Katool KT-T850 110V Tire Changer with Tilt-Arm Design
Also known as: KT-T850, Katool Tire Changer KT-T850
This 110V tire changing machine handles 14 to 28 inch wheels with a 2.0 HP motor on standard single-phase power. At 750 pounds, the Katool KT-T850 commercial tire changer accommodates tires up to 47 inches in diameter and 15 inches wide for passenger vehicles and light trucks.
Key Features
Tilt-Back Arm Mechanism for Enhanced Access
The KT-T850's tilt-back arm mechanism allows the entire column to pivot backward, creating extra clearance for wheel mounting and demounting operations. This design reduces operator strain when handling larger wheels up to 47 inches in diameter.
- Backward tilt function works through integrated foot pedals
- Technicians can adjust working angle without releasing wheel grip
- Speeds up cycle times by eliminating manual wheel repositioning
- Heavy-duty pivots rated for 10,000+ cycles with minimal maintenance
Pull-Type Pedal Control System
The pull-type pedal control system provides precise control over turntable rotation, bead breaking, and column positioning. Operating at 6.8 revolutions per minute for controlled tire mounting without damaging alloy wheels.
- Pedal configuration keeps both hands free for positioning the tire
- Each pedal connects to pneumatic cylinders rated for 0.8-1.0 MPa (116-145 psi)
- Low-profile design prevents accidental activation during operation
- Consistent performance across thousands of tire changing cycles
Versatile Clamping Range
This rim clamp tire changer offers outside clamping from 14 to 26 inches and inside clamping from 16 to 28 inches, covering compact car to light truck wheel sizes. The wide range lets shops handle most tire work on a single tire mounting machine.
- Alloy steel jaws undergo carburization treatment to 0.8-1.1mm depth
- Whole quenching creates hard exterior while maintaining flexible core
- Metallurgical process extends jaw life by 40% over untreated steel
- Included jaw covers protect expensive alloy wheels from scratching
Professional-Grade Components
The 28-inch turntable features reinforced steel construction rated for wheels weighing up to 150 pounds. Universal shovel design works with both standard and low-profile tires.
- Improved assist arm provides additional leverage for stubborn beads
- Pure copper winding in 2.0 HP motor improves heat dissipation
- 200mm aluminum bead breaker cylinder handles run-flat tires
- Operating noise stays below 70 dB, meeting workplace regulations
Integrated Bead Blast System and Air Management
The built-in bead blast seater delivers concentrated air bursts to seat difficult beads without requiring separate inflation equipment. Works at 116-145 psi through the integrated pneumatic system.
- Seats beads in seconds rather than minutes
- High-quality lubricator provides consistent oil drops to pneumatic components
- Filters compressed air to remove moisture and debris
- Stainless steel mounting head with solution treatment resists wear

Model Comparison
Choose the KT-T850 when you need 110V power with 14-28 inch clamp range on a tilt-arm chassis. The comparison below highlights key differences between popular tire changer models.
| Katool KT-T850 (tilt-arm) | 47 in max tire dia; 15 in max wheel width; clamp 14-26 in (outside), 16-28 in (inside) | Turntable 6.8 rpm; 110V 1-phase; 2.0 HP; air 0.8-1.0 MPa (116-145 psi) | Assist arms; bead-blast seater; stainless mounting head with rim guards; carburized jaws; 200 mm bead-breaker | - |
|---|---|---|---|---|
| Coats 80C (center-clamp) | 50 in max tire dia; 15 in max rim width; 12-30 in external rim diameter (center-clamp) | 220V, 2 HP electric; air motor 0.5 HP; typical shop air 110-175 psi | Center-lock clamp; RoboRoller bead depressor; auxiliary bead sealer; swing-away mount/demount | Requires 220V power and center-clamp workflow; larger footprint than tilt-arm units |
| Ranger R980XR (swing-arm) | 50 in max tire dia; up to 15 in turntable tire width (mounting) | Electric/air drive; recommended air 140-165 psi; 2 HP class | Heavy bead breaker; compact swing-arm layout; large accessory trays | Swing-arm design lacks tilt-back clearance; narrower clamp ranges than 28 in inside |
| Triumph NTC-950 (tilt-arm) | 43 in max tire dia; 15 in max wheel width; 14-26 in outside, 16-28 in inside clamp | 110V; 1.5 HP; max 120 psi; bead breaker force 5,500 lb | Bead blast; common 110V power; similar clamp ranges to KT-T850 | Smaller max tire diameter (43 in); lower motor power (1.5 HP) |
The Katool KT-T850 excels when you need a 14 to 28 inch clamp range on 110V power with tilt back clearance, assist arms, and a bead blast system in a single tire changer. If you require center clamp workflow and have 220V, the Coats 80C fits but needs more space, while Ranger R980XR and Triumph NTC-950 trade off clamp range or overall capacity.

Frequently Asked Questions
What size wheels can the Katool KT-T850 handle?
The KT-T850 accommodates wheels from 14 to 28 inches using its dual clamping system. Outside clamping handles 14 to 26 inch wheels, while inside clamping covers 16 to 28 inch wheels. Maximum tire diameter reaches 47 inches with up to 15 inches of wheel width.
Does this tire changer require 220V power?
No, the KT-T850 operates on standard 110V single-phase power, unlike many commercial tire changers that need 220V. The 2.0 HP motor provides full power on a 20-amp circuit. You'll still need compressed air at 116-145 psi for pneumatic functions.
How does the tilt-back arm improve efficiency?
The tilt-back arm pivots the entire column backward, creating extra clearance for mounting large wheels up to 47 inches. This eliminates manual repositioning of heavy tires and reduces operator fatigue. The mechanism works through foot pedals, keeping both hands free for wheel handling during the mounting process.
What's included with the KT-T850 purchase?
The machine comes with jaw covers, spade covers, assist arms, mounting head, bead-blast seater, pull-type foot pedals, and lubricator/air filter system. The 200mm aluminum bead breaker cylinder and 28-inch turntable are integrated components. All pneumatic parts and the 2.0 HP motor are covered under warranty.
Can this machine handle run-flat and low-profile tires?
Yes, the 200mm aluminum bead breaker cylinder generates sufficient force for run-flat tire beads. The universal shovel design accommodates low-profile tires, while the assist arms provide extra leverage for stubborn beads. The bead-blast seater helps seat stiff sidewalls common on performance tires.
How much floor space do I need for installation?
Plan for an 8 ft x 8 ft minimum floor area to accommodate the 47-inch wheel swing radius. You'll need 10 feet of ceiling height for full tilt-back operation with large wheels. The machine weighs 750 pounds and requires four concrete anchor bolts for permanent installation.
Will this work for motorcycle wheels?
Yes, the KT-T850 works well for motorcycle wheels. The 14-inch minimum outside clamp size accommodates most motorcycle rim sizes, from sport bikes to cruisers. The protective jaw covers prevent damage to chrome and polished aluminum motorcycle wheels during mounting and demounting operations.
What maintenance does the KT-T850 require?
Regular maintenance includes checking the lubricator oil level weekly and cleaning the air filter monthly. The carburized steel jaws need inspection every 500 tire changes. Keep mounting head and plastic covers clean to prevent rim damage. Pneumatic cylinders require lubrication through the integrated oiler system.
