What does DOT code 1025 mean?

DOT code 1025 indicates the tire was manufactured during week 10 of 2025 (March). This tire is approximately 1.4 years old.

Is a 1.4-year-old tire safe to drive on?

A 1.4-year-old tire has a safety index score of 86%. The tire compound is safe for regular highway use.

Will DOT 1025 pass vehicle safety inspection?

A tire stamped DOT 1025 will pass annual vehicle inspections provided tread depth exceeds 1.6mm (2/32") and no visible sidewall bulges or deep cracks are present. However, compound hardening at 1.4 years affects wet stopping distance.

Where is the 4-digit DOT date code located?

The 4-digit DOT date code is stamped on the outer sidewall of the tire, immediately following the letters "DOT" and manufacturer plant codes.

REAL-WORLD IMPLICATIONS FOR DOT 1025

🏎️

INSPECTING USED VEHICLES

If inspecting a pre-owned vehicle fitted with DOT 1025 tires, note that you are looking at rubber manufactured 1.4 years ago. These tires are within their safe usable lifespan, provided tread depth exceeds 3mm.
