BeadBuster XB-450i, XB-450 and XB-455: How the Clamp-and-Ram Bead Breaker Works

Who is behind the brand

BeadBuster describes itself as founded by two powersports enthusiasts and do-it-yourself mechanics who wanted something between hand tools and a paid tire service. The company sells through its own website, and its small model is also in our selection. It names ATV and motorcycle riders, off-roaders, racers, farmers and mobile tire mechanics as its customers and marks its tools as made in the USA. The design is patented.

Everything on this page comes from the maker's product pages and instructions. We have run no trials with the tool.

How the clamp-and-ram principle works

• Two feet on the ram slip into the gap between the rim lip and the tire bead.
• The clamp bolt pulls a clamp arm against the outside of the rim lip, so the tool sits on the rim and cannot walk away.
• The ram bolt then drives the feet down and pushes the bead past the bead retainer, the ridge this site calls the safety hump.

For the XB-450i the maker states up to 4.2 tons of clamp force and 9 tons of ram force, a ram travel of 1.438 in., and no adjustment for different wheel sizes. Both bolts take a 3/4 in. wrench. Because the force stays between tool and rim, the wheel needs no stand and nothing is bolted to the floor. More types of hand-operated tools are sorted under manual bead breakers.

Our pick: ATV & stiff sidewallsAd

BeadBuster

BeadBuster XB-450i

Clamps onto the rim lip and drives a ram between rim and bead with a wrench. No stand, no floor space.

Why here: The current small BeadBuster: 3 lb, driven with a 3/4 in. wrench, stated by its maker for one-piece wheels with tires up to 32 in. tall and designed around ATV and UTV rims of 9 in. and larger.

Best for: ATV and UTV tires with stiff sidewalls, and anyone who wants a bead breaker that fits in a toolbox.

What it does well

• For any one-piece wheel with a tire up to 32 in. tall, according to the manufacturer
• No adjustment for different wheel sizes; driven with a 3/4 in. wrench
• Hardened chrome-moly steel body, made in the USA (manufacturer)

Where it falls short

• Premium price class, the highest among the bead breakers here
• 7 and 8 in. ATV rims need a spacer that is sold separately
• Tire irons are still needed to take the tire off the rim

The body and ram foot are investment castings of hardened chrome-moly steel. The maker names ATVs and UTVs, motorcycles and scooters, cars, trucks, trailers, lawn mowers and garden tractors, go-karts and light aircraft as uses.

The limits the maker states

• One-piece wheels only for this model, with a tire of 32 in. or smaller.
• Rim lip. At most 1.70 in. wide and 0.63 in. thick, and at least 0.585 in. deep.
• 7 and 8 in. ATV rims. The tool is designed for ATV and UTV rims of 9 in. and larger. On the smaller rims the feet can catch on the bead retainer; the maker requires a spacer that is sold separately and says damage from use without it is not covered by the warranty. Lawn mower and go-kart wheels need no spacer, according to the page.
• Reinforced ATV rims with a rock ring need a clamp arm post, and contoured automotive rims an extended clamp arm. Both are sold separately.
• Not a tire changer. The maker says tire irons are required to finish the job. Sets are compared under tire spoons.

The lineup: XB-450i, XB-550i HD, XB-650i

All figures are the maker's. When we looked in October 2026 the XB-650i was offered for pre-order. Multi-piece wheels are outside the scope of this site.

XB-450 and XB-455. These names belong to earlier versions of the small tool. The maker's shop still lists spare parts for discontinued bead breakers. A maker's page for the XB-455 could not be opened, so we do not describe how it differed.

Using it: what the instructions stress

The maker's instructions stress three points. The steps for all tool types are under how to break a tire bead.

1. Empty tire. Remove the valve core and release all pressure before the tool touches the wheel.
2. Start on the shallow side, the side nearest the drop center, usually the outside face of the wheel, and lubricate the bead.
3. Keep the tool square to the rim. The body should sit within 1/8 in. of the rim edge and roughly perpendicular to the rim face. Leaning toward the rim from over-clamping, the ram foot can gouge the bead retainer; leaning away, it can slide down the sidewall and puncture it. The maker calls over-clamping the most common user problem.

Then loosen both bolts, move the tool along the rim and repeat.

On lubricant the maker names its own mounting lube or another lubricant such as soapy water. The tire makers' bulletin is narrower: it names commercially available lubricants made for bead seating first and does not name household soap. The details are under tire mounting lube.

Strengths and weaknesses

For whom, and the alternatives

The BeadBuster suits ATV and UTV owners with stiff sidewalls and anyone who wants a bead breaker that travels in a toolbox. The types are compared by tire in the overview of tire bead breakers. For two-wheelers, see motorcycle bead breakers, and for farm tires tractor tire bead breakers.

Once the new tire is on, the limit for inflation is the same with any tool: never more than 40 psi to seat beads; if they are not seated at 40 psi, deflate completely, reposition the tire on the rim, relubricate and reinflate. Read how to seat a tire bead before you inflate. All tools are sorted on the manual tire changer homepage.
