Tire Tread Wear & Abrasion Metrics
TreadSight™ Tire Wear testing programs are built on traceable tread depth measurement and cycle based trending. Where additional insight is required, abrasion efficiency indicators are included to support compound comparison and material usage interpretation under real-world service conditions.
Core wear measurements
-
Tread depth trending
Cycle by cycle changes tracked across defined test cycles. -
Wear rate reporting
Reported in imperial and SI units as defined by program requirements. -
Traceable measurement context
Tire identification, cycle tagging, and program context support defensible engineering review.
Abrasion efficiency indicators
iTAS™ and mTAS™ are provided as additional abrasion efficiency indicators, these indicators complement tread depth based wear rate reporting.
-
iTAS™
An internally derived abrasion efficiency indicator expressed in imperial units. -
mTAS™
An internally derived abrasion efficiency indicator expressed in SI units. -
Mass based context (when included)
Tire mass change tracking adds a material loss perspective alongside depth based wear measurements.
Why multiple views matter
Two tires can show similar tread depth wear yet differ materially in rubber usage efficiency. Pairing depth based trending with abrasion efficiency indicators supports clearer interpretation of compound behavior, wear progression, and comparative abrasion performance under real-world operating conditions.
Note: Metric definitions and reporting scope are defined per program and test type. Abrasion efficiency indicators are reported within Dedicated Testing programs. Underlying calculation methodology and data collection processes remain proprietary.
