I put the GXP'* off my 96 onto my 2000 SLE and now the Check Tire Pressue message wont leave the DIC. We have the tires at the pressure stated on the tires. Any ideas?

Do you have run-flat tires on the GXP rims?

first off, your tire pressure should NOT be set to the pressure on the sidewall, you should probably be running 35psi with your setup.

second off, reset the tire pressure light. turn the key on with the engine off and hold the reset tire pressure button for what seems to be far too long ( its about 15 sec )

come back and well look into it farther if the light comes back on after that

10-4. I will try to reset it after work. If that doesnt help, we will reduce the pressure in the tires. I do not think they are run-flats, just the Eagle RS-A'* that came stock on the rims.

Just so I know, why would I want to lower the PSI?

becuase the rating on the side of the tire is a MAXIMUM rating for the tire itself, and has nothing to do with what will be the best for your specific car, and using an improper pressure will greatly affect drivability and tire life.

just some further info - The low tire pressure light does not come on because one tire is low on pressure the car has NO idea how much air is in the tire. It works by the sensors detecting wheel speed, and when one wheel is turning slower than the others would indicate a low tire pressure, this is why the light can come on for various reasons, like on snow/ice.

Cold inflation pressure is 30 psi all 4 tires, add 4 psi for hot pressures. This info is pasted on the driver door.

i quoted 35psi, based on the change in tire size, and the added performance potential of the 18s

Well, I reset it and it said "tire pressure normal" and went away. Thanks for all the info. I didnt get an owners manual with the car, so I may have more questions like this till I can get one....

glad we could help!

Sheesh, I forgot the GXP wheels are 18".
