Newb question. How much pressure does a tire have to lose before it sets off the Tire Pressure Monitor warning light? The warning light on my wives 06 coupe went off this morning and I found one tire about 4 psi low. I filled all the tires to the same pressure and it is still on. Does it take a little while for the light to reset?

 

Yes it took mine about five minutes of freeway driving before it went off for me. The TPMS is very sesitive tho it drives me crazy...

 

I Think It Comes On At 30 Psi After You Put Air In The Tires It Takes 5 To 10 Min To Turn Off

 

Tires should be at minimum 35psi (Check the sticker on the door jam)...the tpms light should go away within 1/4 mile.

 

Mine went off at 22-23psi.

As said...light will eventually go out after psi's are back up and drive awhile.

35psi cold is the correct amount.

 

35 psi is what I have in them now.

 

should come on at 27 PSI with a nominal pressure system of 35 PSI.

 

Your guage could be inaccurate. Try another one & see if you get the same readings.

 

correct...I had a slow leak for awhile and light was coming on at 26-27..but after I filled to 35....light go off in 1min...I always waited for the light to go out...that damn alarm scared the **** out of me the first time...

 

mine went off at around 26 does it have anything to do w/ the weather?

 

Yes...at times the tpms will alarm in the morning and go away by noon due to the warmer temp and pressure building up. That's why it's best to check the tire's pressure the first thing in the morning before any driving.

 

Yes. We can get some quick moving low pressure systems thru here, and every time my sensors have gone off has been just after one of those storms. I was usually at about 30 psi in one or two tires.

 

what i usually do, i just try to fill it up slightly more than the max psi rating. when i did that, i never had any problems getting those pesky warning lights.

 

I put 34psi in the wife's coupe and it rides like ****. Put them at 31psi.

Here is the pressure sticker:

 

i keep mine at 46...
