Patent ID: 6843291

Claim:
A vehicle tyre comprising a carcass extending between two wheelrim-contacting bead regions through sidewall regions and aground contacting tread region and a tread reinforcing breaker disposed radially outward of the carcass in the tread region, the tread region having inboard and outboard tread regions each extending between the tread circumferential centreline (X) and axially spaced-apart inboard and outboard tread edges (IE,OE), the inboard tread edge (IE) for mounting nearest to the vehicle longitudinal centreline, the tyre characterised in that in the condition that the tyre is mounted on its scheduled wheelrim and inflated to its scheduled pressure, the axial width (LR) of the tread between its tread edges (OE,IE) is not less than 75% 80% of the maximum tyre width (G), the axial width (LC) of the breaker is not less than 97% of the tread width (LR) and the difference in the breaker width (LC) and the tread width (LR) is not more than 25% of the difference between the maximum tyre width (G) and the tread width (LR), the tyre in addition characterised in that for the inboard tread edge only, axially outwards in the shoulder region between the tread edge (IE) and the adjacent sidewall, there is an axially Projecting hump ( 6 ) having a radially outer surface which is radially inward of the tread surface such that the hump ( 6 ) does not contact the ground in use of the tyre and the axial edge of the breaker on the side of the inboard tread edge (IE) is disposded within the hump ( 6 ).
