Review definitions, measurement principles, workshop procedures, diagnostic references, tables, diagrams and frequently asked questions prepared for professional equipment users.
Automated Tread Depth Scanning
How drive-over optical tread measurement works, what affects capture quality and why manual verification remains necessary.
5 min readTire Wear PatternsBoth-Shoulder Tread Wear
How to evaluate symmetrical shoulder wear, low-pressure history, loading, cornering duty and possible internal heat damage.
5 min readDamage and AgingTire Bulges and Impact Damage
How to recognize a localized bulge, inspect the wheel and suspension, and handle suspected internal cord damage.
5 min readTire Wear PatternsCenter Tread Wear
How to confirm center-dominant wear and investigate pressure, load, tire construction, wheel width and service duty.
5 min readInspection FundamentalsComplete Tire Inspection: A Systematic Workshop Procedure
A repeatable inspection sequence covering identification, pressure, tread depth, wear patterns, damage, aging and reporting.
5 min readTire Wear PatternsTire Cupping and Scalloped Wear
How repeating depressions relate to damping, balance, runout, looseness and alignment, and why the pattern has no single automatic cause.
5 min readDamage and AgingReading the Tire Date Code
How to locate and interpret the manufacturing date code and use age as context rather than a stand-alone approval decision.
5 min readDamage and AgingExposed Cord, Belt Separation and Tread Distortion
How to recognize reinforcement exposure, tread lifting, waviness and shape change that require a structural decision.
5 min readTire Wear PatternsTire Feathering and Saw-Tooth Wear
How to feel directional tread-block edges and connect lateral scrub to toe, thrust angle and suspension compliance.
5 min readTire Wear PatternsTire Flat Spotting: Temporary and Permanent Conditions
How to distinguish storage-related temporary shape set from lock-up abrasion, permanent runout and structural concerns.
5 min readInspection FundamentalsHydroplaning: Tire, Water and Speed
An engineering explanation of water evacuation, speed, pressure and tread condition without relying on a single universal threshold.
5 min readTire Wear PatternsInner-Shoulder Tire Wear
How toe, camber, ride height and suspension movement combine to create hidden inner-edge wear.
5 min readDamage and AgingTire Punctures and Repairability
A framework for locating penetrations, inspecting the inner liner and applying manufacturer repair-zone and damage criteria.
5 min readDamage and AgingSidewall Cracks, Weathering and Ozone Damage
How to inspect sidewall cracking and evaluate depth, location, bulging, cord exposure and environmental history.
5 min readDamage and AgingTire Aging, Storage and Service Life
How time, heat, oxygen, ozone, sunlight, storage and operating history affect tire condition even when tread remains.
5 min readAutomated InspectionTire Inspection Reports: Measurements, Evidence and Recommendations
How to turn tread values, pressure, images and technician findings into a clear, position-specific service record.
5 min readInspection FundamentalsTread Depth and Wet Grip
Why water-evacuation margin decreases as tread wears and how to explain remaining tread without reducing the decision to a legal minimum.
5 min readInspection FundamentalsTread Depth Measurement: Manual and Automated Methods
How to choose measurement locations, use a gauge correctly, interpret the minimum value and verify automated readings.
