The tire and the flanges that constitute the liquid chamber are held together by two
stainless steel rings. One of the two rings contains captive screws. This ring fixes the
flange with the valves to the tire. The captive retaining screws of this ring are accessed
from the inside of the acoustic wheel (see Figure 6-23 on page 97).

Before changing the tire, make sure that the inside and outside surfaces of the new tire
are clean. Even dust, minute particles, stains, or deposits present on the surfaces can
generate acoustic interference. The tire’s surfaces can be cleaned using mild soap and
a soft cloth. For more information, see “Cleaning the Liquid Chamber” on page 85.
To change the tire
1. Remove the four external retaining screws on the acoustic wheel’s plain flange
(see Figure 6-24 on page 98).
When removing the screws from the plain flange, take care not to lose the screw
gaskets.
