I have recently changed from my SRi wheels (with 215/50/17's) to 18" VX wheels with 225/40/18 and to be honest I can't tell the difference, you won't have a problem at all mate.

Thats funny, because i did notice a difference. Having run on 17, 18 and 19, I would choose 17's every time now. The trade off in ride quality just isn't worth it IMO.

Slight correction, I have 225/45/18's.

I have had pretty much all sizes of wheels over the years in various cars and have never come across any "massive" differences, even going to 19's on my last 330d still wasn't much of a difference - maybe it just depends on peoples preferences, but I prefer a firmer ride anyway (oo-er)

I started off with 215/50/17 - the standard tyres on my standard 17s and then changed to 225/45/17. Noticed a slight difference in ride, and I mean slight. The drive was better though.

Then I got m8 18s with 225/40/18 and I was expecting the ride to be quite a bit firmer. I actually think it was no worse than when on the 225/45/17 i.e. it was a nice ride. The handling also improved on the 18s I felt, so I've never regretted it.
