M3 wheels as winter rims for the X3 35i?
Featured on BIMMERPOST.com What do you guys think about these rims for the X3 35i as the winter setup? Tires would be either the Pirelli Sottozero or the Dunlop WinterSport 3D. Not bad price so I'll probably pick em up. |

I think they would look good. I like the multi-spoke wheel.

I don't recall every seeing that wheel on an M3. They look more like 7 Series wheels. That aside, if you like 'em get 'em. They wouldn't be my first choice for a dedicated winter wheel because they will be a bitch to clean. If you don't mind spending all winter with filthy wheels....
All that said... you'd better check the hub bore and ensure that it will fit the X3. Not all BMW wheels are interchangable between models - in fact, most are not. Find out what style wheel it is and check RealOEM or other sources first.

FYI: Basic wheel specifications for the X3(F25) chassis are: Bolt Circle = 5 X 120mm Offset = 45mm (43 to 47mm acceptable) Hub centering Bore = 72.5 mm (hub ring dia. = 72.47mm) Bolts = M14X1.25 Conical seat, 17 mm heads (Note the X3(E83) uses M14X1.5 bolts) Minimum bolt engagement = 9.5 turns The bolt engagement spec is very important and is often overlooked. Some wheels have different hub thicknesses, so use different length lug bolts. If the replacement wheels are even slightly "thicker", you need longer bolts.

Ok, cool. I know about the first two line items but am not aware of the other three. Good to know.
Right about the wheel being harder to clean in the winter though. Simple is better probably. Fewer spokes, more open spaces. Thanks. |

Yeah, my X5 winter wheels are much more "plain" and easier to clean than the summer M wheels. They are still OEM BMW wheels, made for the X5, but non-staggered and wearing all seasons. A lot of grime gets on/in the wheels in winter, and I obsess too much to tolerate it being too dirty... so I like something easier to clean in cold weather.
Also, consider checking eBay for a set of X3 pull-offs. They are bound to start appearing soon.

Alright so I can buy BMW OEM wheels that is designated for the F25. I can also get after market items that will work (Tirerack and local shops). I saw a set of BBS 18" and the offsets are 40 rear and 35 front. Spec say 45mm offset for the F25. Would putting in spacers make the set up work geometrically?

What is the width of the rears? If they are significantly wider than 8 inches, you will have better geometry with a 40 mm offset than 45 mm. If they are narrower than 7.5 inches, a 5 or 7 mm spacer would restore near perfect geometry. However a spacer that thin may be hard to find. Commonly, they come in 12.5 mm and 19mm. On the other hand the spec is 45 +/- 2mm so 40mm with 8" wheels is very close (3 mm error), and shouldn't create any real problems. |

i don't think these are m3 rims. i think it is replica m3 wheels. the m3 wheels suppose to be polish and shiny for 19inches. the 18 inches has real spoke, these rims are not real spoke. plus, the little m sticker is missing.

Non BMW rims are no problem, does not have any impact on warranty at least not in Norway Last edited by X3andZ4owner; 07-17-2011 at 01:45 AM.. |

The replica look good. Saw some nice reps on a 3 series. Hmm, would they make good winter wheels? Guess for the price doesn't matter. Reps vs Moda and other non-OEM wheels.

They are in fact M3 rims as part of the 2010 E92 LCI, which includes LED taillights. They are not the only M3 rims. That's why wheels are among that which are referred to as options.

The bolts must match the hubs so M14X1.5 bolts are used on the E83 as stated. For a F25 chassis you MUST have M14X1.25 conical seat bolts. The bolt thread length for the OEM wheels is 25 mm. The length must be matched to the wheel. Different wheels require different length bolts. I have wheels which use 25mm bolts and also winter wheels that need 30 mm bolts. The length must be such that when the bolt is fully in the wheel, there is 12 mm of bolt thread protruding from the backside. The bolt must engage 9.5 turns when torqued. M14X1.25mm (17mm head) lug bolts are available from TireRack. Last edited by Lotus7; 09-07-2011 at 07:55 AM.. |

The shortest thread length TR has for a M14 x 1.25 lug is 27mm. I'm now thinking that I'll purcahse the lugs at time of installation. My original plan was to purchase the tires and lugs together for installation at a later date as winter approaches.

All you have to do is take a OEM lug bolt off the car and stick it into one of your new wheels. then measure the length of the bolt (the threaded end) that protrudes through the wheel. If it's more than 12.5 mm , but less than 15 or so, you're good to go. If it's less then 12.5 mm you will need longer bolts. The 27mm bolts from TR are essentially "stock" length, so offer no advantage if your wheel centers are thicker than stock. |
