Hi everyone!

I read most reviews from this forum and watch most reviews from YT, however I don't think I found a single review talking about the range with the 20" 862 wheels.
Am I correct?
Any of you might have a link of such a review or maybe a real life test drive?

BMW says 488km WLTP (which is 50km more than the 20" 868 M sport and only 25km less than the 18").
In theory, the 862 are a nice comprise between looks and range. This is the reason I chose these. However, I don't see them very often in reviews.
Thoughts?

Following. I’m interested to see if there’s a 20” wheel option with good range and comfort. I chose 19” for my M50 but I can change my order.

The 862 wheels are not optional in the USA i4, but can be ordered at your dealer as accessory.

If I order a car with 19” tires, will 20” still fit if I get them later? (someone mentioned a while ago that the structure of the car around the wheel area may be different for 20”)

That depends on the width of the tires. If for instance you take the 868M wheels they have a width of 285mm on the back tires and that means they are wider than the i4 body. And that's illegal in I think most countries. Therefore BMW added some sort op "lip" to solve that problem.
Maybe you can buy that lip as an addition to your 868Ms...,

The 862 20” don’t need the lip?

No, because they "only" have 255mm in the back

The 862i wheels are 20x8.5et35, 20x9et42; no need for rear fender flares to properly fit inside the fenders. You can see it in the photo above.

The fender lip is required not because of the width of the rear 275 tires of the 868m wheels, but because of the 39 offset of the rear 10” 868m wheels. Alpina runs 285-20 tires in 10” wheels in their B4 Grand Coupe without flares, but the wheels have an offset of 50, or 11mm more inside the fenders than the 868m.

Well, you're right, but so am I...hehehe....The fact that the tires are so wide they exceed the width of the car, is why there is that famous lip. If the tire were only 245 wide, but with a placement more to the outside, you would also need a lip... right?
So, small offset of large offset, if the tires exceed the width of the car, you will need that lip. All depends on how the rimes are made.

You can fit 285 tires in the rear without fender flares, and they will not poke unless the offset of the 10” wheel is aggressive (40 and below). See above.

Right! exactly what I mean, but without using the word offset

My ex-bro in law once (looooong time ago) wanted to be smart someday, and he turned the wheels in side out. In the back that was no problem, but in the front, the wheels touched the chassis, with the result that he could not make a proper turn...

But here's something I just noticed: the 868M wheels are no longer available in the Dutch Price List of November 2022...
Wonder why...

Interesting discussion. I wonder why they are not an option in the US (and I am guessing maybe in some other countries too?).
Maybe that’s why we don’t see them a lot in reviews… it’s a shame because as I mentioned, they seem to offer a good compromise between looks and performance (at least on paper).
In conclusion, nobody knows anything about their range?

normal 4 series yes (no air dampers in the rear -> enough space). But the i4 with air dampers...

For those interested, I finally found a review (in French) with the 862 20" wheels.

The range seems impressive : more than 500km. Anyway, happy with my choice... can't wait to finally drive this beast!
