If  you ever replace your tires  with those not having  a 
TPC  Spec  number, make sure  they are the same size, 
load range,  speed rating and construction type (bias, 
bias-belted  or radial)  as your original tires. 
A CAUTJN: 
Mixing  tires could  cause  you to lose  control  while 
driving. 
If you  mix  tires of different  sizes or types 
(radial  and  bias-belted  tires),  the vehicle  may  not 
handle  properly,  and you  could  have  a  crash. 
Using  tires 
of different  sizes  may  also  cause 
damage to your  vehicle.  Be sure  to use the same 
size  and  type  tires  on all  wheels. 
It’s  all right  to drive  with your  compact  spare, 
though. 
It was  developed  for use  on your  vehicle. 
Uniform  Tire  Quality  Grading 
The following information relates to the system 
developed  by the United States National Highway 
Traffic Safety Administration, which grades tires  by 
treadwear, traction and temperature performance. 
(This 
applies only to vehicles sold  in  the United States.)  The 
grades  are molded  on the sidewalls  of most passenger 
car  tires.  The Uniform Tire Quality Grading system does 
not  apply  to deep tread, winter-type  snow tires, 
space-saver  or temporary use spare tires, tires with 
nominal rim diameters  of 
10 to 12 inches (25 to 30 cm), 
or  to some limited-production  tires. 
While the tires available on General Motors passenger  cars and light trucks may vary with respect to these 
grades, they must  also conform to Federal safety 
requirements  and additional General Motors Tire  Performance Criteria (TPC) standards.
