OEM 666 rims with larger size tires?

MathewM4 · 07-31-2022, 10:38 AM

I am currently have run flats oem tires on the 666 rims.

How much larger can I go?

Would 275/30/20 front and 295/30/20 rear fit without any issues?

Rears should be fine but you'll probably rub on the fender liner for the fronts.

Ok, thanks.

I run those sizes on my M4 and I do not have any rubbing issues. It will also depend on the tires manufacturer because there are variances in width despite the numbers. I have PS4S FYI

Ok, I haven't decided on what brand to get. Michelin is always a safe bet.

Do you have any pictures of yours with the wider tires?

They rub on M3 but not the M4 as far as I know

I had 666 wheels with stock height with 285/30/20 up front and 295/30/20 in the rear with zero issues. MPS4S

Ropes · 07-31-2022, 06:12 PM

I am currently out of town and do not have pictures. I have been on those sizes for the past 50k+ miles

50K, is that one the same set of tires? If so, it is very impressive.

Ropes · 08-01-2022, 08:40 AM

I wish. Same sizes but that is 2 fronts and 3 rear sets I believe.

krudmunk · 08-10-2022, 01:23 PM

All depends on your drop and spacer sizes. 275 front is ok if you only run no spacer or 5mm up front. 295 rear has no issues and also done and did and confirmed by many.

I just installed 305's on the back of my M4 and it looks amazing. No drivability issues so far. Michelin 4S. Who needs spacers?

sergzz · 08-10-2022, 09:41 PM

I have 295 on the back, fits perfectly. 265 up front, same thing.
Can't speak on 275 from experience in the front but it should fit.

Here is a picture from the back with 295.

Just like you're doing now, I spent some time on looking into this. The general takeaway for me is if you take the chart (attached link), look at the max recommended for the rim size and add 10mm, you'll get the rough max that will fit with a very high degree of certainty.

Feel free to post a picture. I really would like to see your setup.

I have 666M with 275/30R20 front and 295/30R20 rear Continental ExtremeContact Sport XL on an M3C lowered with Eibach Euro v1 all around. Never rubbed once anywhere.

I am looking at the Continental Extreme Contact in the same size.

How do you like them?

Comparable to the Michelin?

sergzz · 08-12-2022, 08:52 AM

OP - here is a picture with the apex wheels. Not the best picture, but I just got them installed and don't have too many yet.

Hey sorry man I was inaccessible for a while. I like them a lot. Haven't really had the chance to push them like I did the P4S but so far so good. More rubber = less harsh feel and less noise on the 20s.

JipperII · 09-25-2022, 04:24 PM

Hey guys, reading up...I'm looking to swap to mich AS4s with 265s in the front and either 295s or 305s in the back.

Will I have any benefits or issues with either the 295s or 305s? I'm trying to get my setup to about 600whp and want to make sure I'm putting down enough traction.
