Title:
【発明の名称】自動車およびそれに用いる前輪用と後輪用の空気入りタイヤの組み合わせ
Document Type and Number:
Japanese Patent JP3064271
Kind Code:
B2
Abstract:
A vehicle having an Anti Lock Brake System (ABS) and front tyres (2R,2L) and rear tyres (3R,3L) which are capable of providing maximum braking effect when the ABS is in operation, each of the tyres comprising a plurality of tread elements (6) divided by tread grooves (5) , and the tread pattern rigidity Pr of the rear tyres (3R,3L) is more than the tread pattern rigidity Pf of the front tyres (2R,2L), wherein the tread pattern rigidity P (Pr, Pf) is defined as a quotient of the total of circumferential rigidity of all the tread elements (6) existing in a ground contacting region of the tyre divided by the area of the ground contacting region, and the circumferential rigidity K of each tread element is defined as a quotient of a tangential force F in kgf received at the ground contacting region which is divided by a displacement y in mm at the ground contacting region.
