i have a 2007 fx4 f-150 with 6in lift and 35in mickey thompson tires.the low tire light comes on and every now and then it will start to blink.not sure if there is somthing wrong or its just cause i have the bigger tires.i dont have a programmer.....yet that is. so if i clear the code will it come back?

 

Second post today on low tire pressure sensors. Have you checked the tire pressure with an accurate air pressure guage? Is this right after a tire/rim replacement?

 

If the light is flashing you may have a sensor going bad...or came loose inside the tire.
