1. Tire Wear and Tread Design
By Chris Klobedanz
MANE-6960

2. Primary Causes of Wear Physical properties of surfaces Tire design
Terrain
Improper setup of tire, wheel, or axle
Environment

3. Tire Components
Tread
Sidewall
Beads
Belts
Ply
Inner Liner

4. Tread Features
Blocks
Grooves
Rib
Sipes
Shoulder

5. Tread Pattern Designs Symmetrical – Most Common, long-lasting
Asymmetrical – Better handling and weather capability
Unidirectional – Best all-weather

6. Surface Description
Microtexture vs. Macrotexture:
Hardness
Polishing

7. Tire-Road Interface RW = A∗EF 𝑉 =𝐾 𝑃𝐴 𝐻 𝛾 Pacejka’s Magic Formula:
𝑉 =𝐾 𝑃𝐴 𝐻 𝛾
Pacejka’s Magic Formula:
R(k) = d∗sin(c∗arctan(b(1−e)∗k + e∗arctan(bk)))

8. Tread Wear Patterns Improper Air Pressure Balance Issues Wheel Damage
Alignment Issues

9. External Factors
