Tire Changer Bars and Mount/Demount Tools: Types, Uses and What to Buy

The bar of a manual tire changer is three tools in one: the handle of the bead breaker, the wrench for the post cap and the lever that takes the tire off and puts it on. It comes with the changer. What is sold separately are different tools: duck-head kits that take over the bar's work at the rim, tire irons for small wheels, and long mount/demount bars for 22.5 to 24.5 inch truck tires. Which one you need depends on the wheel, not on the word bar.

Bottom line

A floor-post manual tire changer includes its mount/demount bar, and its manual says to use only included accessories. If the bar marks your rims, a duck-head kit replaces its job at the rim edge. For motorcycle and small tires, tire irons do the work without a stand. The long steel mount/demount tools sold for 22.5 to 24.5 inch wheels are for semi truck tires only and are no spare bar for a car tire changer.

The bar of a manual tire changer: what it does

We describe the bar from the copy of the owner's manual on ManualsLib for the reference machine, Harbor Freight item 58731, and paraphrase it. The specifications list a bead breaker handle that includes the mount/demount bar. In the working steps the one bar has three jobs.

  1. Handle of the bead breaker. The bar is pushed into the bead breaker handle and gives the leverage to press the shoe down on the tire next to the rim edge.
  2. Wrench for the post cap. The flat end of the bar tightens and loosens the cap that holds the wheel on the center post.
  3. Lever at the rim. To demount, the mount/demount end is set against the bead, pushed down and drawn around the rim with the post cap as the fulcrum. To mount, the flat end works the lower bead over the rim edge; then the bar is turned around and its hook end wedges the upper bead under the rim, section by section. For more leverage the manual has you slide the bar along the center post.

Two consequences follow. The bar only works together with the post: it is a lever that needs the post as its pivot, which is why the stand has to be fixed down. And it is bare steel that travels along the rim flange. The manual itself cautions against use on tires with high-end rims and warns that scratches and slight marring can result.

We found no length for the bar in the documents we read, so we name none.

Can you replace or upgrade the bar?

A spare of the original. The manual copy notes that some parts in its parts list are shown for illustration only and are not available individually as replacement parts. Whether the bar is one of them is a question for Harbor Freight; have the item number ready. For changers of other brands, ask the seller.

A different steel bar. Where a third-party bar is offered with the name of the Harbor Freight machine in its title, that is seller wording. The manual says to use the changer only with the accessories that are included and not to modify it, and no document we read states that a third-party bar matches the post cap, the handle socket and the rim geometry of a given machine. We list no such bar.

A head in place of the tip. This is the upgrade with at least a principle behind it. The tire makers recommend machines with composite mount/demount heads to avoid damage to the rim and the tire bead, and they strongly recommend plastic-coated tire levers with rounded ends. A duck-head kit puts a shaped head on an arm that pivots on the post, so the bar no longer slides along the rim.

The EXODIOS duck-head kit* (paid link) is a kit that its seller lists for manual tire changers; fit is a seller statement, so measure the center post first. It is a third-party part too, and outside what the Pittsburgh manual covers. The kits are compared under duck-head kits, and the question of marks has its own page: will a manual tire changer scratch alloy rims.

Help for the hand that is not on the bar. While the bar levers one section of the upper bead on, the opposite section has to stay in the drop center. Nylon bead clamps* (paid link) are listed for that. All add-ons are sorted on the page about manual tire changer upgrades.

Bars for truck tires: a different tool for a different wheel

The long steel bars sold as tire mount/demount tools are made for the tubeless tires of trucks, buses and trailers on 22.5 and 24.5 in. wheels. They are hand tools that are used without a tire machine.

We link to no bar of this kind. OSHA's procedure chart for tubeless truck and bus tires says the work must only be performed by trained personnel, so these bars are described here only to keep them apart from the bar of a car tire changer: they are no spare bar for it and no tool for pickup wheels.

VEVOR's own site shows a kit of this kind under model number XJC-008. According to that page it has three pieces, a demounting tool, a mounting bar and a bead keeper made of reinforced nylon, is stated for 22.5 to 24.5 in. tires on buses, heavy trucks and trailers, and has a nylon roller on the demounting tool that is meant to spare the wheel. VEVOR sells more than one variant.

Tire irons: the bar without a machine

For motorcycle, lawn tractor and other small tires the lever is a pair or trio of hand irons, used with rim protectors and without a post. Length is the main choice: the Dr.Roc irons* (paid link) are listed at 19.5 in. according to the seller, the NEIKO spoon set* (paid link) measures 14.5 in. according to the manufacturer and includes three rim protectors. A longer iron gives more leverage and puts more force on the rim edge. Sets and lengths are compared under tire spoons. Irons are not a substitute for the bar of a car tire changer: we found no maker's instructions for changing car tires with irons alone.

What makes any bar work

A longer or stronger bar is rarely the missing piece. Three things decide how hard you have to pull.

  • The drop center. The bead is smaller than the rim flange. It passes only when the opposite side of the bead sits in the deep channel in the middle of the rim. The tire makers call for the beads to be completely in the drop well during mounting.
  • Lubricant. Both beads and the rim are lubricated with a product made for mounting. A dry bead drags on steel and nylon alike.
  • Small bites. The manual's steps move the bar around the rim a section at a time.

The full sequence is under how to use a manual tire changer.

Typical mistakes

  • Ordering a truck bar for a car changer. The range in the listing is the wheel size the tool is shaped for.
  • Slipping a pipe over the bar. More leverage means more force on post, base and rim than the machine was described for; the manual says not to modify it.
  • Hitting the tire with the bar. The manual warns against striking the side of the tire with the bar during mounting.
  • Blaming the bar for a dry bead. If the bead is not lubricated and not in the well, no bar helps.
  • Working without eye protection. The manual calls for ANSI-approved safety goggles and heavy-duty work gloves. A bar under load can slip.

What to check before you buy

  1. Name the wheel: rim diameter and vehicle class. That decides which of the four tools you are looking for.
  2. For a duck-head kit, measure the outside diameter of the center post.
  3. For a truck tool, read which pieces the listing includes and compare the stated range with your wheels.
  4. For irons, check length and whether rim protectors are in the set.

The bottom line

If you own a manual tire changer, you already own its bar; the useful additions are a duck-head kit for the rim edge and bead clamps for the drop center, both third-party parts outside the machine's manual. For small tires, buy irons. Bars for 22.5 to 24.5 in. truck wheels are tools for trained tire service; what that job requires is on the page about truck tire changers. All tool types and their limits are on the manual tire changer homepage.

Straight answers

What is the bar on a manual tire changer called?

The owner's manual of the reference machine calls it the mount/demount bar. It has a flat end and a hook-shaped mount/demount end. Listings also call it a tire changer bar, tire tool or lever bar. On truck tire tools the words demount tool and mounting bar name two separate bars, one for taking the tire off and one for putting it on.

Can I buy a replacement bar for a Harbor Freight tire changer?

The copy of the owner's manual on ManualsLib lists the bar as part of the bead breaker handle and notes that some parts are shown for illustration only and are not available individually as replacement parts. We could not check whether Harbor Freight sells the bar on its own. Ask Harbor Freight with the item number 58731 before you buy a third-party bar, whose fit nobody documents.

Is there a no-scuff bar for a manual tire changer?

Marks are possible with any bar. The tire makers strongly recommend plastic-coated tire levers with rounded ends and composite mount/demount heads, because steel on the rim edge is what causes marks. For a manual changer the documented step in that direction is a duck-head kit with a nylon head, not a different steel bar.

Can I make my own tire changer bar?

People do, and we give no instructions for it. No tool maker or tire maker we read describes a homemade bar, and the manual of the reference changer says not to modify the machine and to use it only with the accessories included. The bar carries the full lever force next to your hands and face; a bar that bends or slips is a hazard, not a saving.

Will a 22.5 inch truck tire tool work on pickup or car wheels?

It is not made for them. VEVOR's own page for a kit of this kind states 22.5 to 24.5 inch tires on buses, heavy trucks and trailers, and we link to no such bar: that work is for trained tire service. Car, pickup and trailer wheels up to 16 inches belong on a manual tire changer; larger and low-profile wheels belong in a shop.
