i just got a set of wheels and put the stock lug nuts on them, they seem to have fit fine i was just worried that they might of not threaded in enough. i want to say there was about 3/8 to 1/2 inch engagement. here are the wheels http://wheelstudio.com/catalog/product_info.php?products_id=9093&vehicle_make=Inf initi&vehicle_model=G35%20Coupe%20>%202003-2007&t1=245-35r19&t2=245-35r19&t3=255-30r19&pkg_tire=16234&staggered_id=9090&stagger_tir e=16236&tr1=285-35r19&tr2=275-35r19&tr3=285-30r19&staggered=yes

any help would be appreciated since i drove approx 20 miles on them at about 40-50 mph. if they were gonna fall of they would of by now right?
i replaced the stock 225/50/17s.

 

looks like they should fit fine with those wheels, but remember to re-torque them after 25 miles of driving...
