I had a screw imbedded in the drivers rear tire also. The dealer would NOT touch the repair as they were afraid of patching a "z" rated tire. That seemed alittle silly to me but they did give me the name os a Michlin dealer and he had no problems removing and placing a patch on the inside. He is also the one that did the research for me on real "snow treaded" tires for our winter driving. I'm still waiting for the first good snow to see how she performs on the white stuff.
