hmm, well I have my stock wheels which I am in the process of fitting now, yeah my nuts are tight that was the first thing I checked when the noise appeared.. the tyres are at about 50% treade and look in great shape, I dont do any circle work or anything, weird it just started doing it one day. the noise isnt really loud enough to take a recording of, but I can feel it a bit through the car, its very noticable at 80, and when I slow to 60 with my foot slightly on the brake pedal it seems to get a bit worse before getting better, im thinking maybe warped discs? im not to sure, any more info you guys can give would be great, ill keep you updated with what I find with the stocko's, cheers guys
