A tire changer is one of the hardest-working machines in any tire shop or auto repair facility. Choosing the right one means matching the machine’s capabilities to your daily volume, the types of tires you handle, and your budget. MTF Equipment has been selling and servicing tire changers in Houston since 1977 — here’s what we’ve learned about helping shops make the right choice.
Rim Clamp vs. Leverless Tire Changers
Rim clamp tire changers like the COATS Maxx 90 and Maxx 80 hold the wheel from the outside or inside using adjustable clamps on the turntable. They’re the most common type for standard passenger and light truck tires. Rim clamp machines are reliable, relatively affordable, and straightforward to operate. For most tire shops and general repair facilities, a quality rim clamp changer handles the majority of your daily work.
Leverless (touchless) tire changers use rollers instead of a traditional mount/demount head, eliminating metal-to-wheel contact during the mounting process. These machines are designed for shops handling expensive custom wheels, low-profile performance tires, and run-flat tires where rim damage is a serious liability. They cost more than rim clamp machines but pay for themselves quickly if you’re regularly handling high-end wheels.
Key Features to Consider
Power Assist
Modern tire changers offer pneumatic or hydraulic power-assist features that help with stubborn beads, stiff sidewalls, and low-profile tires. The COATS Maxx 90, for example, includes a power-assist tower that significantly reduces the physical effort needed for difficult tires. If your shop handles any volume of low-profile or run-flat tires, power assist is worth the investment.
Bead Breaker
The bead breaker is what separates the tire from the rim before demounting. Look for a machine with a strong, smooth bead breaker that handles both passenger and light truck tires without damaging rims. Tabletop bead breakers (integrated into the turntable area) are convenient for high-volume shops. Side-mounted bead breakers work well for standard volume.
Wheel Capacity
Consider the maximum wheel diameter and width your machine needs to handle. Standard rim clamp changers handle up to 24 to 28-inch wheels. If your shop services lifted trucks, custom SUVs, or specialty vehicles, make sure your changer can accommodate larger sizes.
Wheel Protection
Every tire changer should include plastic jaw covers, nylon protectors, or similar features to prevent metal-to-wheel contact. For shops handling alloy and custom wheels, this is non-negotiable. Higher-end machines include additional protection features like plastic-coated mount heads and adjustable clamping pressure.
Matching Volume to Machine
Be realistic about your daily tire volume when selecting a machine. A shop mounting 10 to 20 tires per day works fine with a solid mid-range machine like the COATS Maxx 80. High-volume tire shops doing 40+ tires per day need a heavy-duty machine with power assist, a fast turntable, and robust construction that holds up under continuous use — the COATS Maxx 90 is built for this workload. Overbuying wastes capital; underbuying leads to slow production and premature machine wear.
