New tires most likely will solve Your problem.
My wife's X5 with the Sport Activity Package had same symptoms and changing the tires made a huge difference.
You will feel a world of difference in ride quality with the new tires.
Thank You.

I have read this before, can't remember what thread and too lazy/possibly almost drunk to dig up the thread to find it, but another 4GS member had the same symptoms when they needed new tires. I know sometimes buying new tires isn't cheap or fun but in this case it sounds like your car could really use it.

Thanks fellas! I guess I will be investing in some tires. I will report back after the change. Thanks again.

If youre going for new tires and want to smooth out the ride a bit, I would consider upgrading the sizes to 245-40-19 in the front and a 275-35-19 in the rear..

This will give you a bit more sidewall, and let you run lower pressure to smooth out the ride a bit (larger volume = more air for more load capacity = less pressure required). Also more tire width should increase traction for better handling, braking, etc, and looks bad *** as a bonus!!

This is what I will be doing when my tires run out anyway.. and I would love to see a pic if you do this please!

Thats an interesting idea. Sounds really good in theory. Has anyone done this here on the forums that can share?

I wouldn't mess with the tire size. Quality rubber, fresh, will make a huge and immediate difference. I always love getting new tires because it's the single most noticeable change you can make (generally speaking) and can breathe new life and comfort into a used car.

I have read others switching to this tire size without issue on this site.

I have done this on my Jaguar personally in the past and it was a notable difference all around in both comfort and performance. And oh yeah, it looks sweet too!

Without a doubt I will do this when I need tires, and they will be Michelin Super Sports for handling, braking, smoothness, and durability.. the tires are indeed the most drastic improvement you can make to any vehicle. One size isnt a huge difference as say 3 sizes (which I have also done on a classic Chevy) of course, but it should yield slight improvements all around based on my past experience.

Be sure to let us know when you get new tires if your car is still rocking like a boat. It may just be something entirely different causing that feeling.

Sorry - I couldn't resist!

Soooo.. did you get them new tires yet, and did this eradicate the "boat effect"?!!! We need to know!

Also, if you got tires did you upgrade the sizing like another very informative member had suggested?

I replaced the Dunlops on my '13 GS F Sport with Michelin Pilot Super Sports. They made the ride and handling better for the first 3k miles, then the next 2k miles I started to feel like my car was bottoming out if I'd go over a road that dipped. I traded the car, so I never had it checked but it was constant. I was starting to wonder if a shock was leaking or something along those lines. I did hit a really deep pothole that bent a rim, which I had straightened, so that may have done some unseen damage. Often, I really thought I was going to scrape the front bumper on the road, even if it wasn't a huge dip. I had my tires set at 33psi all around. It just didn't feel like the suspension was as firm as it was in the beginning, and my GS had 20,500 miles on her when I sold her.

As I mentioned in the comparison to my new S5, my Lexus (even in normal mode) got pretty sensitive to pothole and dips in the road. The S5, even in Dynamic, bounces back from them like nothing.

Maybe there is something with the Michelins after all?
