ESTIMATION METHOD OF ABRASION STATE OF TIRE

PURPOSE:To obtain an estimation method in which the state of an abrasion which is generated on a tire tread, especially an irregular abrasion, is estimated simply and precisely. CONSTITUTION:The surface of a tread part 5 for a tire is coated, regularly in a grid shape, in a mesh shape or in a dot sh...

Zusammenfassung:	PURPOSE:To obtain an estimation method in which the state of an abrasion which is generated on a tire tread, especially an irregular abrasion, is estimated simply and precisely. CONSTITUTION:The surface of a tread part 5 for a tire is coated, regularly in a grid shape, in a mesh shape or in a dot shape, with a paint whose brightness difference from the surface of the tread part is large and which is deformed by following the deformation of the surface of the tread part. After that, the tire is rolled under a load on the surface of a road, and the generation state of an abrasion is estimated on the basis of the worn degree of the paint.
