Mounting a Manual Tire Changer: Concrete Floor, Pallet Base or Hitch Mount

What this guide rests on

Result: a stand that does not move when you put your weight on the bar. Effort: one assembly session and, on concrete, a hammer drill.

The steps follow the owner's manual of the Harbor Freight Pittsburgh manual tire changer, item 58731, the reference machine of the floor-post layout. Harbor Freight's own PDF could not be opened from our location, so we read the copy on ManualsLib and paraphrase it; “the manual” on this page means that copy. Other brands use the same layout with their own hole patterns. VEVOR, for example, describes three predrilled holes in the base of its changer. Your machine's own manual comes first.

We have not mounted a changer ourselves. This is the documented procedure with its gaps named.

What the manual requires

The last row is the gap. The manual tells you where the holes are and how large, but not what goes through them.

Six steps

1. Choose the spot

   The surface has to be secure, level and able to carry the changer and the tire. The manual asks for a floor surface at least 4 in. deep. Leave free room all around: the bar is worked in a full circle around the post, and the bead-breaker arm needs space on the long end of the base.

2. Check for hidden utility lines

   Before you drill or drive screws, verify that no utility lines run in the mounting surface. In a garage slab that can mean heating pipes, conduit or a drain line. If you cannot rule them out, ask whoever built or maintains the building.

3. Assemble the base

   The manual has the center post, the side base and the mounting tab joined with hex bolts, washers and nuts. It calls for ANSI-approved safety goggles and heavy-duty work gloves during assembly. Follow the drawing for your own machine; part names and counts differ between brands.

4. Mark and drill

   Set the assembled base where it will stand and mark the mounting holes at the ends of the base parts. Choose anchors that pass the holes of your base, 7/16 in. on the reference machine, and that their maker approves for your floor. Drill to the diameter and depth the anchor maker specifies.

5. Fasten the base

   Mount the base through its holes and tighten the fasteners as their maker specifies. The stand must sit flat. If it rocks, the surface is not level enough.

6. Fit the bead breaker and check the stand

   Install the bead breaker handle in its bracket and the shoe on the handle with the clevis pins and R-clips; the manual offers two positions each, depending on tire size. Check that nothing is loose. The manual says to inspect the changer before every use and not to use it with loose or damaged parts.

The three mounting ideas people search for

Concrete floor with anchors

This is the first of the two surfaces the manual names. What it leaves open is the anchor. Anchor makers publish, for each product, the drill diameter, the embedment depth, the minimum distance to slab edges and joints, and the tightening torque. Those figures belong to the anchor, not to the tire changer, so take them from the packaging or data sheet of the anchor you buy. If you want the floor clear between tire changes, use an anchor type its maker describes as removable.

Wood pallet

The second surface the manual names. It gives no size, no weight and no way of loading the pallet, and we add none. The requirement from the safety section still applies in full: secure, level, able to support changer and tire. A pallet that tips or slides under the bar does not meet it.

Hitch mount, plywood sheet and other ideas

Videos and forums show stands bolted to a plywood sheet the user stands on and stands welded to a bar for a trailer-hitch receiver. None of the manufacturer sources we read for car changers describes either. The manual adds a point that bears on welding and adapting: the changer is not to be modified for tasks it was not designed for. These are user solutions, and we give no building instructions for them.

Typical mistakes

• Drilling before checking the slab. The manual puts the check for hidden lines in its safety section for a reason.
• Guessing the anchor. The hole in the base limits the diameter; the floor decides the type. Read the anchor maker's data.
• Too little room. The stand is small. The circle you walk with the bar is not.
• Mounting first, measuring wheels later. The reference machine is specified up to 16 in. standard tires. Check your rim sizes before you drill a floor for a tool that does not cover your wheels.
• Treating the mounted post as an inflation restraint. The manual says nothing of the kind. For inflation the tire makers' rules apply; see how to seat a tire bead.

Next steps

With the stand fixed, the work itself is described in how to use a manual tire changer. The store-bought original has its own page, the Harbor Freight tire changer. A second stand of the same layout is the TUFFIOM changer^* (paid link), listed for 8 to 16 in. tires according to the seller; how its base is fixed is not documented, so check the hole pattern when it arrives. All stands are on the manual tire changer overview and in the comparison of the best manual tire changers.
