MG4 Rumbling and vibration

[Zeller]

Please help me, I don't know what the solution will be.
I bought 4 new tires- Kleber QUADRAXER 3 215/50 r17.
Shakes the steering wheel between 100-115km/h. The situation improved a bit when we replaced the front wheels and put them in reverse. e.g. at 113km/h the shaking stopped, but the main problem remained.
Barely noticeable, but just enough to get the blood out of your fingers. HUNTER machine checked the rubber, found no defects. No defects in the rims. Here I stand with very expensive 4 new tires and I can't use the car properly because it shakes steering wheel.
The seller can't do anything about the situation, because according to the machines the rubber is perfectly good.
He says my undercarriage is too sensitive.
I understand, but it was a lot of money for me and I don't know what to do now. If I have to buy new tires again, what should I buy from 4 seasons to make them good?
I'm getting annoyed with this car and its stupidity.

Thank you, if you can give me some meaningful help/advice.

Michel Cross-Climate 2s have been recommended by a lot of people. I have them and no problems.

Do you have the XPower version? It can be prone to vibrations and there's lots of threads in that forum covering it.

I only have SR. I don't have that kind of money

Sounds like the tyres may have been improperly fitted or balanced.

No answer to that!

Seriously though, can't help you, but someone will. Good luck.

Standard problem solving is to ask these questions. 1. did the issue exist before fitting these tyres? If not then highly likely the tyre is the cause. I would have another tyre business fit another 4 tyres, say some bridgestones or pirelli. See if it fixes the issue...

Then probably balanced wheels and good tyres should work fine. Have you changed from the standard sizes?

We are obviously beyond pure logic. The problem is that I say it shakes, and the shop says they have machine tested it and found no faults. I also can't "walk away from the purchase" because I bought it 2 months ago, but we've just been on the highway. It was not found out in town.

A vibration that comes on at speed and fades away again at a higher speed, is indicative of unbalanced wheels, most commonly a weight that has fallen off, which I would expect the Hunter machine to pick up on. I appreciate the business says their Hunter machine says all if fine but when has the machine last been calibrated? Don't waste your time arguing though, find another tyre shop and tell them about the vibration and see what they recommend.

Kleber QUADRAXER 3 tyres get good reviews online, apparently they are a sub brand owned by Michelin. It is always possible they weren't stored correctly, although you'd expect the Hunter machine to show an issue with the tyres then.

We once sold rims and tyres to a guy how felt a vibration through the wheel afterwards. He described it as shaking the fillings out of his teeth. I collected and delivered the car twice (he worked for one of our biggest customers, so a bit of extra service) and never felt any vibrations. Our Hunter machines (calibrated every morning I might add) couldn't see anything out of specification either. In the end we just put his old rims back on the car and that fixed it for him. I never felt the difference, although to be fair he may have been doing different speeds. But in your case you kept your original rims...

If it still happens when you swap the wheels front to back, something might have knocked the steering/suspension geometry out of alignment. Wouldn't take a half decent garage or tyre fitting establishment long to check that. Or even a dealer if you have deep pockets...
