Just notice my wifes M roadster has a very small leak on the right rear tire. There is a very small diameter nail in the tread about an inch from the sidewall. Its too small to remove and plug. I think that may make it worse. Fix a flat sealant? Need ideas, quick. Replacing one used tire for a new one seems stupid. Besides, no one around here will have one in stock. Everything has to be ordered. Need help quick, tis the season for my wife to be a b@#t%h. I pray for Jan. 2nd. She doesnt like driving my 4.8is, and she tells me she isnt high maintenance. Good God, help me.
