Trial wheels/tires- what works?

Anyone yet to test fit anything aftermarket, wheels sizes, offsets and tire sizes?

I am considering the 2016/17 7 series 648M wheels, 20x8.5 et 25 and 20x10 et 41. I want a more aggressive wheel, pushed out and slightly wider tires, same profile. Will require some test fitting obviously to avoid rubbing.

Would help if anyone has started down this path to share what has worked and not worked both in terms of wheel sizes and offsets as well as tire sizes.

I'll probably be going with a after market wheel. I'm like you I need something a little more aggressive. There shouldn't be any problem doing this. The M5 I'm sure will certainly have much bigger Wheels and fatter tires than what comes on the 540. The body is the same and it has AWD so there shouldn't be any rubbing with the same size or narrower wheel/tire.

Jay, I couldnt agree more, while the OE 19s are really nice looking, they are just to civil and plain. Just something a little meaner looking, fatter tires as well so the driving and handling are more connected.

I ordered my car in march it's built just waiting to be shipped to the U.S. I spec'd it with the 20". 759 rims they are a Ok looking rim but it really doesn't make the car "pop" to me. I like the 668 wheels that come with the 550M but if I'm going to pay a premium price for that wheel I might as well get a rim that everybody doesn't have thats a little bit wider so the car can have a meaner presence. I'm thinking about the exact same wheel size you mentioned. Tire size will be 255/35/20 front and 295/30/20 rear. I believe this should fit the car as I don't believe the M5 will have anything narrower.

Jay, I'll let you know hopefully by late next week. I am either getting the 668M and then putting on bigger, wider tires than the OE or the 648M from the 7 and had thought of 255-35 fronts and 285/30 Rear. That one will need to play around with. One of the guys on here is waiting for his car back and has 20x9 et 28 with 245/35 fronts and 20x10 et 30 with 285/30 rear.

I quite like the idea of running 245's at the front with 285's on the rear to match the height of the tyres, the 275 tyre that comes at the rear of G30s is quite a bit shorter than the fronts and creates a bit of a weird gap and stretch I think. To do a 285 at the rear though you need wider than the rear 9" stock rim. As such I think that the various OEM G11 wheels will become popular options on the G30. A little bit of info for you all:

Every G30 staggered set is 8" and 9" with offsets of 30mm front and 44mm rear

G11 19" staggered is 8.5" and 9.5" with offsets of 25mm and 39mm

G11 20" and 21" staggered is 8.5" and 10" with offsets of 25mm and 41mm

Completely agree, I bought a set of 7 series take offs, the 648m in 20s. Had some accent painting done so they look more like my M4 wheels. Tires come in Wed so will be going with 245 fronts but testing the 275/30, 285/30 and 295/30 to see what fits and what looks the most proportionate. The offsets are 25 front and 41 rear as you said, which will definitely work and push the wheels out a bit so they arent so tucked in like the oem 19s on now. Will post pics later in the week. Itching to get them on.
