Tyre Codes Decoded: A, B, C, Speed Ratings, and Expiration Dates Explained for Safer Driving

• Tyre sidewall codes like 195/55 R16 87V, Traction A, and Temperature A, B, C provide crucial safety information often overlooked by buyers.
• Heat Resistance (Temperature A, B, C) indicates a tyre's ability to withstand heat from friction; Grade A is safest, especially for Indian climate.
• Traction Rating (AA, A, B, C) measures braking effectiveness on wet roads; AA and A offer superior grip and shorter stopping distances.
• Speed Symbol (L to Z) specifies the maximum safe speed a tyre can handle, with common passenger car tyres rated H (up to 210 km/h).
• A four-digit code (e.g., 2423) indicates the manufacturing week and year; experts advise against using tyres older than five to six years due to decreased grip and increased accident risk.

Why It Matters: Understanding tyre codes for heat, traction, speed, and expiration is vital for vehicle safety and performance.
