Tire Pressure Monitoring System TPMS
I was wondering if there is a way to recalibrate our TPMS. For example mine says I have 30 PSI on a certain tire and every external gauge I use shows I have 34-38(obviously I have tested a few). I know it may seem miniscule but I really would like for it to be accurate or at least closer. Any help would be greatly appreciated.

are you taking your mesurement when your tire are cold or just after you went for a drive??

I have done both. They seem to be consistently off by about 4 PSI.

Do you have a Discount or American Tire store in your area
they have the same TPMS remote reader that the dealerships use, it is just in a different outer case

Most large Chain type tires stores likely have the same tool

The tool is used for checking & setting the wireless set up used in TPMS systems

sounds like a faulty sensor (assuming you havnt used runflat) that stuff can show lower readings or clog sensors up completely
ive seen them come in and have to be reset because because of different reasons but never because there only "somewhat working"

I do have discount tire in the area I can take it to. I have never used the Fix a Flat stuff you are talking about. Are you saying I can go to Discount Tire and since they have the same system they can test and recalibrate my system if needed?

They did for mine & then did it again when i had changed to aftermarket rims
