20" Run Flate Tire Rotation? and How?
 

Do you suppose to rotate the run flat tires for Style 214 20" wheels?
Given the rear and the front wheels are different width I dont think you can roated them right?

I don't think you can. Even with 18" tires on my E53, my SA said BMW does not recommend rotating the tires. I guess they were right. 50K miles later, my tires are still pretty even and show no signs of uneven wear.

Since the fronts and rears are different sizes and the tires are unidirectional, the only way to rotate them is to have them dismounted from the wheels and remount them on the opposite sides (rotating in the same direction). Considering the cost of these tires, it is a worth while expense IMO that most quality tire shops can do.

crazy about bmw but yep no rotating.
taking the tire off the rim to rotate would cause more wear on the tire then not rotating them.

what about the 19's (same size all around)?

??:confused:

Standard front to rear on same side rotation.

I have an E90 with 17" tyres, all the same size.

I decided to swap the front with the rear as the rear were wearing out faster - but I was sorry that I did.

After I swapped the tyres (a few thousand KM later) I had to change all 4 tyres as they were wearing really strange. It seemed that the font and rear wear on the inside and outside differently. I ended up with what looked like a ridge in the middle of the tyre (and it didn't look good).

When I was changing the tyres the BMW service guy wanted to start adjusting the rear tracking (I think he said tracking) because the tyres looked strange - then I told him what I had done and he said that was the cause.

I reckon I would have got more mileage out of my front tyres if I didn't do the swap

The reason this happen was you waited too long before rotating. You should rotate every 5K miles or 8K km.

Does anyone know what there camber settings are for 20 or 21" wheels on the E70?
