Tyre wear.

[Nat]

Im at 11,500 miles and my front nearside tyre is done on the outside edge. The second layer of rubber is beginning to show through. Thus this tyre is toast.  Thing is the rest of the tyre is only half worn if that. The offside front tyre is still at half life all over if you like. This is most odd. Went and got 2 new fronts and had the suspension geometry checked on a hunter computer. It was all " all greens " when we went on it and we tweaked it a little just in case  but I have to say I don't think its not the suspension geometry.( not an obvious issue anyway)  Although within tolerance the left and right front camber are at maximum adjustment and they have told me that if I want more adjustment I would need to get a new upper control arm with an over or underdimension version. Currently camber on left is -0Deg31' and the right is 0deg07' so absolutely nothing in it.
No I don't live in Milton Keynes and drive round 3 million round abouts each year.
Anyone else had/have this problem , I can't be buying a new tyre every 10,000 miles surely.



Im a 40d 2013 SE with M sport suspension delete.

Any ideas/thoughts please let me know.
Regards,
Nat.

My X6 is going through tyres at about that rate too.  The only reason I have yet to change a set is that I alternate between winter and summer sets.  The Summer set have just 4mm left after probably 9,000 of the 15,000 on the car.

I'm not sure if it's the RFT type that is the issue, or the Dunlop tyres are short lifed but whatever it is, the tyre wear seems high and my tracking is correct too.

When I change them some time in 2014 I will look at a different brand to see if they are better.  The Michelins on my E53 lasted around 24k a set.

camber on the road so more weight running on the nearside?

Our front nearside outer edge is also wearing badly, we have a tyre section at work so I may get them to swap the fronts so the wear would then be on offside inner edge.

Typically this fast wearing off of the (RFT) tyres on the outsides, often coupled with sawtooth noise issues, may be the result of a too low tyre pressure.

Suggest you try 38 psi for front tyres and 35 psi for rear tyres. In addition, you may want to exchange the front wheels every 3k-4k miles (assuming you have non-directional tyres like the Bridgestones), the minor cost & effort are worth it.

I have been doing so with my new Bridgestones (275/315) on my X5 40d, which had a sawtooth issue when I bought it, and have had no uneven wear or sawtooth issues since.

The higher tyre pressure advice I got from a German X5 forum, and it works!

Hi,

I will try the higher tyre pressures. Unfortunately the Dunlop's are directional so cant rotate them round.
Rears are wearing evenly all the way accross with a little more wear on the centres of the tyres, but thats as expected as they are very wide. I do think the Dunlops are soft rubber, but still very disapointed with the wear rate. My other car is an M5 and I manage 15.000 miles out of a set of rears so this is very disapointing.
I don't like having odd tyres on the car, so perhaps when the rears wear out I will change all 4 for a different make of tyre see if that makes a difference. Clearly non directional seems to be a solution, its a case of finding a tyre depot that will co-operate on this. You would not believe how many now dont want to fit anything other than what they supply  and those that will help you out charge around £40 a corner. I have yet to find a centre that will fit a used tyre.
I guess I will have to do some research on non directional runflats. If anyone has any experience or suggestions let me know. I have kept this tyre and I will take it to show BMW when the car next goes in to be serviced, although I'm not sure what they will say or what good it will do. Not that it makes it any cheaper for me , but a bit reasuring to know it seems to be normal / I'm not the only one.

Regards,
Nat.

As said put the pressures up, I am running higher all round and the Dunlop RFT seem to be lasting better than the Bridgestones (so far). I have had a motorbike for 30+ years and it is in my blood to check tyre pressures weekly and it can make them last much longer.

Looks as if Pirelli, Dunlop and Bridgestone may be the only RFT suppliers.  The last time I had a car with Pirelli tyres (Leon Cupra R) it ate them in 9,000 miles which doesn't leave much choice.

If I was going non-RFT then I might just put Diamaris on.

Ive got exactly the same problem.
Outer edge front tyre wear. [Bridgestone RFT,s on 20" rims]..
Its just this week been into BMW to have a full KDS alighnment.
I requested a printout of the before and after settings to check what adjustment had been made, and it wasnt much...
I also had inner edge wear on the passenger side rear.
Hopefully the car is now going to wear its tyres more evenly, i hope so...
It does feel better on the road....But the verdict on tyre wear is still "out"....

Also.

I placed 40kg of ballast in the boot to pre load the car, as ill be towing a car trailer soon, [so it would simulate extra weight, tool boxes, trailer etc], but the service manager told me he wouldnt do the car if that was left in the boot....I wasnt best pleased... >:( >:( So he did it witout the "ballast"......

its self leveling anyway so no need for extra weight

Hmmm, strange it's only one side and it's the outer edge so I wouldn't have thought camber being the issue (as it would have to be positive camber not negative to get outer tyre wear). Even on the rears of most cars that run any kind of negative camber you wouldn't get just the inner edge with half wear across the rest of the tyre.

Usually if the inner/outer edge of a tyre is scrubbed, it's normally down to toe.

Perhaps a slight bush issue on one of the control arms or something causing it?

Not on the X6 it isn't.... .  That's an extra option unless you have the uprated tow capacity.  No airbags on the X6 normally.

its on an x5 tho isnt it?

[X5Sport]

But do they all now have it?  It was just a question......is it another if those 'trim' options?

When were looking at E70 X5's I was told they all have self levelling air suspension at the rear.
