Tire Change Jacks
What Are Trailer Tire Change Jacks?
A flat tire on the side of the road is stressful enough when it happens to your car. When it happens to a loaded boat trailer or RV trailer, the challenge is a whole different problem. Standard scissor jacks and bottle jacks require careful placement, slow manual cranking, and a great deal of patience — none of which you want to spend on a busy highway shoulder. That's exactly why purpose-built trailer tire change jacks exist.
Unlike conventional automotive jacks, trailer tire change jacks are engineered specifically for the geometry and weight distribution of trailering applications. The most innovative designs work by using the tow vehicle itself to do the lifting. You simply position the jack under or near the axle, then drive forward or reverse a few inches — and the jack's cam-action mechanism raises the wheel clear of the ground. No pumping, no cranking, no getting under a heavy trailer.
How Do Drive-On Trailer Jacks Work?
The drive-on or "quick-change" style jack is the leading solution for marine and light RV trailers. The jack is placed on the ground under the trailer axle, close to the inside of the wheel that needs to be raised. As the tow vehicle moves forward slightly, the jack's curved profile acts as a ramp, using cam action to lift the axle and suspend the tire off the ground. Once the tire is raised, the driver puts the vehicle in park, sets the parking brake, and the tire change can begin safely.
These jacks are typically compact and lightweight — easy to stow in a truck bed, tackle box, or strapped to the trailer frame — so they're always there when you need them. Many models feature predrilled holes that allow permanent mounting to the trailer itself, ensuring you're never caught without it.
Key Considerations When Shopping for a Trailer Tire Change Jack
- Weight capacity: Make sure the jack is rated to handle at least the axle load of your trailer when loaded.
- Wheel size compatibility: Most drive-on jacks are designed for a specific range of wheel diameters, commonly 10" to 15" for boat and light utility trailers.
- Axle type: Confirm the jack is compatible with your axle profile — round and square axles are both common on boat trailers.
- Surface conditions: Some jacks grip better on packed surfaces; carrying a small piece of scrap lumber can help stabilize the jack on hard or slick pavement.
- Portability: High-strength aluminum construction keeps weight down and resists the corrosion that's inevitable in marine environments.
