Damage or pressure loss can be missed if only the outer tyres are inspectedThis was the right answer

Inspect every tyre for tread and sidewall damage and check its pressure. Inner tyres can be less visible, so looking only at the outside is insufficient. Do not infer tyre condition from the number of axles or how the coach feels.
