The Steps in Changing a Tire
Changing a Tire consists of multiple steps:
1.
Place the Wheel on the Turntable
. Use the Tire Lift and the Up Foot Pedal to get a Wheel
onto the Turntable.
2. Secure the Wheel . It is important for the Wheel to stay in place on the Turntable. Use the
Quick-Nut to do this.
⚠
DANGER It is extremely important to carefully secure every Wheel you work on. When
pressurized Tires fail, they can literally explode. The better the Wheel is secured,
the better off everyone in your garage will be if a pressurized Tire fails. Note that
even if you carefully secure the Wheel with the Quick-Nut, you must still take
precautions (described throughout this manual) with pressurized Tires. The
Quick-Nut can control the Wheel, in most cases, but cannot control what
happens to the Tire portion if it were to explode. Bystanders can be seriously
injured or even killed if a pressurized Tire explodes.
3.
Deflate the Tire
. There is a lot of energy stored in a Tire when it is inflated. You
must
fully
deflate the Tire before you can change it. If you do not, that energy will be released when you try to
change it, which could result in the Tire exploding, causing injury and even death to the Operator
or bystanders.
Never work on a Tire unless you have personally confirmed that it is
fully deflated . The best way to do this is to make sure the Valve Core has been removed from
the Body of the Valve Stem.
4. Break the Bead . Tires stay in position because the Tire Bead is correctly seated between the
Bead Retainer and the Rim Lip of the Wheel (called the Bead Seat). To change a Tire, you must get
the Tire Bead out of the Bead Seat all the way around both sides of the Tire. This is called breaking
the Bead.
5.
Demount the Tire
. Once the Bead is broken, you still have to slide the Tire over the Rim Lip of
the Wheel to get it fully off. Once the Tire is demounted from the Wheel, you can move it out of the
way and then put on the new Tire.
6. Mount the new Tire . Mounting a Tire is basically the opposite of the steps described above.
You first need to get the Tire over the Wheel (the opposite of demounting the Tire), then get the
Bead into position in the Bead Seat (the opposite of breaking the Bead), and then inflate the Tire
(the opposite of deflating the Tire).
7.
Inflate the Tire: Bead Seal, Bead Seat, Inflate
. The Tire inflation process consists of three
stages that could easily be considered a single process. Bead Sealing is putting in a small
amount of air pressure to push the Tire up against the Rim so that air does not leak out. Bead
Seating is putting in more air pressure to “pop” the Tire Beads into position in the Bead Seat.
Inflation is adding air pressure to the Tire manufacturer’s recommended pressure after the Bead
has been seated.
8. Remove the Wheel from the Turntable . Remove the Quick-Nut, slide the Wheel onto the
Tire Lift, and then use the Down Foot Pedal to lower it down to the ground.
