I have a 2012 Ultimate with Continental tires. The car was purchased late April 2012, and I currently have just under 25,000 miles on the clock, or about 1,400 miles per month.
Today, I replaced a second rear tire. The first succumbed to an unrepairable sidewall puncture. The second had an unspecified defect. In recent week, it was losing a couple of lbs. of air pressure a week, until the rate jumped to 1 lb. of air pressure per hour last night and this morning.
It seems that the dashboard warning light does not come on until air pressure drops to about 22 lbs. That is slightly more than 25% of the recommended pressure of 30 lbs. Because of the relatively low profile of these Continental tires, and because the tire in question is the rear right which is out of view when I enter the driver's seat, a pressure problem can be difficult to spot until well advanced. Yes, I know that tire pressure should be tested periodically, and probably more frequently than I have been doing. Nevertheless, the dashboard warning doesn't alert until it is almost too late and it is otherwise difficult to notice when a tire is slack.
Added to this tale of woe, my car has been pulling to one side. I had the alignment checked. The right front tire has apparently had its belts warped and needs to be replaced. This area has had a lot of construction work on the local interstate highways, and my tires have been taking a pounding.
Question. Now that Equus models have been on the road in fairly good numbers, and miles are piling up on the clock, have Continental tires, in general, proved to be a good choice for you, or are they becoming problematic? In the past, on my Lexus LS 430, I was pleased with the performance of Michelin (the Dunlops that came on the car wore out very quickly). I don't want to perpetuate a problem and keep replacing tires of the same brand and type one at a time. If the Continentals are just not robust enough, I would rather replace them all with a better tire at one time and be done.
Any thoughts that you may wish to share would be appreciated.
