2007 335i E92 with stock suspension.
Currently I'm on 265/35R18 PSS on the rears with my APEX ARC-8 18x9.5 ET35.
I don't rub, but what will I have to do to fit 275/35R18 Federal RSRR's?
I've heard they're typically wider than most tires and will rub.

Will just a bit of fender rolling make this setup work? I got these tires for a really good price.

Thanks

I was in the same dilemma as you, I think you might be able to fit those 275 rs rr's with little to no modifications because of your higher wheel offsets and stock suspension.

I made the decision of running 265 rs rr's on my E92. My wheel spec is 18x9.5 et 22 + i'm lowered + rear fenders are rolled, I only rub on big dips cause the rs rr's shoulders are much more squared.

An 18x9.5" ET35 wheel wrapped in a 275/35-18 tire that runs wide (most r-comps and slicks) will require a minimum of 5mm spacers up front to clear your factory suspension, as well as a healthy amount of negative camber to ensure you do not rub the outer front fenders under suspension compression. Purchasing and installing adjustable camber plates would be required, as pulling your factory camber pins will only net you about -1.8 degrees.

Some enthusiasts have stretched a 245 tire on the 18x9.5" ET35 and therefore have avoided the need for spacers and camber up front, but there is really no reason to go this route when we have our concave 18x9" ET30 wheel available which suits 245 and 255 tires much better.

In the rear, we would encourage you to dial in somewhere between -1.8 and -2.2 degrees of camber, which is essentially maxing things out with your factory components. At stock ride height, you may not have to roll your fenders.

This is an aggressive wheel and tire fitment for the front of the E9X non-M chassis, and typically only used on a prepared track/race car. Enthusiasts running this square setup are looking to maximize front and rear grip with the ability to rotate wheels and tires on all four corners, and would typically have upgraded suspension with a healthy amount of negative camber dialed in to ensure they can leverage the wheel and tire setup. There are a lot of benefits to dialing in negative camber to performance driving enthusiasts, so this should not be perceived as a negative thing.

For customers predominantly enjoying their car on the street, an 18x9" ET30 square fitment with 255/35-18 tires makes a lot more sense as this setup does not require spacers or camber (or anyone of our staggered fitments if the goal is to run a wider tire out back).

That definitely sounds like what OP is trying to do, but thanks for sharing that other info as well

Ha! I totally missed the fact that OP was only asking about the rear fitment Lesson learned, never respond to threads before coffee.

Go for it OP. As mentioned the rear fitment is much simpler and at stock ride height may not even require a roll or additional negative camber.

Haha, all is good. Thanks for the information provided, I will throw on the 275/35 RSRR's which reportedly run like 285's whenever my set of PSS tires wear out.

Thanks again for your help!

Bump.. did you end up putting 275 in the rear?
