2007 Chevy Avalanche loss air pressure all tires - 1/15/2008 7:00:14 AM

I just bought a 2007 Avalache LT with 20" stock rims. The truck had 900 miles and now has 1500 miles. So, I have put 600 miles on the car.

All four of the stock Bridgestone / Firestone tires seem to be lossing air and a very fast rate. The loss is not even. The front losses about a pound and a half a day and the back about a pound a day.

Has anyone else seen this issue? Any ideas of why this maybe happening?

Friday I filled the front tires to 33 lbs and the rear to 35 lbs. Today they are 30/29 front and 32/33 in the back.

I am going to do a very close inspection of my tires but was wondering if this was an issue others have had.

Thanks

More info:

When that car starts up the tire pressure is equal in all tires but as I drive it slighlty increases but becomes unbabalnced. Anyone know how accurate the tire pressue sensors are?

The tire pressure will change as the tires heat and cool and as such the pressure sensor will show differing amounts as the actual tire pressure is affected by tempature. As far as leaking, you should have them checked for defective stems and to ensure they were seated properly. Have it check by the dealer, It should still be under warranty regardless. 07 has 3/36 bumper to bumper including tires.
