RIf the size description of your tire includes
"ZR" and there are no service
specifications, ask the tire manufacturer in
order to find out the maximum speed.
G Warning
Even when permitted by law, never operate a
vehicle at speeds greater than the maximum
speed rating of the tires.
If a service specification is available, the
maximum speed is limited according to the
speed index in the service specification.

example, "97Y" is the service specification.

Exceeding the maximum speed for which tires
are rated can lead to sudden tire failure,
causing loss of vehicle control and possibly
resulting in an accident and/or serious
personal injury and possible death, for you
and for others.
