Hi guys, Long time lurker, first time poster. Have a wheel swap question of different size widths. I have a bog standard BF Falcon Wagon 2006 on 215 60 R16 ugly steel wheels with even uglier hub caps. I bought FG Falcon 17" Wheels with Dunlop SP 245 45 R17 tyres from Gumtree on the cheap. (Good deal at $400!) 85 % tread, no obvious scraps on wheels. Cleaned up real nice. 1. As the FG Falcon 17" tyres and wheels I bought are 2nd hand, excellent near new condition but still 2nd hand and much wider then the current 215 60 R16 steel wheels, should I do a wheel balance on all of them BEFORE fitting them to the car or should I fit it to the car and then take it to a shop for a balance? I don't want to damage the tyres. I was going to fit the FG wheels on the car myself and then drive the car to Kmart Auto for wheel balance and alignment but better to ask the guru's first. 2. I didn't get any nuts with the wheels, will the standard nuts on the current steel wheels be ok on the new FG alloys or should I get new nuts? Sorry if my question is extremely newbish, first time alloy wheel buyer. Thanks, Turbo Dreamer.
