Suspension Noise problems of the 2004 Infiniti G35

Bought this car used less than 2 weeks ago and drove it back from chicago 6. 5 hours. Car had a terrible tire hum/vibration which seemed to be coming from the front right and was almost unbearable. I chocked it up to maybe the tires not being rotated on schedule and decided to purchase 2 new tires for the front ASAP. I have had the new ones on now for less than 100 miles and the passenger side has already started feathering. So I figured it was an alignment issue, had the alignment checked, which was on point, and no issues could be found with the suspension during their inspection either. Decided okay, must be the tire or the rim so I swapped the front right with the left and in one (1) day (20) miles it too has started to feather and I still get the same hum/vibration feel and noise. The noise and vibration is pattern like in nature. So I decided hit the good ol interweb to research this and find that I'm not alone. Seems a good many of owners complain about the very same issue which is very common with the G35 and it's cousin the Nissan 350z. Apparently, it's acceptable and you're lucky if you get 12000 miles out of tires and the noise and vibration is just one of those things owners have to deal with. I'm sorry but I find that to be unacceptable! I understand there's maintenance cost involved in owning a car, new or used, but tires are not cheap in the first place and having to purchase a performance tire to boot only stings the pocket that much more. Not to mention a safety issue. Infiniti should really look into this and find out what the real problem is and fix it. One shouldn't have to worry about tires going bad so quickly, much less have to worry about budgeting for a new set of tires each year or sooner because they're wearing to the point of concern of safety.
