Hi,I currently have 225/50R16 run flat tyres on my BMW 3 Series 320D E90 (2006) and I am looking to get some new alloys. I'm looking at getting 16 inch BBS SR Alloys. http://www.wheelbasealloys.com/alloy-wheels/bbs/sr/grey/16-inch They have a width of 7J and an offset of 35 to 48, but is this ok for the size tyres I currently have? Any helps appreciated, Thanks.
