Nice try, but it sounds like the real concern is uneven wear which will cause increased stress and thus tire failure.
Uneven wear originates from footprint stress, displacement, and shear
energy differentials occurring in ordinary tire usage at moderate
operational conditions. The footprint behavior of a
typical performance tire and of a typical heavy duty radial tire have been
compared and contrasted in the realm of slip and inclination angles
occurring due to toe-in and suspension alignment camber. The
operation of the tires has been extended to modest lateral acceleration
conditions, less than 0.2g. Very detailed information on the normal
stress, lateral stress, longitudinal stress, lateral displacement, and
longitudinal displacement fields within contact are examined and certain
conclusions can been drawn:
1) Certain manufacturers will use different structures in developing their tires and when doing so it is indicated as such with an arrow or similar warning label.
2) Uneven camber is more likely to cause damage and early failure of tires than that of turning a radial inward.
