The tire size for the 2000 Pontiac Grand Prix varies slightly with the model of the vehicle. The average tire size is 225/60 R16.
P225/60R16 is the proper factory tire size.
225 60 16
how do you reset the tire pressure warning light on a 2004 pontiac grand prix
The tire size should be P225/60R16. To verify the tire size there is a Tire Information Label on the inside of your trunk lid.
I own a 2004 Pontiac Grand Prix GT2 and the Corect tire size is 225/60/R16 and all four tires should have 30 psi tire pressure at all times for a smooth and comfortable ride.
