Hi, I have an order for a 2025 50e, been reading the forum to weed out troubles or complaints about the model like I always do before a purchase. I do see a lot of complaints on CEL issue which I home are fixed on the MY25 but also seen some complaints about tire noise on the 21” wheel pkg. Is this truly an issue o isolated, should I stick to the 20”? The 21’s make such a difference in looks (more agresive) Thanks

i had 21" summer performance originally on my 45e but switched to 20" all-season. road noise wasn't the issue, but rather, availability, all-season choices and overall convenience come replacement or repair time.

20" can still look pretty aggressive

I have the 21" rims that came with Hankook Ventus S1 EVO3 SUV tires, and road noise has never been an issue. I checked and do not have the dampeners installed either.

The only noise heard is from the side windows due to not being able to order the acoustic glass.

Good to know! Thanks

I have 50e with OEM 21 inch wheels. No road noise issues. Very quiet.

I have the option 22's on mine and the absorbs the noise really well. The drive does not appear to be impacted

We just picked up our X5 50e two days ago and she is beautiful. We went with the 20" wheels. I will say that the 20" wheels look alot better in person then i thought they would.

But with that said, we always knew we would buy aftermarket wheels either a different BMW OEM wheel, replica wheel, or Rohana/Brixton wheels but they will be 21" wheels. To your point i think 21" wheels are a great middle ground of looking good, filling out the wheel well and not sacrificing ride quality with 22" wheels and increased damage possibilities with pot holes.

We live in Denver, CO so the car will be seeing lots of mountain driving and winter driving.

Is there a difference in the outside diameter of the tire?

to your point (in bolded text above), there is no difference with 21" filling out the wheel well more than 20" as the diameter of the tires is the same.

21" just looks bigger because they take up more room inside said diameter at the cost of reduced sidewall

This is what I thought. There was a prior comment about “filling the wheel well” which I think is not technically correct (though you are right that the visual impact of less black rubber sidewall).

I run summer tires on staggered 741M rims and winter tires on square 740M rims. If or when I order a new one, I’ll probably order it with 740Ms, and run a square set-up all year round, for comfort, looks, and especially tire options….

Greatly appreciate you dropping some knowledge on me, that's why i read these forums, to learn

Well hold up a second, the picture you provided shows a deference in circumference numbers, which means there is a difference in diameter. One cant change without the other.

So technically, the 275/45/20 tire has a bigger diameter which would fill out the wheel well more then the 275/40/21 tire lol. And yes im aware were talking mm here but they are not the exact same...

Thanks for sending me down a rabbit hole this morning

the circumference listed is the rolling circumference which is not perfectly round due to vehicle weight, so there is no direct correlation between that and the diameter. while the 20” tire technically has a larger rolling circumference of 0.3” than the 21” tire, it will not make a visual difference.

They didn't change the definition of circumference. . All measurements/calculations are done off of a vehicle.
