Correct answer
The tyre's deformation and fuel consumption increase.
When driving with insufficient tyre pressure, the tyres wear more and more unevenly, because wear occurs more on the sides than in the centre of the tyre. In addition, a tyre with excessively low pressure increases fuel consumption. In the case of over-inflated tyres, wear occurs in the centre.
