TECHNICAL FIELD
[0001] The present subject matter relates, in general, to vehicle tires
and, particularly, but not exclusively, to non-pneumatic vehicle tires.
BACKGROUND
5 [0002] Tires support the load of a vehicle and impact handling,
drivability, and safety of the vehicle.
[0003] A tire is mounted on a wheel’s rim to transfer a load of the vehicle
from the axle through the wheel to the ground and to provide traction on
the surface over which the wheel travels.
10 [0004] Most tires, such as those for automobiles and bicycles, are
pneumatically inflated structures filled with air, which provide a flexible
cushion that absorbs shock when the tire rolls over uneven surfaces. Tires
provide a footprint, called a contact patch, that is designed to match the
weight of the vehicle with the bearing strength of the surface that it rolls
15 over by providing a bearing pressure that will not deform the surface
excessively
I/We Claim:
1. A tangential non-pneumatic tire (100) comprising:
an inner band (106) to interface with a rim (104) of a wheel on which
the tire (100) is to be mounted;
5 an outer band (108) separated from the inner band (106) and
forming a tread portion of the tire (100);
an array of spokes (102) extending in a circumferential and radial
direction of the tire (100) between the inner band (106) and the outer band
(108), wherein each spoke in the array of spokes (102) comprises:
10 multiple circular rings placed adjacent to each other and
connected about their circumference so that centres of the multiple circular
rings form a notional circle; and
wherein at least two of the spokes in the array of spokes (102) is
placed laterally and offset to each other along the width of the tire (100).

2. The tangential non-pneumatic tire (100) as claimed in claim 1,
wherein the outer band (108) comprises a tread layer (110), an under-tread
layer (112), and a belt layer (116), wherein:
the tread layer (110) contacts with a surface during
