Suspension and Steering Systems Latest Questions
and Answers 100% Correct
Aspect ratio
the 65 in P215/65 R15 89H indicates blank or profile (serios) of the tire. Is the relationship of its
cross-sectional height (from tread to bead) to its cross
Bead
is the portion of the tire that helps keep it in contact with the rim of the wheel. It also provides
the air seal on tubeless tires-sectional width (from sidewall to sidewall).
Belted bias ply
tire similar to bias ply tires, except that two or more belts run the circumference of the tire under
the tread.
Bias ply
tires have fabric plies that run alternatively and form a crisscross design. The angle varies from
30 to 38 degress with the centerline of the tire.
Drop center
area designed to allow for easy tire removal and installation.
Dynamic Balance
is the equal distribution of weight on each side of the centerline.
Hub
the wheel is bolted to it.
,Lateral runout
Tire that wobbles side to side.
Plies
the cord body or casing consists of layers of rubber-impregnated cords, called
Radial ply
tires have body cords that extend from bead at an angle of about 90 degrees or "radial" to the
circumferential centerline of the tire plus two or more layers of relatively inflexible belts under
the tread.
Radial runout
A tire that is off center and also called eccentricity.
sidewall
are the sides of he tire's body. Are constructed of thinner material than the tread to offer greater
flexibility.
Static balance
is the equal distribution of weight around the wheel.
Tire pressure monitoring system
The monitoring systems must illuminate a warning light if one or more tires is at least 25 percent
below the recommended cold-inflation pressure to warn the driver of an under-inflated tire.
Tread
, or crown, is the portion of the tire that comes in contact with the road surface.
Uniform Tire Quality Grading (UTQG)
(UTQG) a rating system developed by the DOT. This rating is comprised of three factors: tread
wear, traction, and temperature resistance. All tires have these ratings besides snow tires.
Wheel Offset
is the vertical distance between the centerline of the rim and the mounting face of the wheel.
Wheel Shimmy
wheels that are dynamically unbalanced can cause blank.
Wheel tramp
wheels that are statically unbalanced cause a bouncing action. Causes uneven tire wear.
Wheels
are made up of either stamped or pressed steel discs riveted or welded into a circular shape or are
die-cast or forged aluminum or magnesium rims.
Primary Purpose of tires
is to provide traction they are also designed to carry the weight of the vehicle, to withstand side
thrust over varying speeds and conditions, to transfer braking and driving torque to the road, and
to absorb much of the rock shock from surface irregularities.
