Correct answer
wear more at the sides.
When tyres are underinflated, they wear more at the sides. This is because insufficient tyre pressure causes excessive deformation of the sidewalls, which makes the edges of the tread (known as the shoulders) have greater contact with the road. As a result, these tread edges wear faster than the centre, which reduces the tyres' lifespan and decreases their efficiency. Therefore, maintaining the correct inflation pressure in the tyres is essential to ensure even wear and extend the tyres' lifespan.
