text: should i continue to drive with a screw embedded in my car tire? i found a 5mm diameter bolt or screw sticking out of my tire (goodyear all terrain on a 4wd). should i  pull it out? what is the risk or a tire blow out? if you can find a discount tire store near you, i'd advise going there. they pull out and repair tires with nails and whatnot in them for free, no need to do the dirty work yourself.  they also clean the tire :p
