Where I live the roads are very rough and cars with aluminium alloy trailing arms dont tend to cope very well, owners of newer audi models for expample complain about having to replace these quite often. It was only after I bought my e60 I found out that it too had aluminium suspension and I wonder with the added burden of sports suspension and runflats whether I would have to deal with the same issue. Any one with any such experience?

its the element that attaches the wheel to the chassis of the car. Looks something like this

p.s. aluminium ones tend to warp from road holes

In this case, you should not go for lower profile tyres.

Keep the original 225/50 17" tires on!

This way the tyre will work as a part of the suspension.

Even the BMW owners manual says that the 245/40 18" (or even lower profile) could harm the car.

I've got the M-pack so tyres are 245/40 18" rfts but as soon as I have destroyed them would change to non-rfts. For my winter set I've gone with 225/50 17" with Dunlop M3 non-rfts on replica wheels. Cant wait to slot them on the current setup breaks my back on shitty roads.

I know what you mean. Where are you from?

The weather overhere will be icy next week, so I will throw my 225/55 16"s under next week.

The car will be about 6 dB's quieter and no more tramlining will occure.

But the looks will go

Hello neighbour!
The first time i see the temperature drop below 2 degrees or frozing temp or some snow , i'll garage my car... and brake-up with it till spring. A passat 4 motion is better suited for this.

Hey so i should look after cracks, or bents? We do have ALOT of bad roads....the thing is 90% of the time i use the center city roads wich are good but sometimes i take longer trips and i get carried away and find myself taking potholes and bumps and so on....feels like the car is tearing apart :'( :'( :'(

I know exactly what you mean, I wouldnt go for larger rims if I were you. I know the 18s look small for the car especially at the rear but where we live roads are a big issue
