Abstract
Abstract A method of mounting a pneumatic tire on a wheel rim having side flanges and a radially inwardly depressed well portion comprises fitting the tire to the rim by a method employing the said well portion, and subjecting the well portion of the rim to axial compression so as to reduce the axial width of the well portion.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
74 words
A method of mounting a pneumatic tire on a wheel rim having side flanges and a circumferentially extending radially inwardly depressed well portion comprising fitting the tire to the rim by a method employing the said well portion to enable the tire beads to pass over a rim flange, and subsequently subjecting at least the well portion of the rim to axial compression so as to reduce the axial width of the well portion.
Claim 2
Independent Claim
74 words
A method of mounting a pneumatic tire on a wheel rim having side flanges and a circumferentially extending radially inwardly depressed well portion comprising fitting the tire to the rim by a method employing the said well portion to enable the tire beads to pass over a rim flange, and subsequently subjecting at least the well portion of the rim to axial compression so as to reduce the axial width of the well portion.
Claim 3
Independent Claim
134 words
A method of mounting a pneumatic tire on a sheet metal wheel rim having side flanges and a circumferentially extending radially inwardly depressed well portion comprising fitting the tire to the rim by a method employing the said well portion to enable the tire beads to pass over a rim flange, placing the tire and rim assembly in a press having a pair of dies which engage the outer sides of the well and moving the dies axially relative to one another to compress the rim axially and to deform the said well portion into a circumferentially extending bead portion formed between the dies in the closed position thereof, the rim having in its final state after the pressing operation a radially inwardly projecting circumferentially extending bead portion corresponding to the original well portion.
Claim 4
Independent Claim
134 words
A method of mounting a pneumatic tire on a sheet metal wheel rim having side flanges and a circumferentially extending radially inwardly depressed well portion comprising fitting the tire to the rim by a method employing the said well portion to enable the tire beads to pass over a rim flange, placing the tire and rim assembly in a press having a pair of dies which engage the outer sides of the well and moving the dies axially relative to one another to compress the rim axially and to deform the said well portion into a circumferentially extending bead portion formed between the dies in the closed position thereof, the rim having in its final state after the pressing operation a radially inwardly projecting circumferentially extending bead portion corresponding to the original well portion.
Claim 5
Dependent Claim
60 words
A method according to claim 1 wherein the rim and tire assembly is placed in a press having at least one die incorporating at least one pressing ring which is arranged to be compressed axially by the axial movement of said die and is thereby squeezed radially outwardly against the wheel rim to form a circumferentially extending radial protrusion therein.
Claim 6
Dependent Claim
71 words
A method according to claim 1 wherein a circumferentially extending deformable locking member is located in the well portion, and subsequently at least the well portion of the rim is subjected to axial compression so as to reduce the axial width of the well portion and to clamp the locking member therein, an outer peripheral region of the locking member being arranged to extend radially outwardly from the compressed well portion.
