agressive 20's , fitment guru's come in!

Firstly, I have searched.

Secondly, I want to attempt to mount the following spec'd rims on my e92 (prelci, lowered on KW V1s)

20x8.5 et 18
20x10.5 et 20

The rears I believe should be okay with a fender roll and some camber (-2.3), 265/30/20 (I am not willing to do 255's on a 10.5 ... too narrow of a tire)

The front is my concern , considering I cant do any fender work.. I'm thinking camber and a 225/35/20..

Does anyone have any experience with this setup (mainly, the front 20x8.5 et 18)?

Thanks in advanced,

Yes, that should work. I would do 255 on the rears though. It's not too narrow.

225's on the front should fit fine, wouldn't try to go much smaller, at roughly 8.75" depending on tire model that should be a good fit on an 8.5" wheel. 255s on the rear though would be too small, its only about 10" wide. Is it physically possible to put those on the wheels without the beads tearing, probably, airing it up would be pretty difficult, let alone driving on them.

265's would probably be the smallest I would try, 275's would fit more ideal, but would probably touch your fenders. Since you are planning on rolling them, I think you will be safe, it'll be close, but its one of those things where you won't know for sure until you try it.

255/30/20 will be PERFECT!!! Trust me I've done it. With that offset you are going to need all the help you can get. Your RIMS with those offsets will stick out about 11mm (approx 1/4") from the fender. Running a 265 will rub. I ran a 9.5(+21) with a 265 tire and -3 degrees of camber. With that my RIM was 2mm behind the fender and the tire still rubbed. And it is with camber, with a pull and a roll. The person that put my wheels and tires on didn't even have to use a cheater tank to air up my tire. Just a regular hose. And I did burn outs and all with mine and was perfectly fine.

This is a 255/30/20 on a 10.5 wheels

I had 8.5 et 20 up front and there was about 3mm of room to go.
With the 225 it should be doable.

The rear a 255 would be easier to make happen. Are you going to just roll the fenders or are you willing to pull aswell?

thanks for the advice! Please keep it on topic guys

Jag - Yeah, I'm going to roll and pull. Prolly go to StanceFactory to do it too..

I'm torn between a 265 and a 255.... This is my DD so I dont want to sacrifice safety..

Anyone else running 255 on a 10.5 ? I'd like to hear more feedback from people.

Thanks again.

I think if you run FK Bumpstops in the rear you can pull it off as long as you pull the back edge of the fender out enough. The guys at StanceFactory are supposed to good at making things work maybe you can get their opinion?

Here is a pic of a very common setup with spacers versus what you want to run: (people do complain of rubbing with this a bit)
http://www.willtheyfit.com/index.php...&Submit=Submit

You can see the difference in fitment here. You should be able to clear the top edge of the tire, but your fender will hit the tire if the suspension compresses enough, this is why you would probably need the FK Bumpstops to prevent the suspension from reaching that point.

Here's a pic of another setup that's known to work without rubbing often with a 255 tire compared against it:
http://www.willtheyfit.com/index.php...&Submit=Submit

You can see the diff in edge clearance here.

I road on the 255 for a while maybe almost 8 or so months. I drove to dallas on them which is about 8 hours away. And all was good. I'll agree with Dr. G if StanceFactory is doing the work talk with them and see what they will tell you. OH YEAH and fk bumpstops are a life saver!!!!

I was running a 235 on an 8.5 +20 and was perfect. With a 225 you should be fine with the +18

265 is cutting it close. Probably will need to pull your fender more then if a 255 is not an option.

I think I asked you this question before, but I order 265/30/19 tires for wheels I just got from a friend. The wheel are M3 fitment so the rear is a bit aggressive at +22 on a 9.5 inch wheel. I have a pre LCI e90 with the rear fenders rolled. Do you think Ill have any rubbing issues or should the 265/30 on the +22 offset wheel be ok? Im a bit nervous it may not fit...

From what I've learned:

255 is perfect for a 9.5" wheel (keep in mind, 255mm = 10.0")
265 will work however it will require more fender work to fit when compared to a 255 (however both will require a roll / camber and perhaps pulling of the fenders)

Oh Wow, I wasnt hoping for that answer. Well I have the 265/30s which should be arriving this upcoming week. And my rear fenders are rolled. So I hope that helps. But I do not have any other fender work and didnt plan on getting any. It was hard enough finding someone willing to even roll my fenders. I didnt think Id have to adjust camber. Looks like I have more in store then I thought. I see you have an e92, I have a pre LCI e90. DOnt they have a bit more room in the rear then an e92?
