Of late I’ve noticed and increase in a distinct whirring noise coming from the front wheels, particularly on smooth Tarmac.
I took my car to the dealers and they filmed the tyres on their magic machine and said they are severely “out of shape” i.e. not very round and this could be caused by potholes etc.
I then went to KwikFit to see what they’d say without prompting and they just noticed uneven wear across the tyre which is apparently common on my make of car.
I then had a look at them myself and noticed a weird squiggly wear to the edges of the centre groove. In my mind this would explain the whirring noise.
So.. What causes the below and are they fuberered!?
What tyre make/model? Just out of interest.. I was warned off replacing mine with Dunlop Sport Fastresponse for exactly this reason (I have one worn fitted that that ovalized).. guess which tyre the local fitter suggested 1st.
I had a pair of Hankooks taken off recently that made the car sound as if the wheel bearings had gone. The casing was visibly closer to fifty pence piece shape than circular – the fitter has seen a few like that. Mine were only half worn.
Laser hunter alignment would reveal your right/wrong suspension geometry. Many modern cars suspension set up hide sawtooth problems. Recently I checked my car fronts and rears were out of shape and required alignment. Changed tyres after alignment too and noise is gone. Very well pleased with results and have print out too. Costed me full £120 to sort out though.
It didn’t occur to me to look at a picture of the tread of a new one!
There’s no vibration at the steering or anything but the whirring is getting worse. I think I will have to change them as BMW marked them as red on the car diagnostics ‘puter thing (everything else green) but at £135 each I was hoping I could make them last a bit longer as they’re only half worn :-/

What reason did they give for them needing to be changed ?
If they are only half worn, I would be asking what the issue was.
Nealglover – they said the tyres are severely out of shape, distorted and basically not very round. Tbh I have a good relationship with them and took the car in thinking the whirring was a wheel bearing.
If they were looking to make a few quid they could have just said the bearings need replacing I guess.
The tyres are indeed the correct size and load rating.
We had Toyos gone out of shape on the wifes mini recently and rumbled badly like a wheelbearing. I guess the state of the roads and humps punish tyres these days more than ever.
I’ve hit some massive and unavoidable potholes at about 50mph and can see it it could be a possibility that they’ve been damaged by them. Also, they’re runflats so perhaps likely to take bigger hits without popping due to the reinforcements perhaps??
Apparently this none round tyres are getting more common. The c max made that noise, you will probably find that a new set will cure it for a while but if your car is out of line it will develop again. I’d recommend the 4 wheel alignment before spending a lot of money on new tyres.
They’re still legal though, 1.6mm through the centre 3/4 of the width around the full circumference with no cuts or bulges on the side walls the law states.
