While not *over* 200mph, this is close.
(Y) rated - tested to 186+mph

Seeing as there are cars that can and will do 200+, it would stand to
reason
that there are tires built for them.

BFG "Z" rateds are for 149 plus. "Y" is for not over 186.


From the link above:
"When Z-speed rated tires were first introduced, they were thought to
reflect the highest tire speed rating that would ever be required, in excess
of 240 km/h or 149 mph. While Z-speed rated tires are capable of speeds in
excess of 149 mph, how far above 149 mph was not identified. That ultimately
caused the automotive industry to add W- and Y-speed ratings to identify the
tires that meet the needs of new vehicles that have extremely high top-speed
capabilities"


further:
"Most recently, when the Y-speed rating indicated in a service description
is enclosed in parenthesis, such as 285/35ZR19 (99Y), the top speed of the
tire has been tested in excess of 186 mph, 300 km/h indicated by the service
description as shown below:"
