How to Mount an Auto Tubeless Tire
Mounting a tubeless automotive tire is not as difficult as it may seem. Today's technology has ensured that the proper tools and equipment have been developed to assist with tire mounting. With a little practice and some mechanical ability, tire installation is a breeze.

Make sure that you have installed a new valve stem into the wheel before mounting the tire. At the top of every wheel there is a machined hole that is for the installation of a new valve stem. Vehicles equipped with Tire Pressure Monitoring Systems usually have a steel bolt in type valve stem. Those valve stems do not require replacement.
With a new tire in hand, lube both sides of the tire bead, and position the bottom bead between the head attached to the tire machines arm, activate the machine's rotation pedal with your foot, and allow the tire to rotate 360 degrees until the bottom bead is mounted. The same step applies for the top bead.

Inflate the tire with air to seat the beads. Attach the machine's air hose to the valve stem, and with both arms, grab the tire in the center and pull up slightly. Apply heavy pressure to the inflation pedal with your foot. A high rate of air pressure will enter between the wheel and tire, allowing the tire to inflate. Remove the valve core first with a valve core tool. This often makes tire inflation easier because without the valve core, air can enter at a faster rate.

Remove the air hose from the valve stem, reinstall the valve core, and adjust tire pressure to proper psi. Make sure to balance the tire and wheel assembly.

Tips & Warnings
The components of a tire machine consist of a bead breaker, rim clamp, turntable, tower arm and mounting head. The machine is powered by both electricity and compressed air. The machine's actions are controlled by foot pedals, and each pedal controls a different function of the machine.
Most of today's new vehicles are equipped with TPMS sensors, (Tire Pressure Monitoring Systems.) When mounting and dismounting tires from their wheels, use caution when applying the tire machine's functions so that the arm or the bead breaker of the machine does not contact the sensor. The sensors are very sensitive and can break easily.
