Should we check the inflation pressure of the spare wheel before going on a trip?
Travel: Preventive and efficient driving
Explanation
Spare wheel: pressure and tread before travelling
- Before a long trip, check the **inflation pressure** of all tyres **when cold**, including the **spare**.
- Also check the **tread pattern** and **tread depth** (legal minimum: **1.6 mm**). Insufficient tread reduces grip and increases the risk of aquaplaning.
- Measuring **when cold** (vehicle stationary and not yet driven) ensures an accurate reading; when hot the pressure rises and can be misleading.
- The spare loses air over time; if it isn’t in good condition, it won’t be of any use in an emergency.
