the vehicle manufacturer, lug nuts are manufactured with both right-hand threads (turn clockwise to tighten) or left-hand threads (turn counterclockwise to tighten). Technician B says lug bolts are press-fit into the hub or axle flange and can only be removed with manufacturer-specific tools. Who is correct?

Wheel weights are being discussed. Technician A says wheel weights are thin metal strips that are pressed into the grooves of a rubber tire tread to offset tread height manufacturing inconsistencies. Technician B says wheel manufacturers recommend using a hammer to apply clip-on lead weights to an aluminum wheel. Who is correct?

Technician A says wheel bearings in several vehicle models are the tapered roller bearing type. Technician B says wheel bearings in certain vehicle models are the ball bearing type. Who is correct?

The basic parts of an automotive wheel bearing are being discussed. Technician A says a wheel bearing’s outer race is sometimes pressed into the automobile’s steering knuckle. Technician B says the bearing’s outer race is sometimes pressed into the hub. Who is correct?

Technician A says a steering knuckle is a basic component in a driving hub and wheel bearing assembly. Technician B says the inner stub shaft is a basic component in a driving hub and wheel bearing assembly. Who is correct?

Technician A says an automotive tire’s beads are used to stiffen the tire treads. Technician B says an automotive tire’s beads are used to hold the tire’s sidewalls against the wheel rim. Who is correct?
