There are lots of things to consider when investing in a tire changer. Once specific needs have been assessed, towing company Tacoma it is important to not only review the overall quality of the changer but also its parts. This complete evaluation is tremendously important for the overall life and proper function of the tire changer.
It is important that the cabinet is built with thick enough steel, welds, and a quality design to ensure the that, over time, it will continue to operate as it did when it was purchased. If the cabinet weakens (as in lower quality models) it cannot support the turntable correctly or the vertical arm and down “hex” shaft.
As wheels progressively keep getting larger over time, those products that use poorly-built vertical arms and lower quality hex shafts responsible for working the tire and rim on the machine’s turntable are exposed as inferior. Those made of inexpensive steel or with loose fitting hex shafts will bend and fail.
The “duckhead,” or mounting head, needs to be made of high-quality, heat-treated steel that won’t deform. Mounting heads made of cheaper material bend and deform and will damage wheels, which can be very costly, not to mention unprofessional.
Consider the bead breaker, – tire changers made with stainless steel tanks, and chromium plating, for example, ensure years of use and the best protection against the “enemy” – moisture and water from an air system. Some others use inexpensive material to build the tank for the bead breaker and in a short time these fail because of rust and seal problems.
Turntables that are built with much thicker steel and use high quality bearings are a great feature, due to larger wheels common today. Large wheels require a certain level of strength to handle them. The turntable and clamps that hold a wheel in place while tire changing must be strong enough to resist bending or slipping. Built correctly, a turntable and clamps grip a wheel with even pressure at all 4 clamps. “Cheap” tire changers are subject to uneven grip, and thus, wheels jumping off turntable clamps. The linkage under the turntable is very important, as it moves the clamps in and out and holds the gripping position. Many inferior designs leave just 2 or 3 clamps holding the wheel or rim instead of 4, creating frustration when attempting to change tires.
Design and proper materials allow the turntable on PRO series tire changers to run “true”. It is concentric and rotates parallel to its mount. Run out on poorly-built machines can be 2-3 mm, enough to damage a wheel.
