While discussing run-flat tires: technician a says that some are self-sealing tires and are designed to quickly and permanently seal sidewall area punctures. technician b says that most of these tires have reinforced sidewalls that are able to support the vehicle at any speed without air in the tire. who is correct?

a. technician a
b. technician b
c. both a and b
d. neither a nor b

The correct option is d ( Neither A nor B)

Explanation:

Technician A made 2 mistakes in his statement.Firstly the tire is self supporting not self sealing.

Secondly, this tire does not provide permanent sealing of punctured area option a is incorrect.

This self-supporting tire after being affected with complete air leakage can temporarily bear the load of the car and avoid rolling over a distance of 80 km at a maximum speed of 55 mph. Here is what technician B suggested incorrectly as the tire after being.Here the technician B suggested incorrectly as the tire after being affected with puncture can not travel at any speed so option B is wrong

Since option a and b are incorrect and c is invalid.
