Tire Pressure light after 30 miles-pressure OK

[weatherr]

My 04 G35X displays the low tire pressure indicator on the dash with no audio signal after about 30 - 35 miles traveled on the highway. The dash display will stay on from that point on until I turn off the ignition and then it will not reappear until I drive 30 - 35 miles again. The actual tire pressure has no effect on this. I would appreciate any ideas or mention of a similar experience. Thanks.

My car does the same thing. In and around town, no light. But once I get on the freeway about 25-30 miles or so.. Boom there it is. I was told that there is nothing wrong with my tires. Since I had them at 35 psi it was about 5psi over the factory setting. When the tires warm up the psi get higher hence making them a little over inflated. Thus triggering the sensor light. So i put them down to 30psi when cold and haven't had a problem. Since I live in Alaska (negative temps all the time) the days are starting to warm up and I had my tires changed over, and its back to old business. LOL! Its going into the shop monday for an oil change and a oil burning smell, so i'll have them mess with it. Hope this helps or at least helps you know there are others that feel your pain.

It could be a tire pressure issue or a sensor issue.

I had the same problem...I just pumped up the tires alittle above 31psi and never had the light come on again

No need for two threads on the same thing. Threads merged here.

I have tried 30 psi, 32 psi, and 35 psi.
No help.

Try getting the sensors reset at a reputable tire shop, or have the dealer do it. Shouldn't take more than a few minutes in a properly equipped shop.

Also, are you rolling on a spare? The spares don't have sensors and will keep the system lit.
