bought my jk not long ago nd checked my tire pressure the first time i was guna air down and go on the beach. it was at 45. the sticker on my car and on the inside of my door says it should b at 37. i put it at 37 to reduce ware on my tires(BF MUD TERRAINS) nd the low tire pres. light wont go off even after 16 miles? what should i do?? HELP

 

How far did you drive to the beach?

Make sure all tires are above 34psi or so.. if they "all are" try another gauge.

 

stockers are 37. sounds like the pressure gauge your using is way off.

 

Keep in mind your supposed to measure your tire pressure while the tires are cold. Driving generates heat in the tires and that heat causes an increase in pressure. Its perefetly normal and depending on how far you drove, temps, etc an 8psi increase is not out of reason. Next time you fill your tires make sure they are at ambient temperature (fill/check them after sitting for about 15 min if you have been driving).

Make sure to check your spare! One day my tire pressure light came on, I checked and the tires were at 37 all around so I was worried something was wrong. Luckily the JK's spare is on the back so I just checked it off hand and it was down in the 20s. I filled up the spare and no more light!

Ive driven a WJ with the TPMS and the spare is really tough to get to. Same thing happened with it and it was a 15 minute ordeal of accessing the valve stem of the tire under the trunk, getting the air hose in there, filling it up and putting everything back!

 

Must not be an option on my RUBICON. I air down to 12 psi with BFG Mud Terrains and i never get the tire pressure light.

 

im pretty sure its on 08's and newer

 

correct. the 07 did not have the tpms.
rubber valve stem- no tpms
metal valve stem- tpms

had it on my 08 patriot and during the winter months it liked to go off. really dont miss it on my rubi.

 

i just got the AEV procal and shut it off completely
