heeeey all i have a problem i think.....ive been keeping track of my tire pressure this week and one of the rear tires is consantly around 8-10 psi lower than the other tire.....(idk which, whichever is the bottom tire pressure on the dash guage)...and i chk the pressure every morning and when i get home, so cool and heated, and the cool state its about the same....but when heated such as when driving....theres that gap again.....so should i add air? or go to the dealership? or wha?

 

Bottom is usually the left/drivers side.

Are you checking pressure with a gauge or just going by the reading on the TPMS?


Nail in tire?
Leak at bead?

 

The tire has a slow leak.

 

Does anyone out there know how to defeat the TPMS ?
Am considering another set of wheels for the winter and plan to run them without the sensors and all the same size vs the staggeered size it calls for...

 

You're confusing TPMS and VDC. TPMS is the tire pressure monitoring. If you run wheels without the sensors, then the system won't display pressures. After driving on them for about 45 minutes, the warning will sound and the (!) light will stay on. It doesn't do anything but that.

If your car has TCS or VDC and you run non-staggered sizes, then that will trigger the TCS/VDC. You have to drive with the TCS/VDC off button pressed to keep it from kicking in.
