Smaller tyres?

Iím running 225/50/18 all around on my f34.

I found a set of wheels and tires 235/45/17 for an E46. Iíd like to use these as a winter setup as the tires are Bridgestone blizzaks.

I know itíll affect mpg and mph calculations but is there anything that would prevent me from doin it?

Make sure they clear your brakes (correct offset). Otherwise should be fine.

Wider tires don't work as well in snow. If anything you'd want narrower, say 215/55.

Thanks for the insight, I appreciate it.

Looked at specs for a 2006 e46 and the offset is the same @ ET34.

However, if I use 17 itís recommended I go 225/55/17

The difference in the aspect ratio worries me. Is the 10mm difference concerning?
