Then why are they *required* by law on all US automotive tires and wheels?
There is no such requirement.

Motor magazine article on match mounting for aluminum wheels:
http://www.motor.com/article.asp?article_ID=1304

"OE tire suppliers are *required* to mark a tire’s radial runout
high point, and OE wheel makers are *required* to mark a wheel’s
radial runout low point."

Tire Rack article on match mounting:
http://www.tirerack.com/tires/tirete....jsp?techid=17

"Original Equipment (OE) tire suppliers are *required* to mark the
tire's "high point" while OE wheel manufacturers mark the wheel's
"low point."



Notice the OE and OEM? This is required ONLY on tires and wheels sold
to auto manufacturers to be installed as the vehicles are made.

Look at tires that are not sold as an OEM tire and you usually won't
find marks. Especially on house brands and LT tires.
