Great one of my tires has a nail in it and I can hear the air leaking. Went to Costco to ask for a plug, the guy said they were to busy and told me to come another day . Went to Firestone and they said no due to it being run flats and Continentals policy on plugs . Seeing its Sunday everyone else is closed. Gonna go to tire shop and replacing hopefully just 1 tire and not a pair of new crap flats...I mean run flats. My car is on 2 front jack stands right now you guys think that's okay?
