M3 wheels questions
My M3 is on order so i have been looking for aftermarket wheels.
I decided to go aftermarket because the 18s look crappy and i dont think the 19s are worth 1200 and everyone is saying they are 2 heavy. Besides 90% of the M3s out there will have the oem 19s and i want to be different. So i decided to get the oem 18s and put the 1200 towards the aftermarket wheels. I decided on the SSR GT3s. in 19 inch. How do you guys think these will look on the E90 M3. I saw them on an E46 in person and they looked amazing. I want to go one size up with the tires. I am considering 255/30s up front and 275/30s in back. Do you think this size will cause and rubbing or other problems. Last question the SSR GT3 wieght 27lbs. that seems light for 19s. Does anyone know the weights on the oem 19 and 18 inchers Thanks |

Did you check out the wheels and tires at www.tirerack.com ?
I think that the stock 19" wheels weigh about 30 lb. The BBS wheels look great! |

i have the ssr's on my e46 m3 right now. imo they're the best looking wheels out there for this car.
i'm looking to get the 08 m3, and i'd really like to put the ssr's on it, but there's no info on whether they would fit or not. any ideas? they're 19", btw |

Your rears may be ok, but the front will probably sit in (depending on what offest you are using). The factory offset on the new M3 is ET29 on a 8.5 front wheel.
To the OP, since you are still in the process of looking for wheels, I would wait another month or so, so that further test fitting on the car can be done and some further fitments can be confirmed. The M3 will be a whole new fitment, just like how the current gen non-M 3 series was a whole new fitment, especially on the rear. |

Wheel stuff
Quote:
30 lbs is pretty heavy for a 9.5" forged 19. I wonder if that's rumor or substantiated. Tomorrow I may weigh the assemblies; since Michelin lists the tire weights (24# F & 25# rear), I can caculate the wheel weight, at least to the closest pound.

Here's a photoshop I did a year ago when the concept first rolled out with SSR GT3's. I agree it's one of the best wheels I've seen on the E46. Not so sure on the E92. Maybe it's just my horrible photoshop!!

...Oh, the info is there. Here's a freebie for a newbie, and my good deed for the day: First thing you'll need to do is let us know what size your wheel is... ...yeah, I know you're thinkin' "...but hey, I already told you, they're 19"!" But find out what the width & offset of your wheels are and compare to stock, if you can't do the math by yourself, I hear the Tire Rack linked above has a "wheel & tire size calculator." Next, read through the sticky of this very wheel forum and you will find the stock specs...(for weights, you'll want to search this forum using google) Now... DO WORK!

Stock 19" wheels weighed
I pulled a front & rear 19 today. Measured the wheel/tire weights on a $900 Swiss digital scale. I weighed them 3 times each. Tire weights are listed on TireRack.com as 24# F & 25#R. Here are some pics; I also photographed the calipers/suspension, which I will post later.
Front: 47.0 - 24 = 23# wheel weight Rear: 51.5 - 25 = 26.5# wheel weight I suspect the tire weights are approximate, so I would guess the margin of error for this calculation is +/- 0.5 lb. or so. The difference between front and rear is a little surprising.

Nice Greg! Thanks for verifying this for us.
I'm jealous that you're able to have some fun "working on the car" (last pic) ...can't wait.

Sweet! Thanks Greg.
I don't find those weights to be all that bad. Definately less than the 28-30lbs people were incorrectly tossing around. You said you find the difference in weights to be suprising even though the rear wheels are wider? Lovely pictures. Can't wait for the suspension pics.

My RAC wheels are only 1.3# difference F to R. I was expecting maybe 2# difference. Of course, if the tire weights are rounded up and down a bit, that could make difference of a pound.

I highly doubt that BMW would provide 23 lb wheels...I think that they are heavier. The info on Tire Rack is not always correct as those ugly Breyton GTS wheels were said to weigh 20~ lbs, but weighed 24-25 lbs...so until the tires are weighed independently, I cannot believe the 23/26 lb wheel weight.
No offense to your scale or your car or the time you took to do this or tirerack.com, just being analytical. |

Thanks a bunch for providing the numbers Greg!
Yes, they seem light, but why are people surprised exactly? They thought that BMW was going to ship a $65k car with optional forged wheels that weigh 30lbs? I don't think so. The BBS wheels are 20-22lbs so 23-26lbs for the OEM wheels are totally reasonable. Now that we know the tires + wheels weigh, we'll just need to be patient until someone weighs the tires alone. I'd say the error margin on the tires might be more like +/- 1 lbs, but not more than that. You'd figure Michelin would know how to weigh its product.

The information came from a German "wheel catalogue" feature. Thanks to Greg's efforts we know that information was wrong. Best regards, south

Again, no offense to anyone, including BMW...they are a company that wants to minimize costs, and by making the wheels heavier, 99% of buyers would not notice, and, in the process, wheel-related incidents would be minimized. |
