i have a set of diamond cut wheels on my car at the moment with 205/40/17. i am looking at buying a set of soft spoke version and was wondering would i be able to fit on 215/45/17 without any issues of rubbing etc. i notice at the moment my wheels stick out a tad already, is this because they are 7.5j. and also since i have put these wheels on my car it has more of a tendancy to pull over the road, like pick up every single bump, would wider/ bigger profile tyres sort this or is it these style of wheels are to wide for the car and would be better with wheels that are 7j. any info would be appreciated, thanks.
