Use a tread depth gauge for accuracy. Also, check for any visible cuts, lumps, or bulges which can deem a tyre unsafe. Regular inspections help ensure your vehicle remains safe and compliant with road safety regulations. If unsure, consult a professional tyre service for a comprehensive evaluation.
