You can check our HELP ME CHOOSE page to see if the XB-550 HD is compatible with your tractor tires, or other heavy equipment wheels. If you don’t know your vehicle’s rim code, you can measure your rim and compare it to the XB-550 spec’s.
The critical dimensions are the Rim Lip THICKNESS, DEPTH. and WIDTH. The lip thickness and width can be measured with the tire still on the rim, but to estimate the lip depth, you need to subtract inside diameter of your new tire from the outermost diameter of the rim.
Rim Lip Depth (d) = (Outermost Rim Dia. – Inside Tire Dia.) / 2
New Tire Inside Dia. = 46″
Outermost Rim Dia. = 48.26″
Lip Depth (d) = (48.26 – 46) / 2 = 2.26/2 = 1.13″
The XB-550 HD will work on:
Lip Depths (d): 0.585″ – 1.500″
Lip Thickness: < 1.75″
Lip Width: < 2.70″ (the overall rim lip width on the outside needs to be smaller than this figure)
1. Remove the valve core to release air pressure from tire.
2. Start with the ‘shallow’ side nearest the drop center…this is usually the outside of the wheel. Apply soapy water (or other lubricant, like WD-40) to the bead. Push down on the sidewall to ensure that soapy water flows in between the rim and tire.
3. Press the feet of BeadBuster XB-550 HD in between tire and rim. Use the Handle to aid in getting the feet positioned. The soapy water helps it slide in. Pressing the feet down onto the sidewall 1st helps create a small gap for the feet to enter. Make sure the feet are started in the tire-rim gap before clamping.
4. Use a 15/16” socket or wrench to tighten the clamp bolt to pull the feet all the way in and align the tool. You can use an impact wrench, ratchet, drill or hand wrench. A typical ATV tire requires 7-9 ft-lbs (112-144 in-lbs) of torque to get the feet in. Use caution with a 1/2″ pneumatic impact wrench to not over-torque the bolts, as you could damage the tool, tire and wheel.
5. Tighten the Clamp Bolt until the BeadBuster XB-550 HD is perpendicular to the face of the rim, and the tool body is touching the rim. Make sure the BeadBuster feet are fully inserted, on some wheels when fully inserted, there may still be a small gap between the tool body and rim.
>> IMPORTANT NOTE <<
If the bead breaker is not properly clamped, and not correctly aligned with the rim, the Ram Foot may be bent or damaged while breaking the bead!
If Over-Clamped and the tool is leaned in toward the rim, the Ram Foot could gouge the bead retainer causing damage to both the tool and rim. This is the most common problem users have with using the BeadBuster.
If Under-Clamped and leaned away from the rim, the Ram Foot could slide down the sidewall and possibly damage the tire.
