M3 rims feel wobbly??

[prod0660]

hi im running a 528i (99) on 19 e46 m3 rims al around. fronts are 19X8, and rears r 19X9.5 (stock #s) one of the rims cracked bad so i bought a new rim ( m3) its still 5X120 and 19X9.5 but the inside diameter of the rim ( where da BMW center cap would go ) was off by a few MM. why ? i dont know i thought they all came the same, so i took it to a machine shop and the guy left it just how i had the older rim ( the one that cracked, same diameter and everything), i mounted the rim on no problems, nice and tight no play or looseness. then i drove it around the block and it felt very wobbly in da back.. only after 30mph+. could the rim just need to get balanced? or is it something bigger. also the back tires are 275,35,19. incase its needed..thanx,(very noob ?, but last thing i need is more money dumped into the car

did you balance the rim/tire combination after mounting the tire?

dont think the m3 rims are hubcentric to your car

[Dane083]

I know its stupid but check your subframe, when mine broke the car was really hard to drive

Balance your wheel/tire.

check if the wheels are balanced right, and make sure you tightened the bolts.

you said that the centrebore of the wheel is way off by a few mm's.

YOU NEED HUBCENTRIC RINGS FOR YOUR WHEELS! i gurantee it.

wobbles

The rim and tire were balanced before the bore ..even if the wheel got machine while it was on the tire on its still needed to balance?

[Zic]

Yes go and balance it again to make sure. i would bet 5dollars that is it.

Apparently town fair tire gave me a new tire that waS damAged .so tomorrow everything shuld be settled ...thanks everyone for the amazing feedback and suggestions

Check that your wheel was properly bored out by jacking up the car then use something to reference where the edge of the rim is by barely contacting it. Rotate the wheel slowly while looking for any changes in the rim's radius from the center of the hub. It's kind of hard to put in to words but is a simple check that eliminates the possibility of the wheel being bored out off center.
