This is a pretty good list (either to starboard or port !) of the various
factory felgen wot phytte sundry BMWs .........it goes on for pages and
pages !!

If you cant find it here , it hasnt been invented yet !!
Remember that BMW changed the centre-hole size on factory wheels in the
early 90's (E32 and E34 ..7-ser and 5-ser were the first pair ) so when
fitting to earlier cars they NEED hubcentric rings to enable them to be
balanced properly .............or hubcentric spacers if they're a different
offset . DONT buy cheap non-centric spacers and then wonder why your wheels
dont balance !! ..and DONT use stock-length wheelbolts when you have spacers
behind the wheels , you need at least a 'diameter-and-a-half' of bolt
extending through the wheel and spacer combo . DO torque those bolts too !!
It is a good idea to put a SMALL amount (repeat after me "small =a tiny bit
not a bloody great glob !!")of wheel bearing grease (good and sticky !) into
each stud-hole ......preferably before putting the bolts in !! - plus put a
light smear of it onto the mating faces where the wheel bolts to the
hub-face and where the stud/bolt taper fits the wheel ......it helps to stop
corrosion between dissimilar metals, thus ensuring you can get the wheel off
without resorting to kicking it on a cold rainy night when you're dressed
for dinner and only have the factory (killer !!) jack and lug-wrench (you DO
keep a disposable paper coverall suit rolled up in the spare-wheel dont you
?? .....gloves ? ..cheater pipe that you know fits the factory lugwrench and
clears those fenders ?) . Remember ...........If the tire-jock puts 200 ft
lbs of twist into the bolts with his airwrench and you only have a one-foot
long lugwrench you've gotta weigh at least 200 lbs to even have a hope of
getting them loose ........on that factory jack ? in the rain ? dressed for
dinner ?? ..got the message yet ??
The relationship between wheel diameter , wheel width and wheel offset AND
tyre-width that will fit under various fenders AND clear the strut-leg on
the inside of the tyre AND allow for full lock motion of the steering is a
complicated one due to the angle of dangle between the strut-leg and the
wheel-axle . It is NOT as intuitive as it might at first seem so do be
cautious when buying stuff you cant test for fit first . Remember , just
because a wheel without a tire will bolt onto the front strut does NOT mean
it will when you stick a big fat gummi on it .
CHEEP WEELZ ..........those of you with 5-bolt wheels should remember that
if you want a set of really cheap wheels -say for a set of track-only
tires -there are LOTS of Chevy wheels that will bolt onto BMWs !!
............there's a lot of funny looking camaros at BMW track days
sometimes . One thing about GM wheels , they may not be pretty but they are
always hellfer STOUT for when you take an 'off ' ...and they look great
covered in brake dust !
This note ISNT intended to start a firestorm, just simply to relay useful
info gleaned from 37 yrs of messing with BMWs . If you dont want to put
wheelbearing grease on the back of your new wheels , I dont care . If you
dont know what a smear of grease looks/feels like then you either need to
learn or not mess with it . If you prefer to use titanium di-bongide or
scented musk oil I dont care . This note purely and simply relays info
regarding what I do in the hope it might help you in what you do . Nuthin
more !!
Enjoy your new wheels .and keep them off the kerbs !!
