Vibration/Rumble at higher speeds

[Deleted member 10041]

Seen it mentioned a couple of times now, how many members cars are experiencing the vibration/rumble at higher speeds. Also what are the dealerships saying about it?

And is it happening across the range?

I suspect it's the tyres either out of balance or the steering geomitry is wrong

Also, at what speed are people getting this rumble?

Edit: this was the other thread on this topic.

Rumbling and vibration

Driving car home from dealer yesterday, I noticed noise and vibration at various speeds. The vibration can be felt all through the car, including the wheel, but there’s no visible steering wheel shake. I would err towards wheel balance, but the rumbling that goes with the vibration isn’t...

Not had it on our MG4 but on our previous Kia EV6 it was really bad for the first 1000 miles then it went away

General concensus was flat spots on tyres from sitting on the boat for 8 weeks those that suffered it all said it went away

So may be the same as that

That would explain it.

Temporary vs. semi-permanent flat-spotting​

In the majority of cases, flat-spotting is temporary. If a vehicle has been stationary for a few days or weeks – for example, if you’ve been away on vacation and parked the car at the airport – drivers may experience some slight vibrations during the first few miles of their journey. The flat spots will disappear once the tires have reached their operational temperature and regained their normal shape.

Semi-permanent flat-spotting will occur if the tires have been standing still under vehicle load for a month or longer. A typical situation where this can happen is if you’re storing your vehicle away for the winter months, or if it’s being transported overseas. The long standing times, especially in tandem with high temperatures and low tire pressure, can result in more severe flat-spotting that normal driving won’t remedy.

If you suspect that your tires have semi-permanent flat-spotting, you should contact your local tire specialist or garage in the first instance, and they’ll guide you through the options on how to fix it.
