Causes
Root causes for torque steer are:
- Incorrect sidewall ply design allowing deformation of the tire sidewall.
- Asymmetric driveshaft angles due to any combination of
- Unequal driveshaft length or diameter
- Transient movement of the engine
- Tolerances in engine mounts
- Body roll
- Single wheel bump
- Different driveshaft torques left to right (due to wheel bearing or differential problems)
- Suspension geometry tolerances
- Unequal traction forces due to road surface (ยต-Split) in combination with kingpin offset
