FIELD OF INVENTION This invention relates to automobile and more particularly this relates to spare wheel and tire mounting arrangement. BACKGROUND OF INVENTION All automobiles are required to have spare wheel and tire in case of eventualities. Conventionally spare wheel and tire are mounted underneath the vehicle chassis or in a well provided on floor or on tail gate of vehicle. The drawbacks associated with said mounting arrangements are that in some cases said spare wheels are not easily accessible and requires more space; and in some cases heavy reinforcement is required to properly mount the same. Another drawback is that most of the conventional spare tire mounting arrangement does not provide an easy and ready disengagement provisions. US 3610678 teaches spare wheel mounting clamp, wherein spare wheel is positioned within the well with the wheel axis normal to the well walls. A clamp includes first and second hinged clamp members. The first clamp member has an end portion engageable with the inner wall. The second clamp member has an end portion engageable with a jack base positioned on the wheel on the side thereof facing the inner wall. The clamp members move between an initial portion and an overcenter clamping position forcing the spare wheel against the outer wall to thereby mount the spare wheel within the well. Stops on the first and second clamp members cooperate to prevent movement of the clamp members past the overcenter clamping position. The drawback associated with the said prior art is that this arrangement is not able to effectively utilize the boot space, very much complex for fitment/removal. OBJECTS OF INVENTION The main object of this invention is to provide spare wheel mounting arrangement for automobile with effective utilization of boot as well as well space. Another object of this invention is to provide spare wheel mounting arrangement for automobile which is able to provide an additional stiffness to BIW. Yet another object of this invention is to provide spare wheel mounting arrangement for automobile which is able to have good accessibility along with easy to mount/demount. Yet another object of this invention is to provide spare wheel mounting arrangement for automobile which is able to effectively distribute the load to floor as well as to mounting means. Yet another object of this invention is to provide spare wheel mounting arrangement for automobile which is having good NVH characteristics. Yet another object of this invention is to provide spare wheel mounting arrangement for automobile which is simple in construction and cost effective. BRIEF DESCRIPTION OF INVENTION Spare Wheel mounting arrangement in accordance with this invention basically comprises of at least one cross member, spare wheel mounting assembly, mounting means for cross member, dampening means and spare wheel. Said spare wheel mounting assembly comprises of mounting bracket which is rigidly fixed to said cross member, preferably said bracket is rigidly fixed to said cross member at an angle, clamping plate and one or more fasteners. Wherein said cross member is rigidly fixed to shock absorber towers through mounting means for cross member. Said dampening means are provided on said cross member to arrest shocks and vibrations, said spare wheel is mounted on said mounting bracket through clamping plate and fastener. Before clamping it is necessary to ensure that the spare wheel rests on dampening means and floor. As the spare wheel is fastened on to the cross member at an angle and rests on the flexible mounts and floor, it provides a sliding arrangement for the spare wheel and effective load distribution. As the cross member is continuously running from one side shock absorber tower to the other, providing BIW stiffness and good NVH characteristics. BRIEF DESCRIPTION OF DRAWINGS Fig. 1 shows spare wheel mounting arrangement provided in vehicle in accordance with this invention. Fig.2 shows front view of spare wheel mounting arrangement Fig.3 shows mounting bracket and dampening means provided on cross member Fig.4 shows fitment of cross member to the shock absorber tower Fig.5 shows the side view of spare wheel mounted on cross member Referring to the Figs.l to 3, spare wheel mounting arrangement consists of a cross member (3) connected to the shock absorber towers (2) through cross member mounting brackets (6a, 6b), shock absorber towers (2) are connected with floor (9), the spare wheel (1) rests on floor (9) and dampening means (8), and is fixed to the mounting bracket (7) through clamping plate (4) and Fastener (5). Referring to Fig. 4, cross member mounting brackets (6a, 6b) connects the cross member (3) and shock absorber tower (2). Said cross member mounting brackets(6a, 6b) are welded to the shock absorber towers (2) at one end and other ends are fastened to the cross member (3). DETAILED DESCRIPTION OF THE INVENTION Referring now to the drawings wherein the showings are for the purpose of illustrating a preferred embodiment of the invention only, and not for the purpose of limiting the same. Now referring to Fig. 5, Spare wheel (1) is mounted on mounting bracket (7) through clamping plate (4) and fastener (5) at an angle. The spare wheel is fastened on to the cross member (3) at an angle and rests on the dampening means (8) and floor (9), it provides a sliding arrangement for the spare wheel and effective load distribution. As the cross member (3) is continuously running from one side shock absorber tower (2) to the other, it provides BIW stiffness and good NVH characteristics. The foregoing description is a specific embodiment of the present invention. It should be appreciated that this embodiment is described for purpose of illustration only, and that numerous alterations and modifications may be practiced by those skilled in the art without departing from the spirit and scope of the invention. It is intended that all such modifications and alterations be included insofar as they come within the scope of the invention as claimed or the equivalents thereof. WE CLAIM 1.
