<p>Tyre comprising a carcass reinforcement (60) and having an outer profile (200) such that, when the tyre is fitted to the mounting rim and inflated to its service pressure, in any radial section, the distance between the carcass and the outer profile reaches its minimum value (DM) at a first point (62) of the carcass having a radial height (HD) 0.50⋅Η≤HD≤0.75⋅Η, H being the radial height of the tyre; wherein the tangent (T) to the carcass at the first point forms an angle (β)≥5° and≤32° with the radial direction (R); wherein there is a first zone (Z1) of the carcass, comprising the first point, such that the radius of curvature RCC of the carcass is less than the radius of curvature RCO of the outer profile (RCO > 1.2⋅RCC); wherein there is a second zone (Z2) of the carcass radially inside the first zone, such that RCO < 0.9. RCC, each second-zone point having a radial height≥0.40⋅Η.</p> |
