There have been several recent posts on this topic and some older ones also where people are getting similar issues to what you have described, some with GG tyres. With my old Continental Cross Contact tyres, which were very quiet for a long time, I had the same thing after about a year (30,000km) and I was really scared my wheel bearings had seized or something similar. Put the OEM tyres on and no vibration at all. My D697's after about 30,000km are now just starting to exhibit the same sort of behaviour, although not as bad as the Contis. The silly thing is that there is also nothing visible on the tyres that would indicate that such a vibration could occur.

As I said, don't discount the tyres so readily.

Agreed. I thought it was a wheel bearing and replaced it and it made no difference. Put the old wheel bearing back and again it made no difference. Sniegy pointed out to me the feathering on the LHF tyre - run you hand over the tyre against the direction of rotation and you can feel the ridges. There's nothing particularly wrong, just irritating.

I would not believe it was tyres until I started to experiment, but I do think that's what it is.

Diana, it may just be your quiet modern car slowly evolving into a proper Land Rover!

In all seriousness though, I'm another vote for tyres, on Dad's Navara (don't tell anyone he drives a Navara!) he had the same issue, to the point he replaced front unit hubs, which didn't correct it, and then we discovered it was tyres, D3/4's seem to be very hard on tyres, in the case of Arthur's anyway, so it would surprise me if it was anything else.

Hi Will so are you changing your name to "Mr Datsun" or "Mr UD" :wasntme:

It just seems so very very weird that this new noise is sooooo different to any tyre noise I have ever had, and remember I have had them all. Including bar tread Oly Steeltrack and APL,XtraGrip,XZL,XMS,Duellers,BFG AT and MT,Synchrome and road patterns.

There is a little feathering, so I will rotate front to rear and see.

I got my tyres rebalanced & rotated at the last service & the noise is still there.
MLR investigated the service before and came to the same solution as me - harmonic vibration noise out of the tyres.

Cheers

Is there anyone at the club with whom you could swap wheels for even just a few kms of test driving to see if that made a difference?
Just a thought.

We keep coming back to the same issue, I have had noise from the ATs since I originally picked up the car from the dealer (45,000 km now). On different road surfaces it varies cometimes sounding like the diff is going.

This new noise is nothing like that.

I know it's frustrating, but the only way to 'know' it's not the tyres is to eliminate them as the cause. So if you could somehow swap over to a set of wheels/tyres which are known to be quiet and from a similar vehicle, and after a suitable drive, your noise continues then you know it's not your tyres and we on this forum can eat humble pie. It will mean, though, you still have a noise of unknown origin :(
Mind you, the noises the rest of us are getting could turn out to not be the tyres after all :o
Not a fourth Amigo?!:twisted:

I am going to rotate them first and see but I'm not confident, in the slightest.

Hi Diana,

We met at the LROC xmas party, I have the Stornoway Grey D4, I asked whether you had this noise back then which you didn't (hope I didn't curse you by asking). I've tried the tyre rotation and balance twice since the noise first appeared but no change.
Regardless of which tyre is where mine always seems to come from the drivers front wheel, I've checked for wheel bearing play but it seems fine there is no logical connection from the symptoms to the tyres but I'm starting to believe everyone else because there is nothing left.
My last test before I totally convert is try changing the tyres, I have a friend with a new D4 so I'll swap the 2 fronts with his and see if it goes away.

If it is the tyres my next concern will be how much damage will this cause other parts of the car like suspension and steering if we can't get rid of it?
