Is anyone running 20s,
20x9 et25
20x10 et40

More concerned about clearance to strut tower and being able to try to run as flush as possible.
Any help would be appreciated.

Bump. Wondering the same

20 x 9 et25 should essentially run the same as 19x9 et25.
There are multiple examples of the 19x9 e25 on here.

Here is a 20x9 et18 (can be accomplished by adding a 7mm spacer to the 20x9 et25 if need be).

I'd say 20x9.5 e25 is also possible but cutting it close.

The real issue with 20s are the tire profiles. These are what cause ppl to rub on the fenders even with stock suspension.

Very helpful , thank you.

In this instance of the 20" wheels (Front 9J et18 / Rear 10J et25) ,
would these exact offsets be the same for another brand/style of wheel ?

In other words , if I find a set of wheels I like and order them 20/9/et18 and 20/10/et25 , would I get the exact same fitment ? As far as where the face of the wheel lines up with the fender ?

And as far as people with 20s rubbing, do you think if I went with a less aggressive tire width , such as 245f , 265r , it would possibly alleviate this issue ?

Looks like the setup that Apex sells and recommends is:

20/9 et25 and 20/10 et38

I’m not sure but I am thinking of going with a 255/35/20 front
275/30/20 rear

Are you xDrive ?

If so, looks like we'll have to run 245 / 275

[capturedbysebastian]

No I’m not xdrive that’s why

So hard to find tires and they are quite pricey. Not trying to up in your business but would you consider 19s. 20s look a little out of place imo

[capturedbysebastian]

These are some 20s on the front, they didn’t look that bad.

I apologize for the late response. I missed this post.

1) Yes, all wheels should have the same fitment when it comes to the face of the wheel's outer most point, and the mounting spot (inner most point).
The profile of the spokes could be wildly different however, and this is where brake clearance becomes an issue for some.

2) Yes, a lower profile tire would alleviate the issue.
However, it also depends on the offset of the wheel. As a lower offset would mean, more poke OR more horizontal push of the wheel into the fender at full lock.

For example this post has 265/30/20 tires on 20x9 et30.

However, with a 15mm spacer, his final offset is et15 which causes the rubbing at full lock, NOT due to vertical tire size increase, but due to the horizontal poke.
If the spacer is reduced from a 15mm to a 12mm, then he would end up with a 20x9 et18 which (increases wheel well clearance by about 3mm) would most likely alleviate rubbing.
