2011 550ix M Sport Wheel Size Question
The standard rim for this model is the 19" 351 M Wheels. What are the actual size specifications for this wheel?
I'm interested in replacing these rims with a set of Hartge Classic II rims of the same size. Does Hartge make a matching size in the Classic II's? Assuming that Hartge has the Classic II in the same wheel size, could I install the tires that come with the 550ix on these wheels? Thanks for any assistance offered. |

Thanks Bobblehead for the prompt reply.
Question...looks like these 19" Classic II's would be close to the standard rims: 19" Hartge Classic 2 Front & Rear alloy wheels: 19x8" ET37 Tires: 245/40/19 However I noticed 2 specs that are different: 1. The 19" Classic II's rims are 8" wide compared to the standard 8.5" rims. Any issues with them being a .5" less? Need any offsets? 2. The tire specs for the 19" Hartge's are ET37's vs. the standard ET33's. What's the difference? Can I use the ET33's that come standard with the Hartge 19"? |

The 245/40/19 should fit the Hartge 8" wide without any issue. Offset - as indicated.
Offset is only refer to the rims ... has no relation to the size of the tires. Based on the Hartge spec. - (in comparison to the stock spec.) .... The new wheel setup will give you: 4mm closer to the suspension/brake component - which is within acceptable allowance to clear the mentioned. Before you proceed to buy the rims, you should also double check with the wheel/tire shop to make sure of any (brakes/suspension) clearance issue. |
