21" Wheels on 2018 M550ix

rvissy · 05-02-2023, 02:05 AM

Anyone put this on their car?
Rear: 275/30 R21
Front: 245/35 R21

Worried about rubbing and any potential issues with wheel diameter messing with the x drive

21” is the only way to fly on G30.

Looks awesome - What size tires do you have on there? And no issues with wheels rubbing?

Marior20 · 05-02-2023, 12:26 PM

Tires are 245/35/21 and 275/30/21 , Lowered on KW V3. No rubbing at all.

I had the M brakes (made by Brembo) powder coated in McLaren Diablo yellow with black Brembo stencil.

Thanks! 295 rear, 255 up front. Not lowered on OEM dynamic suspension. NO rubbing at all.

Looks good but I mangle my 19” rims in NY.

Enjoy

What profile - I just went order some wheels and the guy thinks they will be too tall. Looks like your tires are 295/25 or 295/30?

Igor_M5 · 05-24-2023, 05:21 AM

21” no problem, 21x10 all around no problem

Ok maybe some problem with stock fenders 👀

What are those wheels? Absolutely love them, could you provide manufacturer and model name?

F90 fenders, F90 control arms, knuckles, etc.

OEM

Mind you, that’s with a 20mm spacer (bolted) 👀

Easily fit a 11” in there especially with a smaller profile tire.

What are your tire specs??? 285 fronts?????

Also what are you lowered on?

lnxguy · 07-09-2025, 11:15 AM

Hard pass on 21s. You'd be on rubber bands and require perfect roads with no pot holes lol.
