b.Loss of directional stability

d.Rapid center-tread wear
解析
Positive caster tilts the steering axis rearward at the top, improving straight-line stability and steering return but increasing effort. Too little caster causes wander and poor return. Caster is measured during alignment and typically compared side to side.
