My gut is I don't think so, I think they would rub. At least when you went over bumps, etc.

Are you lowered with coilovers or springs only?

Please let me know if you can, where you purchased wheels. From what I see, the fronts are 8.5 and not sure if a 275 will fit.

Do you think the tire size will work with a 540I? I dont want to lower it. Also it will be msport suspension. If I am not mistaken, the ride height is the same. I want to do the 29535/20 for the rear.

I think it should work the same as the M550. However, I had to change out the 295/35/20, because the ratio was too different from the factory sizing and it threw off the all wheel drive system. What did work, was either a 295/30 or a 305/30. I'm running a 275/35/20 in the front. Hope that helps.

Thanks man! I don't know the offset, but the wheels came off a new 7 series.

Your car looks great. I tried to find the wheels that you are using and as far as I can find, they are 20x8.5 and 20x10. I used the 86281 and 86285 numbers to search. Can you steer me towards the 20x9 and 20x10.5 wheels? Thank you.

Thanks! I purchased mine from a wheel store on eBay. I just looked back at my transactions so I could give you their details but it's no longer active. They were out of California. I just searched "BMW 86281 " on eBay and there were some sets listed, from wheel stores in CA, but although it said staggered set, it didn't state the width. I'd suggest messaging one of those companies and see if they have them in the size and finish you want. That's what I ended up doing previously. Hope that helps.

I just purchased the same 20inch 7 series 648M wheels for my M550i. Are you still using rear 305/30 and front 275/35 tires? I haven't purchased tires yet and have been researching online. I didn't know I could go that wide front/back. Have you had any issues with rubbing at all? Is your car lowered?

I can't wait to get these new wheels put on my car. I am not a fan of the stock wheels the M550i's come with.. they are such a pain to clean!

Thank you in advance, your M550i looks amazing! -JP

Congrats! Yeah, the stock ones get dirty quick, you won't notice the dirt near as much with these. No, my car isn't lowered and I'm still running those tire sizes. No issues with rubbing at all; see tire specifics below.

I want to go with the same sizes on my M550 but I’m wondering how they will hold up here in NY with all of our wonderful potholes...

TexasM550, do you have the dynamic handling package? If not, does anyone know if having that option limits max wheel and tire size?

Apologies for digging up an old thread but it has some extremely useful information in here.

I own a 2017 520d G31 (Touring) and I have the chance to buy some M5 706m alloy wheels and tyres.

Will 275/35/20 front and 285/35/20 rear wheels fit? Alloys are 9.5J ET28 & 10.5J ET28.

Judging from your previous comments, they should fit? I just wonder if the suspension is at all different.

I'm in the same dilemma. I've got a set of 20x9 er25 and 20x10.5 et38 coming in and trying to decide on tire sizes.

either 245/35 and 285/30 or 255/35 and 295/30

I don't want stretch or donut look. The wider set seems to be flush sidewall which fit well but I don't think looks the best. The skinnier set seems to curve in a little at the sidewall with minimal stretch if any, but looks better. I can't seem to find many consistent pictures of the 245 and 285 tires. Some will show they are too stretched and some show little to none. I think it based on tire manufacturer a bit.

I went with this set up and I get sporadic rubbing in the back if I go over any dips at speed. not recommended. 295 probably would have been perfect. pirelli p zero tires. I also this the front tires are too tall. a /30 would have been perfect.
