TC289DAA Dual-Assist-Arm Tire Changer + WB11 Balancer Combo
Stiff sidewalls fight back. Low-profile performance tires, run-flats, and reinforced light-truck tires all want to fold the upper bead back over the rim flange as the table turns — and on a single-arm changer, the operator ends up wrestling the tire with a pry bar instead of running the cycle. Adding both a left-hand and right-hand assist arm changes how the bay handles those tires.
This combo pairs the Atlas TC289DAA rim-clamp swing-arm tire changer (with both LH and RH assist arms) and the Atlas WB11 computerized spin balancer. The TC289DAA external-clamps from 11 7/8" to 27 7/8" with 5,500 lb of bead breaker force, and the WB11 balances cars and light trucks to 1-gram accuracy across a 10"–32" rim range.

Why Both Assist Arms Matter
A single right-hand assist arm holds the upper bead at the 3 o'clock position as the table turns. That works on most passenger tires, but on stiff sidewalls — especially low-profile and run-flat tires — the bead wants to lift back out of the well on the opposite side as soon as the head clears past it. The left-hand arm holds the bead at the 9 o'clock position simultaneously, keeping both sides of the upper bead seated in the well throughout the cycle.
The result is fewer scratched alloys, less operator wrestling with the bar, and faster cycles on the wheels that traditionally slow a single-arm bay down. For shops that see a high mix of custom rims and high-end tires, dual assist arms pay back the cost difference quickly in throughput and reduced damage claims.
WB11 Computerized Spin Balancer
The WB11 is a manual-data-entry balancer — diameter, width, and distance-to-flange are dialed in once per wheel and stored for the cycle. Balance speed is 150 rpm and the controller resolves correction weight position to 1.4 degrees with 1-gram total accuracy across the 10"–32" rim range.
Self-calibration at startup keeps the machine consistent between sessions. The 40mm shaft mounts the standard Atlas centering cone set included in the package, covering cars and light trucks with no extra adapter purchase needed.
The Right Dual-Arm Tire Service Combo for Your Shop
This pairing is the right answer for a tire bay that sees a steady mix of low-profile, run-flat, and custom-rim work. The dual assist arms on the TC289DAA take the operator strain out of stiff-sidewall tires, and the WB11 finishes the wheel with 1-gram balance accuracy.
Both machines run on 110V single-phase power and arrive with the full operator accessory pack — inflation box, FRL unit, lube bucket and brush, jaw protectors, centering cones, pliers, calipers — so the bay is functional uncrating day.
