Discount Tire lost my business when they siezed up 2 lug nuts to inform the they don't fix them because they aint mechanics. I told the manager with me making hospital runs with my wife at stupid hours of the night & needing to drive 1 -1.5 hours if there was a problem they would have one of biblical size.Truth. Not long after I inherited my dad's Durango, I ran over a large screw in the parking lot at work on a weekend. Could not BUDGE the lug nuts - I even stood on the lug wrench, and I weigh 300lb. Had to call roadside assistance, and that dude had to use a breakbar with a four foot pipe over the handle plus all his weight to get enough leverage. Discount Tire somewhere in far south Austin did that one.
