I had two 16d nails, like the ones stuck together for a nail gun, in the rear tire of my Harley. Both ends were sticking out from the corner of the sidewall. Entry near the bottom, exit from the sidewall. Had no idea how long they were there as the air loss was minimal.
Thanks Trimjb - turned off the lane assist and seems problems has gone away. Last truck drove was 1998 F-150 and now getting used truck driving all over. Need to get use to the knobby tires instead of the low profile performance tires for Fusion Sport AWD for the last 14 1/2 years. Thanks Again..
