Match each tyre condition or maintenance practice with its correct safety consequence or legal requirement.
- Under-inflated tyresCauses excessive wear on outer tread edges and increases fuel consumption
- Tread depth below 1.6 mm across the central three-quartersMakes the vehicle illegal to drive and increases stopping distance in wet conditions
- Fitting a space-saver spare wheelSubject to strict temporary use and a maximum speed restriction of 50 mph
- Checking tyre pressure before driving when tyres are coldProvides an accurate baseline reading unaffected by heat from driving friction
Answer
Under-inflated tyres pair with excessive outer tread wear and increased fuel consumption; tread depth below 1.6 mm pairs with illegal operation and increased wet stopping distance; a space-saver spare wheel pairs with temporary use and a 50 mph speed limit; cold pressure checks pair with accurate readings unaffected by driving heat.
Each maintenance rule and condition directly dictates specific physical and legal outcomes: under-inflation increases shoulder wear, tread depth below 1.6 mm breaches statutory safety rules, space-savers carry strict speed limits, and cold checks give true pressure readings.
