Abstract
Abstract A pneumatic vehicle tire, especially spare tire, which, when in deflated position on a wheel, has its sidewalls folded over the wheel flange so that the folded-over tire sidewall portion together with the adjacent bead portion will be U-shaped in cross section with the opening of the U directed toward the axis of rotation of said vehicle.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
163 words
A pneumatic tire adapted to be installed on a wheel rim and to be inflated to tire shape of horseshoe cross section, comprising beads with bead cores, and, in deflated condition, foldable, extensible elastic sidewalls and an approximately cylindrical, extensible elastic tread strip, each of said sidewalls, when said tire is mounted on a rim, being folded over outside of the flange of the rim to form a folded portion Ushaped in cross section extending circumferentially about each side of the rim, and said tread strip having an internal diameter approximately the diameter of said rim flanges increased by the thickness of said sidewalls on diametrically opposite sides of the rim, so that said tread strip rests on the sidewalls folded over said flanges, and said tread strip and sidewalls being extended by inflation of the tire to assume the horseshoe shape in cross section, with the tread strip of substantially increased diameter and the sidewalls extending substantially radially outward from said beads.
Claim 2
Dependent Claim
163 words
A pneumatic tire adapted to be installed on a wheel rim and to be inflated to tire shape of horseshoe cross section, comprising beads with bead cores, and, in deflated condition, foldable, extensible elastic sidewalls and an approximately cylindrical, extensible elastic tread strip, each of said sidewalls, when said tire is mounted on a rim, being folded over outside of the flange of the rim to form a folded portion Ushaped in cross section extending circumferentially about each side of the rim, and said tread strip having an internal diameter approximately the diameter of said rim flanges increased by the thickness of said sidewalls on diametrically opposite sides of the rim, so that said tread strip rests on the sidewalls folded over said flanges, and said tread strip and sidewalls being extended by inflation of the tire to assume the horseshoe shape in cross section, with the tread strip of substantially increased diameter and the sidewalls extending substantially radially outward from said beads.
Claim 3
Dependent Claim
61 words
A vehicle tire according to claim 1 which includes cushioning means interposed between said wheel flanges and the respective sidewall portion folded thereover, said cushioning means being connected to said last-mentioned elastically folded-over sidewall portion so that thinner more sensitive and elastic sections of the tire sidewalls during emergency spare tire running are kept from being subjected to any material stresses.
Claim 4
Dependent Claim
158 words
A pneumatic tire adapted to be installed on a wheel rim and to be inflated to tire shape of horseshoe cross section, comprising beads with bead cores, and, in deflated condition, foldable, extensible sidewalls and an approximately cylindrical, extensible tread strip, each of said sidewalls, when said tire is mounted on a rim, being folded over the side flanges of the rim to form a folded portion U-shaped in cross section extending circumferentially about each side of the rim with the bight of the U-shape toward the axis of the wheel rim, said tread strip having an internal diameter approximately the diameter of the rim flanges increased by the thickness of the sidewalls on opposite sides of the rim, and said tread strip and sidewalls being extended by inflation of the tire to assume the horseshoe shape in cross section, with the tread strip of substantially increased diameter and the sidewalls extending substantially radially outward from said beads.
Claim 5
Dependent Claim
158 words
A pneumatic tire adapted to be installed on a wheel rim and to be inflated to tire shape of horseshoe cross section, comprising beads with bead cores, and, in deflated condition, foldable, extensible sidewalls and an approximately cylindrical, extensible tread strip, each of said sidewalls, when said tire is mounted on a rim, being folded over the side flanges of the rim to form a folded portion U-shaped in cross section extending circumferentially about each side of the rim with the bight of the U-shape toward the axis of the wheel rim, said tread strip having an internal diameter approximately the diameter of the rim flanges increased by the thickness of the sidewalls on opposite sides of the rim, and said tread strip and sidewalls being extended by inflation of the tire to assume the horseshoe shape in cross section, with the tread strip of substantially increased diameter and the sidewalls extending substantially radially outward from said beads.
Claim 6
Dependent Claim
26 words
A pneumatic tire as claimed in claim 3, in which the bight of each U-shaped portion has a diameter less than the diameter of a bead.
