After getting my 20" wheels put on at the begining of the summer ive noticed whenever i drive my truck for longer than 20 minutes the tire pressure sensor light comes on, checked the pressure numerous times and its fine - weird part is if i leave my truck overnight when i drive in the monring its off again and doesnt come on until im stopped in rush hour traffic on my way home from work. have no idea what it would be

What's your pressure cold? 30? If it's higher than 30 cold it cold be over pressured. Also I could be a sensor not reporting get them reset at any tire shop or you local dealer

 

yea they are all at 30 - 29 on the digital reader, does getting them reset cost anything?

 

I have a 2010 and the recommended pressure is 35. If your at 29 you are too low. It will throw the light when its 4-5 lbs unde pressure. Check your door tag for recommende pressure.

Make sure the pressure is set to spec set it to 35. I get complaints and I just walk out with the TPMS tool and reset them and the customer isn't charged.

 

this may be a stupid question, but you did put the pressure monitors in your 20 inch wheels?

 

not stupid at all.. thats exactly what i was wondering too..
