Wheel vibrating at high speed

Hi guys. I bought a 15 SQ4 a month or so ago with 30k miles.

A week after I put brand new rotors and pads and a set of Michelin pilot sport 3s. The place that did the work also did balancing ( regular, not road force )

After that I started feeling wheel vibration after I hit 75 and above ( I didnít go that fast the first week prior to putting new tires on )

I went to Maserati and got an alignment done, still same.

I went to two different dealers to ask to do road force balancing and after they each charged me 150 for diagnostic they said this car rides rough and nothing is wrong.

This is my first Maserati but for the life of me I believe that a performance car should feel anything at 80-90mph. I can do same on my wifeís Ford Explorer and not feel a thing. Now granted it has electronic steering and Ghibli does not.

I really love this car and not sure what to do. I thought it may be the tires but itís not like I bought some cheap eBay set.

Should I still take my chances and make them do a proper road force balance to eliminate that from the list?

I wanted to go and test ride another used Ghibli but canít find one close by

I just bought a 2015 SQ4 two weeks ago and noticed that it does tend to vibrate but not so much that I'm worried. I had a BMW 650i that was as smooth as glass when getting at high speeds. Not sure if it's the nature of the beast (maserati) or not?

I'll be curious what others say.

I have a 2014 SQ4 with 20" Urano's ... no vibration and very smooth at high speeds with Pirelli's PZero's, (well above what's mentioned above). I'm pretty sensitive to changes since I've owned the car since new and it still feels tight and smooth for riding on Pirelli's.

On a good highway, I'd say this car is as smooth as my wife's 5 series with run flats. On a rougher pavement with the my sport suspension you can definitely feel the road imperfections and the BMW rides much smoother.

it should be very smooth.
pirelli tires, in my experience, flat spot a good bit.
i'd venture to say the road force is high, as that is usually what contribute most to vibrations.
you should be able to get a printout of the roadforces as measured. the fix would be to spin the tire on the wheel to hopefully balance out with a better spot on the wheel.

an alternative solution to attempt, if you have the capability to lift all 4 tires off the ground...
deflate to 15psi, drive some miles to heat them up (carefully as the car can be squishy and unpredictable depending on surface, definitely won't handle like normal) try to stop as little as possible, lift it up off the ground on return, inflate the tires to about 50psi or max sidewall pressure and let it sit over night to cool. reset pressures to normal 32psi and hope it improved.
this is the only way i know of that MAY alleviate any flat spots.
this won't address any hard spots from manufacture.

good to hear bud, sometimes batches of tires need extra attention mounting to the best spot on the wheel.
low profile tires get finnicky nowadays.
