PURPOSE:To eliminate unbalance of the moment of a tire at the time of acceleration or braking where a spare tire having a diameter smaller than that of a normally used tire is mounted by setting a wheel offset amount for the spare tire. CONSTITUTION:An end of a driving shaft 20 is fitted into a axial shaft part of a knuckle member 21, and a shock absorber 22 and a lower arm 23 are connected to the knuckle part 21. The tire 24 is connected to a bolt 27 an a hub member 26 at a position spaced in the axial outward direction from the center line O of the width of the tire by an amount of d. Accordingly, when mounting a spare tire to a vehicle, the offset amount d' for the spare tire is determined by adding an amount x to the offset amount d for the normally used tire, and the spare tire is mounted to the vehicle with the offset amount d' from the hub member 26, while inwardly spacing the center line O' of the width of the spare tire from the center line O by the amount of x. |
