Changing a Tractor Tire - Dismounting


We have put together a series on how to change a tractor tire yourself, eliminating the need to have a service truck come out. You will find step-by-step illustrations and instructions on dismounting and mounting the tire, removing and installing liquid ballast, and safety tips to follow when changing tires.

1. Stabilizing Tractor

Park tractor on solid level surface (concrete floor is best). Block front and rear wheels, raise tractor with jack and support with jack stand. Make sure tractor will not roll forward, backward or side to side when tire is being changed.

 


Larger tires may require larger irons and may require two people.

 

2. Bead Breaking (outside bead.)

For rim with valve stem on outside, position the rim with valve stem on top. Remove valve core to deflate tire. After tire is deflated, drive an iron between bead and lip of rim. This will loosen the bead from rim lip and make it easier to install Bead Bustertool. After loosening an area about 6" wide, insert the Bead Buster and drive between bead and rim flange. Lock Bead Buster to rim. Using a 1 1/4" socket and a 1/2" drive ratchet, turn screw head and force bead off rim seat. Repeat procedure to loosen inside bead (shown in picture at left).

3. Tube Inspection

If tube is stuck or rusted fast to rim, use one tire spoon to raise tire bead and a second spoon to pry tube up and loose from rim. This may need to be repeated around the entire rim.

4. Bead Lubrication

After both beads are removed from bead seat area, lubricate tire bead and bead seat area with a suitable lubricant.

 


NOTE: Larger tires may require large irons and may require two people.

5. Removing Tire from Rim (outside bead)

Lock the wheel with valve hole on top. Push the bottom of the tire inward. Insert long tire irons under the bead at the top of the rim and pry bead over lip of rim. Keep tire irons close together; this will make prying easier and help prevent bead damage.

After part of bead is over rim flange, hold iron in place and remove other iron to pry next portion of bead over rim. Do not pry too large a portion at once, it will be hard to pry and may tear the bead.

Maintain constant grip and pressure on the tire irons at all times. The irons may spring back with pressure if your grip is released. Work your way around the rim until the outside bead of the tire is completely over the rim.

 

 

6. Removing Tube

Tube can be removed from tire after the outside bead is completely over the rim. Start at the bottom and pull tube outward. Work your way up either side of the tire until the tube is completely removed.

 

7. Removing Tire from Rim (inside bead)

Insert two tire irons under bead on side of tire. Apply pressure on both irons and pull back on one iron to move bead over lip of rim. Continue around rim until inside bead of tire is completely over the rim. NOTE: To avoid bead damage, do not pry too large a portion at once as you move around rim.

8. Cleaning Rim

Once the tire is removed from the rim, wire brush rust from rim and clean surface of debris. Check rim for cracks on bead flanges. Also check area where rim is mounted to center plate. Make sure there are no sharp burrs on rim flange; these burrs could cut tube during installation or removal.

After rim has been cleaned, apply a thin coat of rust preventative to the bead seat area of rim.
