Abstract

A tire removal tool for removing a tire from a dual wheel assembly has a handle having a gripping portion configured to be manually gripped, a head configured for introduction into the space between the wheels, and an intermediate portion connected between the handle and the head. The intermediate portion has a bent configuration so that the tool can extend over the outermost wheel with the head in contact with the inside of the wheel and the handle manually accessible at the outside of the wheel. The head includes an engagement surface arranged to simultaneously contact the sidewall of the innermost wheel to act as a fulcrum for transmitting an upward force applied to the handle to a force at the distal end of the head sufficient to dislodge the tire bead from the rim.

First claim

What is claimed is:

1. A tire removal tool for removing a tire from a dual wheel assembly having a first wheel and a second wheel adjacent the first wheel and defining a space therebetween, each wheel including a tire mounted on a wheel rim, each tire including beads in contact with the rim and sidewalls extending from the beads, the tool comprising:
a handle having a gripping portion configured to be manually gripped;
a head configured for introduction into the space between the wheels, said head having a distal end configured to contact the a bead of the tire of the first wheel and an engagement surface arranged to simultaneously contact a sidewall of the second wheel; and
an intermediate portion connected between said handle and said head and configured to extend over the first wheel with said handle manually accessible at the outside of the first wheel.

2. The tire removal tool of claim 1 , further comprising an elongated bar forming said handle and said intermediate portion.

3. The tire removal tool of claim 2 , wherein said head is affixed to said elongated bar.

4. The tire removal tool of claim 3 , wherein:
said head includes a distal end for initially contacting the first tire; and
said elongated bar includes a beveled end offset from said distal end of said head, said beveled end configured to engage the bead of the first tire when said distal end is advanced into the first tire.

5. The tire removal tool of claim 1 , wherein said intermediate portion includes at least two bends from said handle to said head, said at least two bends configured to pass over the first tire.

6. The tire removal tool of claim 5 , wherein a first one of said at least two bends closest to said handle is about forty (40) degrees.

7. The tire removal tool of claim 6 , wherein a second one of said at least two bends closest to said head is about ninety (90) degrees.

8. The tire removal tool of claim 7 , wherein said handle is connected to said intermediate portion at an angle of about 80 degrees relative to an axis of said handle.

9. The tire removal tool of claim 8 , wherein said intermediate portion includes straight sections between said at least two bends.

10. The tire removal tool of claim 9 , wherein said intermediate portion includes a first straight section between said handle and a first bend, a second straight section between said first bend and a second bend, and a third straight section between said second bend and said head.

11. The tire removal tool of claim 9 , wherein:
said first straight section has a length of about ten inches;
said first bend is at about forty (40) degrees;
said second straight section has a length of about six (6) inches;
said second bend as at about ninety (90) degrees; and
said third straight section has a length of about three (3) inches.

12. The tire removal tool of claim 1 , wherein said handle is connected to said intermediate portion at a non-perpendicular and non-co-linear angle.

13. The tire removal tool of claim 12 , wherein said handle is connected to said intermediate portion at an angle of about 80 degrees relative to an axis of said handle.

14. The tire removal tool of claim 1 , wherein said engagement surface of said head is an elongated surface having a length of between about eight (8) and about twelve (12) inches.

15. The tire removal tool of claim 14 , wherein said engagement surface of said head is curved toward the handle at a radius.

16. The tire removal tool of claim 1 , wherein said head includes a distal end having a width adapted for applying force to the first tire, said width being about three (3) inches.

17. A tool for separating a tire bead from a wheel rim for a dual wheel assembly, the tool comprising:
a head having a proximal end and a distal end, said distal end configured to engage the tire bead of the tire of an outboard wheel of the dual wheel assembly, said head further including a flat surface opposite adjacent said proximal end and configured to contact an outboard sidewall of the tire of an inboard wheel of the dual wheel assembly when said distal end is engaged with the tire bead of the tire of the outboard wheel; and
an elongated handle coupled at one end to said head, and including a gripping portion at an opposite end thereof configured for manual grasping by a user and an intermediate portion extending between said gripping portion and said one end, the intermediate portion having a number of curved sections providing for the handle to bend away from and back toward the gripping portion and configured to be positioned over the outboard wheel when said head is in contact with the outboard sidewall of the tire of the inboard wheel with said gripping portion accessible outside the outboard wheel.

18. The tool for separating a tire bead from a wheel rim of claim 17 , wherein said handle includes an elongated bar having a beveled end offset from said distal end of said head, said beveled end configured to engage the bead of the first tire when said distal end is advanced into the outboard tire.

19. The tool for separating a tire bead from a wheel rim of claim 17 , wherein said intermediate portion includes at least two bends from said gripping portion to said head.

20. The tool for separating a tire bead from a wheel rim of claim 19 , wherein said intermediate portion includes straight sections between said at least two bends and said gripping portion.
