so i put 73mm center bore wheels on. original bore is 67mm. the new wheels use cone seat tuner lugs so i assumed the wheels were lug centric. while driving at and over 60mph, the car vibrates like my girlfriend's favorite toy. has anyone else experienced issues with hub centric wheels? i put hub centric rings on today but havent driven above 60mph yet. gas is expensive and the freeway is far from me. ive read that by not having the hub centric rings, vibration is a symptom and the bolts can actually bend and possibly break off. more info please. thanks.
