Abstract
A radial tire when mounted on a rim and filled to normal inner pressure has a ratio of the upper cross-sectional height USH to the cross-sectional height SH between 0.50 and 0.59, a ratio of the lower cross-sectional height LSH to SH between 0.40 and 0.50, a rim width of more than 1.40 times the measuring rim width MRW but less than 1.45 MRW, an aspect ratio of less than 0.65, a beadfiller height of greater than 0.224 SH, and an angle between the tangent to the carcass line at a bead upper point B and a line extending in parallel with the rotation axis of the tire is less than 45°.
Claims5
A radial tire capable of being mounted on a rim and filled to normal internal pressure such that the ratio of upper cross-sectional height USH to cross-sectional height SH is between 0.50 to 0.59;
- the ratio of lower cross-sectional height LSH to cross-sectional height SH is between 0.40 and 0.50;
- the rim width is more than 1.40×measuring rim width and less than 1.45×measuring rim width;
- the aspect ratio is less than 0.65;
- the beadfiller height is greater than 0.224×SH;
- the angle between the tangent to the carcass line at a bead upper point (B) and the line extending in parallel with the rotation axis of the tire is less than 45°.
A radial tire as claimed in any preceding claim formed so that αthe angle between line CP in parallel with the rotation axis of the tire and a tangent to the carcass line at a point A on the beadfiller inner line AE, is less than 72° and β, the angle between line CP in parallel with the rotation axis of the tire and line CD, is less than 56°.
