Pressure by the tyre against the passenger cabin causes its deformation and the tyre gets destructed and deflated, thus allowing for additional deformation of the deformation zone up to the moment of the contact between the rim and the passenger cabin. A destruction member for the tyre is situated in the area of the contact occurring in the deformation zone between the tyre and the passenger cabin. The destruction member may be formed by spikes, punches or cutting edges and is fitted with puncturable covers. ## Claims ### Claim 1 A device for effective use of a deformation zone of a motor vehicle body having a passenger compartment, the device comprising: at least one deformation zone attached to the passenger compartment; at least one vehicle wheel having a rim surrounded by an inflated pneumatic tire, the wheel being located in the deformation zone near the passenger compartment; at least one destruction member fixed between the passenger compartment and the inflated pneumatic tire of the wheel for puncturing and deflating the tire upon deformation of the deformation zone. ### Claim 2 A device for effective use of a deformation zone of a motor vehicle body having a passenger compartment with a front part and a rear part, the device comprising: a front deformation zone attached to the front part of the passenger compartment; a rear deformation zone attached to the rear part of the passenger compartment; a front vehicle wheel located in the front deformation zone near the front part of the passenger compartment; a rear vehicle wheel located in the rear deformation zone near the rear part of the passenger compartment; each of said wheels having a rim surrounded by an inflated pneumatic tire; at least one destruction member fixed between the front part of the passenger compartment and the inflated tire of the front wheel and at least one destruction member fixed between the rear part of the passenger compartment and the inflated tire of the rear wheel for puncturing and deflating the tires upon deformation of the deformation zones. ### Claim 3 (depends on 1) The device according to claim 1, wherein the destruction member has a puncturable cover. ### Claim 4 (depends on 1) The device according to claim 1, wherein the destruction member comprises a plurality of spikes having tips extending toward the tire and bases mounted to the passenger compartment. ### Claim 5 (depends on 1) The device according to claim 1, wherein the destruction member comprises a plurality of cutting edges. ### Claim 6 (depends on 1) The device according to claim 1, wherein the destruction member comprises a plurality of punches. ### Claim 7 (depends on 1) The device according to claim 1, wherein the puncturable cover of the destruction member is a wheel arch guard. ### Claim 8 (depends on 2) The device according to claim 2, wherein the destruction member has a puncturable cover. ### Claim 9 (depends on 2) The device according to claim 2, wherein the destruction member comprises a number of spikes having tips extending toward the tire and bases mounted to the passenger compartment. ### Claim 10 (depends on 2) The device according to claim 2, wherein the destruction member comprises a plurality of cutting edges. ### Claim 11 (depends on 2) The device according to claim 2, wherein the destruction member comprises a plurality of punches. ### Claim 12 (depends on 2) The device according to claim 2, wherein the puncturable cover of the destruction member is a wheel arch guard.
