im sorry maybe i dont know about the e92s but how damn expensive can it be to rotate your tires, christ you can do it your self with your own tools, all you do it move the tires around

 

First, BMW is very explicit about not rotating tires. That only serves to transfer problems around.

Second, don't you think it would make sense to ask a BMW dealer, as opposed to a dealer of another brand?

 

Tires

Not sure about the run flats, but feathering on the edges is usually a result of low tire inflation or alignment issues. If you run the pressures on the doors this tends to wear out the outer edges of the tires first. I usually run 35 or 36 psi to get even wear from center to edge.

 

That dealer is full of crap. What you're describing is either a function of the tire design, alignment (like bad camber), or not enough inflation pressure.

 

Too many cars, not enough car places.

Rotating tires is not expensive, money wise. Just it takes a long time. Very crowded here and you wait for hours for most jobs. If I had the tools and space, I would do the job myself, definitely.

 

Thank you.

-- Good to know this. Thanks.

-- I will. When I wrote this post, it was late and did not have access to the dealer.

 

Feathering, incorrectly described.

What I meant to say is the outer edges of the tires are not smooth. I looked up feathering and no, this is not what I have. I increased the tire pressure to see what happens.

Tire Rotation Examined
Text and Photo By Mike Miller

Initially, if your BMW has staggered tire and wheel sizing, meaning the rear tires are bigger than the front tires, click the little box in the upper right hand corner of your screen. You can't rotate your tires anyway.

BMW presently recommends against rotating tires. Here's why: In the US, it's normal to bend wheels occasionally, to one extent or another. And not all tires anywhere in the world are perfectly round. When a technician mounts and balances new tires, during the balancing process he will typically note which tire and wheel assembly is the "roundest", i.e., which has the least runout and requires the least weight to achieve 000 on the balancer. These two "roundest" assemblies he will mount at the front owing to BMW's incredible sensitivity to wheel balancing issues.

Then, down the road, the owner or another well-meaning tech rotates the tires front-to-rear. Next thing you know Old Jed's a millionaire -- you've got a vibration in the steering wheel. The reason is that one of the tire and wheel assemblies formerly at the rear and now at the front are not entirely round. If a technician rotated the tires, the customer then brings the car back to the shop complaining of a vibration, requiring a road test, dismounting, balancing, more road testing, etc. Often the customer will balk at paying for the additional work.

Moreover, at BMW dealerships, the customer satisfaction index (CSI) is hugely important in dealer relations with BMW of North America. When NA does a random CSI call on a service customer, scenarios like the foregoing result in comments like, "Well, I had my car at Big Mega Dealer and now I have a front-end vibration! So, I guess I can't give them a high score now can I?" The system is not set up for further explanation, and without that further explanation, the customer input impacts negatively on the dealer's CSI score. Eventually dealers complained to BMW of North America, and the end result is the no-rotation policy.

The thinking is, when you have a BMW that doesn't shake, leave it alone.

Now, armed with this knowledge, if you want to rotate your tires front-to-rear, there's no doubt that you'll get longer tire life. Just be aware of the possible balancing ramifications.

The presumption that the customer is incapable of understanding, or unwilling to understand, these issues is, unfortunately, often correct. However, Roundel Tech Talk takes the approach that it is better to at least attempt to educate people rather than throw out the baby with the bath water.

Nice article...Steve. :thumbup:

I wish I had had that to show my local shop when they looked at me cross-eyed,
right after I told them BMW's position on this matter.

 

I just put 4 new Bridgestones on my 745i for teh same reason. The outer edge was worn and it was explained to me that the vehicle woudl simply act that way no tire rotations would fix the way they wore but woudl probably cause vibration issues. Bought 4 tires and put the old ones on ebay.

I always found it odd to pay for a disposal fee when the tires are resold as used or recycled , I suspect at a profit to the dealer.

Thanks Rich---even though we have "talked" on other posts (not always agreeing )
i try to find the best info that I can and I am always willing to be corrected.

 

Its cool....this is only an Internet forum after all.

BTW, I'm really happy for everyone that wanted the 335 Sedan to be a reality, even though deep down I wished it would have occurred a little later.
It now seems to be definitive for the Fall......

I'm still inclined to believe that it won't be cheap.

 

ditto, to both--same for the E92 coupe-the poor mans 6 series coupe (BMW speak for mo money, mo money, mo money!)

You should set the pressure to what the decal says. Are you sure you haven't hit any potholes and knocked the alignment out of whack?
