When I picked up a sheet metal screw in Del Mar, CA, I was directed to a Discount Tire shop. They follow the above. Excellent service, btw: out in half an hour, very courteous, reblacked all four outer sidewalls, didn't charge (said it was a "free fix a flat day" - ha!) and came with a nationwide guarantee. Tire is about to be changed out with an additional 14,000 miles or so on it, much at "out west" speeds, and it's doing fine.
