What did your tuner say about that? I'm keen to get mine removed. It seems fairly safe mod provided that you don't cook your transmission fluid and keep it fresh.
FWIW, I got a set of V40 rims (7.5") with 225/45/R17 stock Pirellis on my C30. Definitely more grip off the line. Handling seems more or less the same, although the stock tyres aren't the best for performance, and I rarely push the car hard in the bends. No rubbing, not one bit. Biggest downside is that the rims seem more prone to kerbing than the stock 205 on 7".
If I can wear these out, I'd be keen to get a set of PS4S down the line.
