P 195 / 65 R 15 There seems to be an issue with the tires (4) staying inflated My safety was put at risk because vehicle wobbles when I get to a certain speed and I have to constantly put air in the tire daily The problem has been reported to carmax in Stockbridge GA The mechanic has inspected the tires I did not get any warnings about the tire pressure until after I put the spare on the vehicle then the low tire pressure sensor came on the date is unknown
