a) the tires
b) air in the tires
c) vehicle suspension system
2. Tires are designed to:
a) transmit steering forces (true / false)
b) transmit braking forces (true / false)
c) transmit driving force (true / false)
d) transmit road feel (true / false)
e) support the load (true / false)
3. When a vehicle is let down off a
jack changing the shape of the tire, the volume of air in
the tire:
a) increases
b) decreases
c) remains the same
4. In the above
situation, the inflation pressure of the tire:
a) increases
b) decreases
c) remains the same
5. At 55 mph
a passenger car tire turns approximately:
a) 225
b) 450
c) 600
d) 800
revolutions per minute
6. At 55mph
a truck tire turns approximately:
a) 225
b) 450
c) 600
d) 800
revolutions per minute
7. When a tire
is underinflated for the load being carried, the amount of
sidewall flexing:
a) increases
b) decreases
c) doesn't change
8. A tire with
too much air pressure has a soft sloppy road feel and a tendency
to skid in turns. On the other hand, a tire with too little
air pressure provides a rough ride, is more vulnerable to
shock damage and cutting and reduces its shock absorbing characteristics.
a) true
b) false
9. The tire
and vehicle manufacturers provide recommendations for the
right pressure for different loads and operating conditions.
This is found on:
a) label on your car or truck
b) molded on the tire sidewall
c) both of the above
10. The Tire
Safety Council and the Car Care Council estimates that proper
tire inflation will save over:
a) 400,000 gallons of gasoline everyday
b) 2 million gallons of gasoline everyday
c) 4 million gallons of gasoline everyday
d) 10 million gallons of gasoline everyday
11. A passenger
car tire in top condition can lose up to:
a) ½ pound of pressure per month
b) 1 pound of pressure per month
c) 2 pounds of pressure per month
a) 5 pounds of pressure per month
12. A truck
tire in top condition can lose up to:
a) ½ pound of pressure per month
b) 1 pound of pressure per month
c) 2 pounds of pressure per month
d) 5 pounds of pressure per month
13. The main cause of small air
losses in a tire wheel assembly in good condition is:
a) seepage between the bead and the wheel
b) seepage out the valve core
c) lack of a valve cap
d) air permeating the rubber of the tire
14. Inflation
pressure should be checked when the tire is:
a) hot
b) cold
c) doesn't matter
15. The recommended
frequency of inflation pressure checks using a quality gauge
is:
a) daily
b) weekly
c) monthly
d) annually
16. A "hot"
tire requires:
a) 30 minutes to cool down after you stop traveling
b) 1 hour to cool down after you stop traveling
c) 3-4 hours to cool down after you stop traveling
d) 8-12 hours to cool down after you stop traveling
17. On vehicles
equipped with "dual" tires, it is most important
to check:
a) outer dual only
b) inner dual only
c) both tires
18. With the
correct inflation pressure for the load one can expect to:
a) save fuel true false
b) optimize traction true false
c) optimize handling true false
d) increase tire mileage true false
