Sounds like a flat tyre. But what is it?

[waitetom]

Hello.

I drive a Mercedes CLK 270 cdi. It's a 2004 model.

The problem I have is that one of the rear wheels is making a sound as though the tyre is flat. It's making so much noise that I've had several people tell me that my tyre is flat.

The tyre is NOT flat, what could this noise be? Is it something to do with the tyre or something else altogether?

I would really appreciate any advice, thanks!

broken spring?

Poor quality tyre?

Wheel bearing?

What sort of noise? Like a hum?
As stated above, could be either a wheel bearing or poor quality tyre.
If your tyres have a thin wall, it could be that?

I had a rear tyre that was making a drumming noise (bom-bom-bom) that varied with road speed. I checked the outer tyre wall and made sure it had the correct pressure several times ... then I looked underneath the car and there was a bulge on the inner side wall.

I blame traffic calming - locally our speed humps are of a trapezoidal cross section and lots of local cars suffer from damage to the inner sidewall of the tyre, or even from chunks take out of the inner wheel rim.

If it is a humming or constant roaring noise, do you have a budget tyre or tyres fitted?

My wife's car needed two new tyres after a blowout and the other two had little tread remaining, so she bought a set of four budget tyres from the nearest tyre specialist to where she was at the time, getting a very good discount from am already low price. The noise from these cheap tyres was incredible, but they wore out very quickly so we didn't have to suffer it for too long.

Now she knows to buy Continental EcoContact or Michelin Energy tyres for long life, much lower noise and better fuel consumption - at least 4 mpg better according to the car's trip computer.

Wheel bearings given up the ghost, gives a grumbling sound akin to a flat tyre. Get it changed ASAP otherwise you might need a whole new hub

Swap the wheel with it's opposite number and see of the noise moves - I also had a rogue tyre (an Eagle F1) which went whoop whoop at around 30mph.

Can you rotate the wheel with the tyre off the ground.
If the noise is still there, it's probably the wheel bearing.
If the noise goes away - Check the inner wall of the tyre ... Less easy to see.
As said above ... Swap the wheel.
That will confirm or eliminate the tyre as a possible cause

Do you mean 'Dont panic Captain Manering"

The tyre could have a flatspot, this makes a drumming noise when travelling.

Take the wheel off and inspect it. You are not going to learn anything about it otherwise. Whilst there, check the bearings.

A type can "throw a tread", I've had one break a belt and "go square", another with a fairly large steel bolt stuck in it. Once a type has developed a flat spot, it is not going to recover.

Steady on ;-) t'was only posted yesterday, not everyone spends 24/7 on the computer.

I thought I had a bad wheel bearing. Olly had a look and found it was the tyres.
