Aftermarket rims vs. BMW rims for winter
I am considering buying Moda Rims for the winter but am concerned about the safety factor.
I have read, probably on this forum, that BMW rims have unique geometry to better secure the tire to the wheel should the tire lose pressure. Does any one have an educated opinion on this? Attached are images of the Moda rim I am considering, the BMW 308 rim and a 535 xi sporting these wheels. The Modas are heck of a lot cheaper than BMW rims and I don't think they look all that bad. |

just remember that BMW has a large marketing department for a reason and 85% of what they say are "features" are rubbish! did you know that a white iphone has less glare than a black iphone, so you should pay me $50 more for the white model Apple don't get any ideas with my example!
by the way those rims look nicer on the car picture than on the individual pic. I think this is the case with most wheels, even with teh visualizer that tire rack has, I think a lot of them look bad when looking at a 2D picture online, in person they look much nicer. as far as generic wheels go, I bought a set for my C63 that actually look a lot like the stock wheels (didn't even mean to do that) they were $600 for the set, have had them 2 winters and no issues! the markup on wheels is insane when you buy factory OEM |

I am going to go with 18" from tirerack with Michelin winter run flats. Total cost of around $2100. I think for the summer I am going to just leave the all seasons on, hate to do it but I also don't want to spend $1400 for the performance tires and have a set of all seasons going to waste.

In this case, what BMW is telling you isn't rubbish. BMW OEM rims conform to the EH2 (Extended Hump 2) wheel specification, which are specifically designed for run-flat tires. While normal rims have a single ridge (or hump) which holds the inflated tire in place, EH2 rims have a second ridge which holds the tire in place in a zero-pressure situation (such as a blowout). Without this additional ridge, the tire will likely separate from the rim if all pressure is lost.
You'll have to decide if that's an important feature or not. Regardless, without an EH2 rim, if you have a blowout or otherwise lose most of your air pressure, you'll obviously be waiting for the tow truck. |
