Sorry for the noob post, but I need some help with choosing rims + winter tires for me F10, as I'm kind of sick of either being without a car or being part of the 'hey can I drive a RWD with summer tyres on snow' Belgian lunacy here... I have a few questions.

Re tires - I'm pretty much torn between Dunlop 3D RFTs and Pirelli 210 Sottozero S2 RFT. They look more or less on par but any feedback? I also considered the Dunlop 4Ds but they don't come in 17" RFT sizes and I'd hate lugging around a spare, so...

For wheels I'm even more clueless. I'll pick up a set of 17x8.0 5x120 ET35 72.6, but:

1. Is ET35 going to be OK? Yes, according to what I read...?
2. Any recommendations on brands? I don't need anything fancy, but still should be good quality.
3. I have the M sport package which means I currently have 245/45 in the front and 275/40 in the rear (18") + VDC suspension - does this make any difference?
4. Finally, are there any compatibility issues in particular between the tires I've listed and the wheels I need to look out for?

Thanks in advance
