Hi there - I'm new to thjis and could really do with some help before I part with some cash to buy some alloy wheels. (I have checked the chart from the previous posting but can't make head nor tail of it). Put simply, I have a 2002 (W202 I believe) C22o Cdi Classic. It has the small 15" wheels and I would like to upgrade them. Can someone tell me if these will fit : 17" Alshain Alloys 2 x Fronts 7.5J 225/45/17 2 x Rears 8.5J 245/40/17 Many, many thanks in advance.
