Triumph NTC-950 Swing-Arm Rim Clamp Tire Changer
What the NTC-950 is built for
The NTC-950 is the entry point into the Triumph rim-clamp line: a stand-alone four-jaw clamping turntable with no helper arm, aimed at shops getting into tire service without overbuying a machine. It mounts and demounts passenger-car and light-truck tires and is rated for vehicles up to 1 ton, including Load Range C, D, and E tires. As tire volume grows, the design accepts one or two helper arms, so the machine can be expanded rather than replaced. If you would rather buy the expanded configuration up front, the same machine is stocked pre-fitted with a single assist arm as the NTC-950-1 or with two arms as the NTC-950-2. For a one- or two-bay commercial shop doing car and light-truck work, the stand-alone version is designed for single-operator use as delivered.
Clamping range, tire sizes, and what it will not do
The turntable clamps rims from 16 to 28 inches on the inside and 14 to 26 inches on the outside. Maximum wheel width is 15 inches and maximum tire diameter is 43 inches. In terms of fitment, the machine is rated for 14- to 24-inch and 16.5-inch wheels on passenger cars and light trucks up to 1 ton. Motorcycle wheels can be serviced with an additional adapter. Know the limits before you buy: the NTC-950 is not rated for box trucks, over-the-road trucks, 19.5- or 21.5-inch wheels, implement tires, or run-flat tires. Those jobs call for a larger machine in the Triumph tire-changer line. Run-flats specifically are handled by the two-arm NTC-950-2, not by the stand-alone machine or the single-arm NTC-950-1.
Power, air, and shop requirements
The clamping turntable is driven by a 1.5 HP motor on 110 volts, so most one- and two-bay shops can plug the machine in without adding a new circuit or bringing in an electrician for 220V service. The bead breaker is air-powered and delivers 5,500 lbs of force, and the built-in bead blast system uses a burst of air to help seat stubborn beads. Maximum air pressure is 120 PSI. An inline air filter and regulator with an oiler and water separator conditions incoming shop air before it reaches the cylinders and valves. Assembled, the machine measures 56" x 40" x 80", so plan the bay space and overhead clearance around that footprint and height before the crate arrives.
Build details and serviceability
The bead-breaker cylinder, rim-clamp cylinder, and foot-pedal valve are aluminum, and the external air lines use all-metal fittings rather than plastic push-connects. Plastic clamp covers sit over the steel jaws to shield rims during clamping. A removable front access plate lifts off for direct access to the foot-pedal valve assembly, which is the part most likely to need attention over the life of the machine — that access alone saves teardown time on a routine valve service. The NTC-950 carries Triumph's standard 1-year parts warranty. It ships by freight in a crate measuring 51" x 38" x 51" with a shipping weight of 700 lbs, and shipping is free to the lower 48 United States.
