Definitely check if the rear shocks are leaking. I had the same experience but just assumed was normal part of the ride quality of an aggressive sport sedan in sport or track mode. Recent dealership oil change revealed rear shock leak and took pictures for me. Bit the bullet and had the rears changed out for brand new OEMs. I have a 2016 V that I picked up used a couple years ago. The ride is sooooo much better and can't believe I was driving around thinking the bumpy ride was normal. Now driving in sport or track mode with new rear shocks is like the drive feel in tour with the old shocks. Night and day difference for sure!

Run tires at 35 psi like the placard in the door says to do. Rides a lot worse at 37 in my experience.

There is definitely a noticeable difference between ~38psi and ~32psi with regards to ride comfort. I've never had a car that was so sensitive to tire pressure.

32 psi? Is that a flat tire?

32 psi? Is that a flat tire?

seriously, who heats their tires to pressurize them to the manufacturer's recommendation? wtf is wrong with people?

My ATS-V just got new tires last week. I followed Mfr. recommend psi at 35 on the previous set of tires. They cupped on the edges and were louder than, well, what they should be. So my new set is going to roll at 37 psi to avoid the edges wearing out prematurely. Of course I could drive like my wife.......

Thanks man, sounds like what I have, it's definitely in the rear, next time it's in the garage I'll ask for an inspection.

These tires are for sure sensitive to pressure. I had better times at the track at 35psi than 28psi.

I have a’09 cts v psi at 35 but the ride is rough

Has anyone else experienced the same.?

 

[tinman]

I keep mine at 36.

At the complimentary CTSV driving instruction class in Las Vegas the track cars were ~32psi cold, don't remember the hot but likely +4psi and they stuck the track pretty good. on the street a pothole may bend a wheel that low.

Look inside the driver's door for the factory sticker. It has the Cadillac recommended tire pressure for your tires. Start there
