The table below shows
the maximum speed tires are rated to perform at according to their
markings on the sidewall. If you are replacing tires on a vehicle, be
sure to purchase a tire rated as high or higher than the original tires
that were sold when the vehicle was new. Any tire with a lower rating
may produce unexpected handling results and degrade performance of both
the vehicle and the tire. It could also be unsafe. |
