Low pressure sign

I just replaced my wheels with snow tires(pirreli) for my 2007 G35 coupe, however, the low pressure sign is not going off despite the air pressure is normal. Can anyone answer this problem? This is bothering…

I’m not sure how those low pressure things work but I’m gonna take a stab at it.
The size of those winters, are they the same? Are the offsets on your winter rims the same as the stock rims?
If they are bigger that may cause extra sagging even though they are fully inflated. If I’m correct Electronics experience here the low pressure tires indicator works on proximity sensors. There
But then again I could be all wrong. Was this sensor going off before the tire change?

My snow tires are 225/50/17 and they are the recommended size from the dealer and the sensor was off before the replacement.

the sensor was off the summer rims befor you switched to snow tires?
cause you need to re learn your tire pressures inorder to get rid of the light
