Note: Legal minimum tread depth is 2/32" in most US states. New tires typically have 10/32" to 12/32" of tread. Aggressive driving, alignment issues, and under-inflation accelerate wear.
Reference
Wear Rate = Miles Driven / (Initial − Current) tread
Remaining Tread = Current − Minimum Legal
Remaining Life = Remaining Tread × Wear Rate
Percent Worn = Tread Used / (Initial − Min) × 100
