Duck Head Kits for Manual Tire Changers: Fit, Post Diameter and Limits

A plain manual tire changer mounts and demounts with the tip of a steel bar that slides along the rim edge. A duck head kit puts a shaped head between bar and rim. It is the upgrade owners of a floor-post changer look for most, and it is also the product with the boldest claims in its titles. This page sorts out what a kit does, how to check the fit, and where the limits stay the same.

What it does well

• Reinforced nylon head, meant to minimize rim damage (manufacturer)
• Centering cone included to keep the wheel from wobbling on the post
• From the maker of our first-choice changer, so the fit is stated by one source

Where it falls short

• Made for VEVOR manual tire changers; on other brands check the post diameter first
• The maker lists 16 to 21 in. wheels, while its own changer is specified for 8 to 16 in.
• Reduces contact with the rim; marks remain possible

VEVOR duck head kit with centering cone

Manufacturer data: reinforced nylon head, centering cone, 9.4 lb, for VEVOR manual tire changers. VEVOR lists the kit for 16 to 21 in. wheels, while it specifies its own changer for 8 to 16 in. The kit's range is a manufacturer claim about the kit; it does not rewrite the range of the stand. On a changer of another brand, check the post diameter before ordering.

EXODIOS duck head kit

The EXODIOS kit^* (paid link) is a listing for changers of other brands, known from seller data only and not a pick. According to the listing it adds a mount/demount head to a manual tire changer. It sits in the budget price class. We found no manufacturer page with specifications. Fit depends on the post of your machine, so compare the listing with your changer.

Krysolad bearing duck head adapter kit

The Krysolad kit^* (paid link) mounts the arm on a bearing, according to the listing, and sits in the mid-range price class, above the other kits. The seller lists 16 to 21 in. wheels. That is a seller statement; the changer underneath is still limited by its own manual. No manufacturer page found.

Atesilor duck head kit with centering cone

The Atesilor kit^* (paid link) is the one listing that states its fit in numbers: posts of 2 in. diameter, with a centering cone of 1.67 in., according to the seller. The head is cast steel according to the listing, so metal contact with the rim remains possible. The seller lists 16 to 21 in. wheels, with the same reservation as above.

How to check the fit: post diameter first

A kit's arm sits on or over the center post of the changer. That makes the outside diameter of the post the first number to check.

1. Measure the post of your changer with a caliper or a tape measure.
2. Compare it with the listing. The Atesilor listing names 2 in. posts. The VEVOR kit is made for VEVOR changers. The other two name manual tire changers in general.
3. Check what holds the wheel. A centering cone keeps the wheel from shifting on the post while the head runs around the rim. Two of the four kits name one in their data.

Harbor Freight does not publish a post diameter for its Pittsburgh changer on the product page. If you own that machine, measure it; do not rely on a title that says “for Harbor Freight”. And know what its manual says: use the changer only with the accessories included, and do not modify it. A third-party kit is therefore outside what Harbor Freight covers, and fitting one is your own decision.

What a duck head does not change

Marks on rims stay possible. The same manual cautions against use on high-end rims and warns of scratches and slight marring. The tire makers' bulletin recommends machines with composite heads and plastic-coated levers to avoid damage to rim and bead, which is the idea behind a nylon head. A recommendation is not a guarantee, and no maker of a manual tool gives one. A cast-steel head is still steel.

The drop center still does the work. A duck head guides the bead; it does not create slack. The bead opposite the head has to sit in the drop center of the rim, or the tire will not go over the flange with any tool.

Lubricant is not optional. A dry bead drags on the head and on the rim. Use commercially available bead lubricant on both beads; see tire mounting lube.

Typical mistakes

• Buying the kit for larger wheels. A kit is an upgrade for the wheels your changer is specified for.
• Ordering without measuring the post. Listings name “manual tire changers”; posts differ.
• Working without a fixed stand. A duck head needs a wheel that does not move. The changer has to be anchored; see the guide on how to use a manual tire changer.
• Expecting shop-machine results. If the rims are expensive, the page are manual tire changers worth it is the better first read.

The bottom line

For a VEVOR changer take the VEVOR duck head kit with cone^* (paid link); it is the one kit whose maker states material and fit. For other machines the EXODIOS kit is the common choice, after you have measured the post. Either way the kit makes the work on 8 to 16 in. wheels cleaner and leaves the limits of the stand where they are. A branded attachment sold through its maker's own shop is described under Lucid Autowerks Ultimate Manual Tire Changer. The overview of manual tire changers shows the whole range of tools, and how we research explains why seller statements are labeled as such.
