Tyre wear means the gradual loss or damage of the tyre tread and rubber during vehicle operation due to contact with the road.
For a truck, every rotation of the tyre creates friction between the tyre tread and road surface. Over time, the tread becomes thinner or develops an abnormal wear pattern.
For a Truck Field-Quality Investigation
I would group the causes into 5 major categories:
1. Tyre
Pressure, tyre specification, tyre quality, tread depth, retread condition.
2. Wheel/Rim
Rim punching, rim sinking, rim runout, wheel imbalance, wheel mounting.
3. Axle & Suspension
Axle alignment, suspension bushes, springs, shock absorbers, wheel bearing.
4. Vehicle Operation
Overloading, braking, acceleration, wheel digging, cornering and driving pattern.
5. Road Environment
Potholes, rough roads, mud, sand, gravel and road camber.

Factors Affecting Tyre Life
Following are the various factors affecting tyre life, to be considering
during root cause establishment:
| Issue / Condition | Typical Cause | Effect on Tyre | Typical Tyre-Wear Pattern | Severity / Relevance |
|---|---|---|---|---|
| Wheel Digging | Wheel spin, high torque, soft/muddy terrain, high load | Sliding between tyre and road | Rapid tread/localized wear | High |
| Rim Punching | Pothole, kerb/stone impact, severe shock load | Rim deformation affects tyre seating | Irregular wear, possible bead damage | Medium–High |
| Rim Sinking | Severe impact, overload, wheel deformation | Changes wheel geometry/runout | One-sided/irregular wear | High |
| Low Tyre Pressure | Leakage, incorrect inflation, poor pressure maintenance | Excessive tyre deflection and heat | Shoulder wear | Very High |
| High Tyre Pressure | Over-inflation, incorrect pressure setting | Reduced contact area | Centre tread wear | High |
| Wheel Alignment Error | Incorrect toe/camber, axle misalignment | Tyre scrubbing against road | One-sided / feathered wear | Very High |
| Wheel/Rim Runout | Bent/deformed rim, improper mounting | Uneven rotation | Cupping / irregular wear | High |
| Wheel Imbalance | Uneven tyre/rim mass, improper balancing | Repeated vertical vibration | Cupping / scalloping | Medium–High |
| Axle Misalignment | Rear axle/thrust-angle issue, suspension geometry | Tyre is forced to run at an angle | Diagonal / one-sided wear | Very High |
| Suspension Problem | Worn/damaged spring, bush, shock absorber, U-bolt etc. | Uneven wheel loading | Irregular/cupping wear | High |
| Overloading | Excessive vehicle/axle load | Increased tyre deflection and heat | Rapid overall wear, shoulder wear | Very High |
| Over-Braking / Brake Drag | Brake adjustment or brake component issue | Excessive heat and sliding | Localized/rapid wear | High |
| Wheel Locking | Aggressive braking, brake imbalance | Tyre slides instead of rolls | Flat spot | High |
| Differential / Driveline Issue | Torque imbalance or driveline problem | Uneven wheel torque/slip | Irregular drive-axle wear | Medium–High |
| Tyre Overheating | Low pressure, overload, high speed, high ambient temperature | Rubber degradation | Accelerated wear, cracking | High |
| Incorrect Tyre Fitment | Wrong tyre size/specification or application | Incorrect load/contact characteristics | Abnormal/accelerated wear | High |
| Mixed Tyre Sizes / Tread Depths | Incorrect tyre pairing | Different rolling circumference | Uneven wear, driveline stress | Medium–High |
| Retread / Tyre Quality Issue | Poor retread bonding, casing condition, manufacturing defect | Abnormal tread behaviour | Localized/irregular wear | Medium–High |
| Road Condition | Potholes, rough roads, gravel, uneven surfaces | High impact and abrasion | Irregular/rapid wear | High |
| Driving Behaviour | Harsh acceleration, cornering, braking, overspeeding | Increased slip and lateral forces | Rapid/irregular wear | High |
| Cornering / Lateral Scrub | Sharp turns, high-speed cornering | Lateral sliding of tyre | Shoulder/edge wear | Medium–High |
| Tyre Rotation Issue | Rotation not performed when required | Uneven wear remains concentrated | Progressive uneven wear | Medium |
| Improper Wheel Nut Torque | Under/over-torquing, incorrect tightening sequence | Wheel seating/runout problems | Irregular wear + safety risk | High |
| Wheel Bearing Issue | Excessive play/preload, bearing damage | Wheel movement/runout | Irregular/one-sided wear | High |
| Valve/Air Leakage | Damaged valve, bead leak, puncture | Gradual pressure loss | Shoulder/overall accelerated wear | High |
