I am looking at a 2004 CTS-V and happened upon a site for this vehicle. The topic at hand was the tires on this car. Apparently all they come with are Goodyear run flats. All the people on this forum did was complain about these run flats. The vast majority said the most they got out of these tires were 10,000 miles before they had to be replaced. One guy said he went through 3 sets of tires in 30,000 miles. And Cadillac wasn't doing jack to help the customers. Many said they will never buy another caddilac because of this.
I was looking at a new 3, as I have had 3 bmw's till now. But I read so much bad stuff about these tires (BMW only puts on run flats - the is no option for regular high perfomance rubber) and having to replace them by about 10,000 miles, I decided not to get one this go around. Again numerous owners said they were done with BMW's until these tires go away or they had the option for a conventional tire.
The point is, there seems to be a common thread here. If you dont' mind buying a new set of tires every 10,000, then these cars may not be for you.
Any comments would be appreciated.
