BMW Wheel Weight - Style 351M?

I started to look at winter wheels at Tire Rack for my 550 and started noticing the big differences in the wheel weights. Does anyone know how much the Style 351M wheels (that come with the M-Sport package) weigh?

I have no idea but I too would kill to get this info. My car is stuck in Paris for the last five weeks or else I'd get you this info asap. Hopefully someone here with that wheel can step up and get it weighed.

Hi guys - I'm no expert, so please explain why you're worried about the weight of the wheels. Surely you'd save more weight by taking a good shyt than worrying what different wheels weigh? :-)

Again, apologies if I'm completely missing something!

Look up unsprung weight then get back to us. I'll look for a good link explaining the benefits but I'm on my iPhone right now and it's a pain.

A quick look at TireRack has 19' rims weighing 20-30lbs, and 245/40R-19 tires weigh 24-29lbs. Assuming the 351's weigh 25lbs and the stock Goodyears weigh 29lbs, I could potential save 40lbs of unsprung weight. If the 351's are closer to 20lbs, then a lighter set of tires would be less costly option.

I have the Style 351M Wheels as winter wheels and they are awesome. For the weight call Gary Romani at BMW of Newport Rhode Island. I bought my wheels from him at a substantial discount.

I would be surprised if it weighed anything below 25lbs and would guess about 27-28lbs your right some 20lb wheels and PS2's will save 40-45lbs which makes a substantial difference in the handling and ride and a slight improvement in acceleration.

The BMW 351M Wheels are 18" wheels.

Then he must have the wrong reference # he means the ones on the white car in his signature.

Maybe not. Those are 19" wheels which are not good winter wheels. 18" wheels are the largest practical winter wheels based upon winter tire availability and physical wheel factors for driving in snow conditions.

I'm looking at 18's for my winter wheels, but I'm curious how much the stock set-up weighs. If the stock set-up is 10lbs per wheel/tire combo heavier, I might just replace the summer set too. If the 351M is a decent weight, I would consider buying 351's in 18" as a snow set-up.

That's an article that illustrates some of the possible benefits. Now obviously considering the source you have to take this with a grain of salt BUT in the near future I will put this to the test with my own 550I on the dyno and we'll see if it does make any difference.

As a comparison, I weighed my 335d wheels/tires.

OEM set-up
18" BMW Style 195 Wheel = 27,28lbs (front,rear)
18" Bridgestone RFT = 25, 27lbs
Totals = 52, 55lbs

Current 3 season set-up
18" BMW Style 195 Wheel = 27,28lbs (front,rear)
18" Continental Extreme Contact DWS = 22,23lbs
Totals = 49, 50lbs
Net Savings 16lbs from OEM

Current winter Set-up
17" Rial Salerno Wheel = 23.5,23.5lbs
17" Dunlop SP Winter Sport 3D = 23, 23lbs
Totals = 46.5, 46.5lbs
Net Savings 28lbs from OEM


Now looking at several F10 set-ups

OEM set-up
19" BMW Style 351M = 27,27lbs (Just a guess)
19" Goodyear Excellence RFT = 29, 29 lbs
Totals = 54, 54lbs

Potential Winter Set-up
18" BBS RGR = 19, 19lbs
18" Dunlop SP Winter Sport M3 = 26,26lbs
Totals = 45, 45lbs
Net Savings 36lbs from OEM

Potential 3 season set-up (Option 1)
19" BBS RGR = 20.5, 20.5
19" Continental Extreme Contact DWS = 24,24lbs
Totals = 44.5, 44.5lbs
Net Savings 38lbs from OEM

Potential 3 season set-up (Option 2)
18" BBS RGR = 19, 19lbs
18" Continental Extreme Contact DWS = 24,24lbs
Totals = 43, 43lbs
Net Savings 44lbs from OEM

How does that old saying go; If you want to get something done right, you've got to do it yourself?

Okay, I have my car and I have weighed the wheel and tire set-ups.

OEM set-up
19" BMW Style 351M = 33.4,33.4lbs (What was left over)
19" Goodyear Eagle LS2 RFT = 30, 30 lbs (From TireRack)
Totals = 63.4, 63.4lbs (Weighed)

Actual summer set-up
19" BBS RGR = 20.5, 20.5 (From TireRack)
19" Michelin Pilot Super Sports = 25.1,25.1lbs (What was left over)
Totals = 45.6, 45.6lbs (Weighed)

Net Savings 71.2lbs from OEM

Based on the deltas in tire weight alone, the 2wd set-up would be an additional 4lbs.

The 351's are made in Hungary and the Goodyears are made in Germany.

Only time will tell if my lightweight set-up will have better or worse reliability than the tire bubbling and rim bending issues that the OEM setup is experiencing.

That site seems to say that the 8.5" wheel weighs more than the 9.0" wheel?

Great Information. Was your 550 before staggered and rear 19X9 rims versus the 19X8.5 front. I am just thinking the weight on the rears would be different. Thanks for the great post. Do you by chance have the offsets for the OEM 351m either size 19X8.5 or 19X 9?

My xDrive was non-staggered from the factory.. The 351m 9" rears don't appear to weigh much more, but I don't have the reference readily available. The offsets are 33 for the 8.5" find and 44 for the 9" runs.

I have 19" Blizzaks coming on Avant Garde 359's from PY Speed. I did reseach and found that there was no percieved difference in snow between the 18" and 19" I wanted to keep a decent look since we have these damn things on for 6 months out of the year in MN

I'm looking to buy a 528i and was planning on trading the 350M rims for the 351M rims through the dealer. The unsprung weight issue though makes me believe that perhaps I should go aftermarket instead. I think the 351M rims look great but they are heavy and part of my reasoning for going from a 550i to the new 4 cyl is fuel savings. A lighter rim would probably achieve greater savings than the 18" 350M rim.
