Resetting the TPMS
« on: August 29, 2018, 06:17:48 pm »
I was recently on a trip and ended up with a nail in my rear tire.  After plugging it, I noticed that the tire pressures read lower than the actual.  (checked with a few different pressure gauges).  Is there a way to recalibrate the TPMS sensors?  Any assistance would be greatly appreciated.

sorry, not there is not.
whatever it reads, is just a close proximity to actual pressure via gauge.
It does change, and goes up, as the tire heats up tho, but it's relative to the actual changes you would see using a gauge in the same situation.
Pretty much they are within a couple p.s.i. of the true pressure, around a 5% deviation (maybe + or - 3psi)
It was never designed to replace a tire gauge, so keep that in mind, and if you check with a gauge, and you have 40 psi, and begin riding (a couple hundred feet) and check the meter (and it shows 38, or 42), you can pretty much keep that relationship memorized.
The main function is to warn you if rapid deflation is occurring,(the warning appears at, or when pressure drops to 32 psi, or below, (as sensed by the TPS in rim) and should not appear when pressure is above 33 psi) before dangerous conditions make safety an issue, that is all... and it does work for that single purpose.

If the TPS is reading lower than the actual gauge readings you have, you actually have an additional margin of safety, and thats a good thing... :great:
