Arrangement for a vehicle, in particular for a motor vehicle , comprising: - a body shell side in which an opening is created, - a steered wheel which can occupy a volume (V) as the steered wheel changes direction, - a first door and a second door that are designed to close the opening , the first door and the second door being mounted so as to be able to move relative to the body shell side such that they are guided so as to each move substantially parallel to themselves during its opening and/or closing movements, the first door being arranged so as to open towards a first region of the of the body shell side that is intended to receive the steered wheel and the second door being arranged so as to open towards a second region of the body shell side that is intended to receive a non-steered wheel , the volume (V) extending in the transverse direction towards the outside of the cabin of such a vehicle over a thickness (EP) with respect to the body shell side , in particular with respect to a bodywork part , the volume (V) extending in the vertical direction over a height (H), in particular a height (H) that is equal or substantially equal to the diameter of the steered wheel , the volume (V) being delimited by an envelope (E), characterized in that the first width (L10) of the first door is smaller than the second width (L20) of the second door , in particular the second width (L20) of the second door is between 1.5 times and 2.5 times the first width (L10) of the first door , in particular the second width (L20) of the second door is approximately 2 times the first width (L10) of the first door , and in that in the open position (PO), the first door , in particular a vertical edge and/or a lower edge of the first door comes to be substantially tangential to the envelope (E) with a clearance (J) of between 10 mm and 40 mm. - a body shell side in which an opening is created, - a steered wheel which can occupy a volume (V) as the steered wheel changes direction, - a first door and a second door that are designed to close the opening , the first door and the second door being mounted so as to be able to move relative to the body shell side such that they are guided so as to each move substantially parallel to themselves during its opening and/or closing movements, the first door being arranged so as to open towards a first region of the of the body shell side that is intended to receive the steered wheel and the second door being arranged so as to open towards a second region of the body shell side that is intended to receive a non-steered wheel , characterized in that the first width (L10) of the first door is smaller than the second width (L20) of the second door , in particular the second width (L20) of the second door is between 1.5 times and 2.5 times the first width (L10) of the first door , in particular the second width (L20) of the second door is approximately 2 times the first width (L10) of the first door , and in that in the open position (PO), the first door , in particular a vertical edge and/or a lower edge of the first door comes to be substantially tangential to the envelope (E) with a clearance (J) of between 10 mm and 40 mm. <EOS>
