I use a place called Schlott Tire in Tewksbury, MA. About 15 miles North of Boston. They fixed one of my tires that had a rock in it and they dismounted 2 tires and put drag radials on. I did end up with some slight scratches on the rim when they mouted the drag radials. They said they were really tough to get the 275's on the 8 1/2" rim.
Also if you search the threads, I know thebigjimsho found someplace local to swap his tires.
