What causes abnormal tire noise?

[SanTimothy]

Abnormal noise from car wheels indicates potential malfunctions that require prompt inspection and troubleshooting to ensure driving safety. Common causes of wheel noise include: 1. A rhythmic clicking sound that varies with vehicle speed - usually caused by stones or nails puncturing the tire; (1) For stones, simply remove them with appropriate tools; (2) For nails, visit a repair shop promptly for tire patching if there's no air leakage. 2. Metallic scraping sounds - more noticeable during braking, indicating worn brake pads that need immediate replacement. 3. Clunking noises - particularly evident during acceleration/deceleration or steering, possibly accompanied by body sway when severe. This suggests loose bolts that require immediate inspection for potential damage to bolts or bolt holes. 4. Increased tire noise - typically caused by excessive tire pressure. Overinflation not only increases noise but also stiffens suspension, reduces shock absorption, makes steering overly light, and compromises tire grip. Simply adjust tire pressure to standard values in such cases.
