Wheel bearing vs run flat tire noise

Hi everyone, I have a manual All4 S with about 62,000 miles on it.

I've been slowly going nuts over road noise in the car, and I'm not sure if it's because of run flat tires or not. I've never used run flats, and the car came with new Pirelli P7 A/S RFTs.

It's hard to describe the noise, but it's kinda like a hum? At low speeds, I can hear hum pause hum pause hum. As I accelerate, the pauses decrease in duration, until it reaches a point where it's just a loud constant "roar".

I've been researching RFT vs wheel bearings noise, and I'm not sure which it is. The noise doesn't change when I turn the steering wheel.

I was wondering if it was a wheel balance issue, but there's no shaking/vibration in the steering wheel either.

I want to ditch the RFTs, regardless if it's causing the noise or not, but they are new... Does anyone have some insight into this? Thanks!

Why a bearing over tire noise?

To check the bearing jack up the car put it into neutral hold the axle with one hand and rotate the wheel with the other. If the bearing is bad you’ll feel the vibration in the axle.

I'm going with wheel bearing too. Sounds a lot like the noise coming from my CMS that was diagnosed at the dealer as a wheel bearing.

According to some paperwork I have, one of both of the wheel bearings was replaced at 47,000 miles. I'm just at 60,000 miles now... Surely it can't go bad that fast?

I jacked up the car to test both the front left and right wheels, and didn't have any play in the wheels...

I would go with the run flats. A bad wheel bearing makes a heckuva noise (like a roar) plus 15,000 miles is not enough for it to go bad. I replaced my run flats with normal radial tires (like most owners on here do) and will never go back. Just keep an air compressor and flat-fix kit in the back if your Mini doesn't have a spare.

Wheel bearings dont necessarily make a 'heckuva noise' when they are beginning to fail and they generally fail over a period of time and get progressively noisier. What's not clear from Dragonzsoul's post is his comment "one of both of the wheel bearings was replaced". ?? Did you mean that one side was done or both sides were done at 47k and if so, front or back or ??? If a wheel bearing hasn't been replaced, then doing so at 60k is not unusual. Why not just take a mechanic out for a test drive and let a pro listen to and diagnose the problem?

And as for the run flats, I like my run-flats. My original Pirelli's lasted 7 summers and I've just replaced them with Bridgestone Drive-Guards and i like the Drive-Guards. I do run non-run flats (Nokian Hakkepellitta's) in the winter though.
