<p>A tyre comprising a carcass a ground 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), 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 % 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).</p> |
