The tyre has been used under-inflatedThis was the right answer

If you don't keep your tyres inflated to the recommended pressure, they may wear unevenly. Over-inflated tyres will tend to wear heavily in the centre tread area, while under-inflated tyres will tend to wear more on their outer edges. Check your tyres regularly and use a reliable gauge. Follow the manufacturer's guide for the correct tyre pressure; check and adjust the pressure when the tyres are cold.
