Tire Wear and Tread Design By Chris Klobedanz MANE-6960
Primary Causes of Wear Physical properties of surfaces Tire design Terrain Improper setup of tire, wheel, or axle Environment
Tire Components Tread Sidewall Beads Belts Ply Inner Liner
Tread Features Blocks Grooves Rib Sipes Shoulder
Tread Pattern Designs Symmetrical – Most Common, long-lasting Asymmetrical – Better handling and weather capability Unidirectional – Best all-weather
Surface Description Microtexture vs. Macrotexture: Hardness Polishing
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)))
Tread Wear Patterns Improper Air Pressure Balance Issues Wheel Damage Alignment Issues
