Over the last 2 days I have been having tire pressure issues, all 4 tires have been losing pressure. I have been using a good analog pressure gauge to check the tires. Three tires are down by 3 lbs. and the drivers rear tire is down by 6 lbs. My Roadster has 6914 miles and have the Conti ASP Tires, has anyone else experience this problem? I am going to mark the pressure to night when it cools down a little and check it again in the morning. I would assume that if the tires loose anymore pressure, then there are problems with the tires/rims. My car has not hit any large potholes most of the roads that I travel on are smooth country roads. I have also considered the temperature here, over the last 2 weeks the avg. temp here has been about 94 degrees. I am planning to take it to the dealer in the morning. Just had my 7000 mile service done about a week ago and the tire pressure was dead on. If anyone has any thoughts, please chime in.
