1999 Cadillac DeVille review from North America

Left rear door always failed to close easily. Must use a firm closing motion or it remains ajar.

I have a 1999 De Ville Sedan with 52,000 miles on the original set of tires. My inside driver's door did not have one of those tire pressure notifications glued to the side. I always thought 35 psi was the standard so that is what was set for the first 50,000-miles. I recently checked the Internet and found the recommended tire pressure. Also, the mechanic at the Cadillac dealer confirmed the specifications call for 30 psi front and back.

The vibration problem started AFTER I decreased the Michelin XW4 tire pressure from 35 psi to 30 psi and after about 2,000-miles of travel. I reduced the air pressure back up to 35 psi and the vibrations lessened. A couple days later I got a left-rear flat. The tire was worn in a cuffed area about 3 inches by 2 inches on the outside tread.

I took the tire to a tire store. The counter guy there said the belt had slipped and would compensate me $75.00. I was so elated that I told the guy to put 4 new tires on and toss the Michelins in the trash. I ended up getting a set of Kumho 795 Touring A/S P225/60R-16 97S BSW, Excellent All-Season Performance, Tread-wear: 560 Traction: A Temperature: B and meets or exceeds original equipment speed rating. These tires have a 75,000-mile warranty. I expected a "hard" ride. But to my surprise they ride soft and quiet.

But most importantly, the vibration is gone. I'm back to a smooth and straight drive.
