Can I replace the tires on my car with a lower speed-rated tire
When replacing
speed-rated tires, you must use
replacement tires with ratings equal to or greater than those of the
original equipment tires if the speed
capability of the vehicle is to be maintained. The handling of a performance
vehicle may be different when the replacement tires are not the same speed
rating. Refer to the vehicle owner's manual to identify any tire speed rating
restriction that could affect the operation of the vehicle.*
* Exceeding the legal speed limit is neither recommended nor endorsed.
