I posted this on the SRT part of the forum and thought I may get more response here since it isn't necessarily an SRTonly topic. One other ? I have: what kind of wear pattern have other XF owners had? Front and rear. How many miles have you been able to get with tires? I realize that different brands, driving style, etc. will change what the wear on tires, but I would like to get a range to try to determine if my tire's wear is "normal" and what kind of tires other people like on their XF. Thanks!

Just replaced my Nangcangns tires (or whatever the name is-horrid tire) on the rear of my SRT w/Falken 452's. The china tires were put on by a pervious owner. The older tires showed scary amount of wear on the inside 3 inches. The tire on the right was worn down to the steel belt in places and the left was very worn in the same place. The unusual wear did not seem to be uniform around the tire. This seems to indicate a camber problem. It is my understanding that the rear camber is not adjustable on a XF. Other threads here have discussed the need to put an adjustable camber arm on any car that has been lowered because otherwise there will be very excessive tire wear on the inside of the tire. Exactly where my tires have worn badly. Since I just put on $500 worth of tires I would like them to last. My ?'s are: Is there any way I can find out if my car has been lowered? Is this a camber problem or something else? The tire place also indicated that the right front upper ball joint was worn and needed replacing. I looked at the part diagram and couldn't find an upper ball joint. Lower yes, upper no. Is this guy incompetent or b.s.'ing me? He also said I need a left front wheel bearing. He wanted to fix the rear camber problem but said he couldn't until the front problems were fixed. True? I know I made some assumptions here, but I'm willing to be corrected. Any advice some of you could give would be greatly appreciated. Thanks! p.s. I have just bought new Koni's for the car, so do you think putting these new shocks on will help/solve the problem?
