True or False. Over inflation of a tire causes excessive wear on the outer edges of the tread.

True or False. Tires and wheels must be balanced statically and dynamically.

True or False. When checking air pressure, always refer to the tire sidewall, because this is the most accurate air pressure reading.

True or False. When a radial tire bulges on the sidewall, this means that the tire is underinflated all the time.
