[s-cars] tire wear on a lowered cars

[LL - NY]

Also consider toe-in. If the car is toed-in too much, the outside edges will
wear,
with some feathering (the overhanging "edge" would be towards the inside of
the car.) could explain the further uneven wear towards the middle section
of
the tread. Toe-out has the opposite effect (inside wear, with feathering).
 Had the latter issue on my 200Q post lowering and although I knew the toe
was out, I didn't have the time to remedy right away. 6 weeks later, I had
badly
worn tires. I've been told toe actually has a worse effect on wear than
camber.
