Hey all,
I got an '07 G Coupe back in October of '07 and well, like a month and a half ago my tire sensor lit up. I read the manual and I figured it was just low pressure on one of my tires. I checked them all out and they're all running on 40psi. The light turned off for about 2 days before it went back on again. To this day the tire sensor is still lit and I haven't got the slightest clue of what's goin on.

Any ideas?

 

sometimes the tpms do go crazy and the dealer has to recalibrate them. You should be running less than 40psi though. I think infiniti specs call for 30-33 psi depending on tire sizes.

 

I had that problem too. Took it into the dealer and they reset the light under warranty.

 

umm, it also lights up for anything over spec, which 40 psi seems a LOT for a car tire... is that what is recommended by the booklet/ manual?

 

40? Damn. G must feel like you riding your a$$ on the gravel.

bring it down to 35.

 

well im rolling on the stock 17's so i have beefy tires. the booklet says 35-40. so i tried 35 and the light didnt go off, and im trying 40 and it still hasnt gone off.

but i guess i'll try the dealership since im due for the first maintenance soon

 

Check out the owner's manual for your car.

It says that you should have 30 PSI on the stock 17s. You have way too much pressure in your tires.

 

by god dave, you may just have prevented my tires from blowing up. i must've gotten the psi's mixed up when i read it.

well...let's see if that works.

 

The cold weather could be messing with them as well...

 

Julio since you have an '07 take it in and have the stealership make the
adjustments needed to your TPS. Why would you put 40 PSI in your tires?
I believe the manual says 35 PSI, that's exactly what you should run. Running that kind of pressure in your tires should make driving horrible plus
it will make the life of your tires short!

 

Maybe the TPS senses over inflation as well? 40lbs is way too much air for any tire, except maybe a truck.

I know mine are very sensitive in the colder weather, and usually go off when the pressure drops a pound or two.

Maybe it does go off if there is too much air in the tire as well.....

 

what should my psi be in my 06 coupe on factory 19's... my light is on as well and i didnt know what it meant till reading this this thread...

 

It should tell you on the sticker on your drivers side door jam....I think anywhere between 32-35lbs should be fine. Key to this is to make sure all tires are inflated to the same PSI. If one is off alittle, it will trigger the light.

 

thank you, i will check out that sticker and then check the tires...

 

i have mine at 35psi...
