In a radial tyre, which two areas behave more independently because of its construction?

Correct answer

The tread and the sidewalls

The tread and sidewalls. Radial construction combines a reinforced tread area with flexible sidewalls. They are not separate pieces, and this does not mean every impact causes negligible deformation: impacts can damage a tyre, so have it checked if abnormalities appear.
