Hofmann monty® 3850 Heavy-Duty Truck Tire Changer
Buses, tractor-trailers, ag equipment, and OTR wheel assemblies need commercial-duty clamping and mounting power that a passenger-shop changer simply can't deliver, but not every commercial shop needs the widest rim range on the market. The Hofmann monty® 3850 is the entry point into Hofmann's commercial truck lineup: an electro-hydraulic drive system with a self-centering four-jaw chuck clamps 14"–26" rims, and a mobile remote control unit lets a single technician run the entire job instead of needing a second tech on every truck tire.
Against its closest sibling, the monty® 4400, the 3850 covers a narrower 14"–26" clamping range (versus the 4400's 14"–44" standard) at roughly $10,000 less. Both run on similar electro-hydraulic platforms with a mobile remote console, but the 3850 is sized for shops whose fleet mix tops out around 26" rims rather than the full range of commercial truck and OTR wheels the 4400 is built to reach.
Who the monty® 3850 Is Built For
- Shops entering commercial truck tire service for the first time that need Hofmann's entry-point electro-hydraulic changer without paying for the 4400's wider 44" range.
- Fleet shops running tube-type, tubeless, multi-piece, Budd, and Dayton wheel assemblies — the 3850 services all of them on one machine.
- Bays that want one-man operation on truck tire jobs — the mobile remote control unit avoids the second-tech labor cost manual truck tire service usually requires.
- Shops running 208V single-phase power (versus the 4400's 208V three-phase) looking for commercial-duty capability without a three-phase electrical upgrade.
- Operations handling wheel assemblies up to 2,205 lbs. and 59" diameter — within the 3850's stated capacity for standard commercial truck work.
- Shops that need the tilting bead breaker disk and patented mount/demount system to handle stiff commercial sidewalls without a second dedicated bead-seating tool.
What the monty® 3850 Is NOT Built For
If your fleet runs larger 44"+ rim assemblies, the 3850's 26" clamping range won't cover it. The Hofmann monty® 4400 reaches up to 44" standard for fleets running the larger end of commercial truck wheels.
What Makes the monty® 3850 Different
Electro-Hydraulic Drive System
Powerful, precise control sized for buses, tractor-trailers, agricultural equipment, and OTR applications — the entry point into Hofmann's commercial truck lineup.
Hydraulic Four-Jaw Chuck
Self-centering chuck securely clamps large wheel assemblies without technician-manual centering.
Mobile Remote Control Unit
Lets one technician safely operate the entire machine from a distance, avoiding the second-tech labor cost of manual truck tire service.
Integrated Bead Breaker + Patented Mount/Demount
Combines bead breaking and mounting tools into one system, with a tilting disk that maintains optimal positioning for efficient bead work on commercial sidewalls.
Versatile Wheel Compatibility
Services tube-type, tubeless, multi-piece, Budd, and Dayton wheel assemblies — one machine covers the mixed fleet most commercial shops actually see.
- Fleets with 14"–26" rim commercial truck wheels
- Shops entering commercial truck service on a budget
- Fleets running 44"+ rim assemblies
- Shops needing 208V three-phase power capability
