Vibrations while driving

Got a 2020 Genesis G70. The car is great but i get vibrations when im driving 135km+ . Did a road force balance and everything and also have new winter tires on em.
Just curios, what do you think the issue is.

This is my set up

They are aftermarket wheels.
GTS PERFORMANCE WHEEL, G709
18x8.5 5/114.3 +35 73.1 Matte Black. I have a square set up.
Plastic hub ring 67.1mm-73.1mm

Tires:
Front Axle: Michelin Xi3 225/45R18
Rear Axle: Continental VikingContact 7 225/45R18

Although this isn't in the right subforum, I've had headaches trying to diagnose vibrations on certain sets of aftermarket wheels and have had mechanics at a loss for suggestions (proper hub sizes and balance).

Maybe stay below 135 km/h.

It's quite clear what your solution is. Part out.

Hello,

It did that to me twice this winter, also just at "high speed", check all you rims if you don't have some ice stuck on the inside edge, it completely unbalanced my wheels and made the vibrations when driving fast. Once removed everything went fine again.

How bad is the vibration? I have a Stinger and I don't have that issue with my square setup at your speed.

You have different winter tires for front and back wheels?!

I think you are on the right track. But rather "balance" of the tires I would suggest.

Also, perhaps the interface between the chair and the steering wheel - joke.

Why do you have different tires on the front vs back? That could be the reason.
Could be an issue with the wheels, slightly bent or something.
Could be a bad tire or belt inside is off.

Wait until the summer and put on the summer tires and see if it goes away, if it does then at least you know for sure its a tire/wheel issue vs suspension issue.

There is your problem. Put everything back to stock and troubleshoot from there.

It could be due to tire. Correct me if I am wrong, the tires are "Low profile Tire". The suspension design system could be an issue.

Other area to look is Engine Mount, Suspension Axle, Inner CV Joint, and alignment.

Speed limit goes up to 110km/h, if the OP is in Ontario, on some roads, with the reported 20% over "police will ignore you".

Like someone else said most likely ice frozen on some part of the wheels. Happened to me last year and just took it through a car wash with undersray and it stopped the vibrations.
If that isnt the case, either bent rim or bad tires. If tires see if they are directional and mounted backwards.
