It does not have Continentals. It has Bridgestone Turanza's. 245x50x18/s. It is the Performance Sedan not the regular DTS. I have the same air pressure etc. Dealer can't explain it either. The speed limiter is also set different. The first one was at 130 MPH. This one is at 123 MPH. I have the build sheets for both cars. They are identical in suspension etc.
