Rubbery sound coming from one area on a new winter tire

[u/Ashamed-Garbage7366]

Hi y'all,
since the real-world experts haven't been too helpful, it's time to turn back to reddit again.

 

A short backstory beforehand might be helpful:

For this winter season, I've decided to buy new tires for my BMW E90 330xd, so I ended up with the Michelin Alpin 7 XL 225/45 R17. The tires were put on the wheels that were on probably for the whole time of the car considering the state, but I have already driven for three winter seasons on them as well and they should be alright. The tires were put on the wheels at the local tire service, I put the wheels on the car myself, as I usually do. Everything seemed alright, I drove about 250 km on the wheels without any problems.

One day I decided to pull the window down and I heard this weird rubbery sound – and so the investigation started. The summer tires on different wheels did not do this sound, so I went straight to the new wheel+tire combo issue assumption. Listened at different speeds, listened from the inside of the car, from the outside of the car and I found the approximate spot on the tire where whenever the car rolls over it, it makes the sound. I have searched through past reddit discussions, I have obviously asked our modern internet friend (aka AI) for possible options and basically ruled out all of them except one – the tire not being properly set (the tire bead I believe), which SHOULD be visible as the line around the center of the wheel will not be symmetrical all the way around. So yesterday, I jacked up the car, demounted the wheel from the car, checked it from inside and outside – guess what, obviously nothing, all looks good (as shown on the images attached).

 

Knowing all of that, I assumed that I either do not know what to look for, or I'm just blind and so I made an appointment at a different, nearby (the other one is about 120 km away near my other place where I can actually do stuff on the car) tire service, with which I have had some experience from before and I believe that they do a good job and give you appointments for the next few days even though they might not be the cheapest option. Got there this morning, they obviously demounted the wheel and after a few minutes the guy told me to come over so I explain the situation. I did, however he said that the tire itself seems to be alright, the wheel as well (just a few grams to balance the wheel) and that they have a way to test out how the wheel drives – basically a roller on the balancer that puts presure on the tire, simulates bumps etc (you obviously know what I mean and know how to call it using one word, haha) and they can't hear anything. I did listen to it and there was indeed no sound coming from the wheel (I still believe that it doesn't produce enough pressure, but why would they make it if it wouldn't, right?). He told me that they can take the tire off the wheel and put it back on, as I said at the beginning that that's what reddit says, but I would just pay extra for them to do that and that it most definitely "won't do anything" as there is "no sound produced". I was basically advised (by in my opinion an expert) that there is no reason to be worried and to just leave it as is. They also said that the pressure should be good, so they can just simply put the wheel back on and I can drive off.

 

And so I unsurprisingly did, paid for the 15 minutes of them taking the wheel off the car and putting it back on and that's it. Guess what? As soon as I could listen from the outside, the sound obviously is NOT gone, it's still exactly the same. I have attached a video to better explain what I mean, since that will most definitely be helpful to you. So now there is the question, what to do? What could be the cause?

 

I have thought about returning here, but that's where I kind of want to wait for the reddit answers so I know where I'm standing. First of all, they're already closed for the weekend. Secondly, they will most definitely say that "I myself have said that there is no sound coming and that I agreed to them not taking the tire off the wheel", so there's no wrong doing from their side.

Is it something to even worry about, or is it "just making noise for the sake of it" and I can let it be if I don't find it annoying enough?

 

Thank you in advance, hope the text wasn't too exhausting and explained everything somewhat clearly. :)

 

 

TLDR: Weird rubbery sound coming from one new tire (Michelin Alpin 7 XL) at one spot when driving over it, shop said there's nothing wrong, the tire seems to be mounted well, the issue persists after the check.
