Will 285 30 19 tires fit properly on the rear stock 19x9s without rubbing? I am running on the stock m sport package suspension.

For the fronts I am wanting to use 235 35 19 on the stock 19x8 rims.

Thanks,
Mark

Hi there,

A 285/30-19 will be far too wide of a tire size to run on a 19x9" wheel. That tire size is more suited for a 10" or even a 10.5" wide wheel. Typically for a 9" wide wheel, you do not want to run anything larger than a 255 wide tire. While you could technically mount a wider tire to that wheel, that tire would not have an ideal amount of sidewall support and therefore would not have a proper contact patch. This would result in a significant drop in performance and tire wear longevity.

With that being said, typically a 275/30-19 tire size and wider will require fender rolling to fit properly without rubbing on a 335is. Specific tire selection, ride height, and wheel size/offset will also be contributing factors as to what tire sizes you can run without rubbing.

Hope this helps!

I really appreciate the thorough response... I am planning to install coilovers to adjust height to my liking... the front is a finger higher up front, compared to the rear..... so I want to atleast even them out and my thought was if I do that, then the 285s would have more room to fit. I really just want a taller and wider tore. I don't like that they look stretched... and ride is real rough with the tires being RFTs adds to that ride.

Maybe these are too wide, but how will addinng a coil over KW kit, change what options i can use to get closer to my desired result?

Thanks in advance!

Always happy to help a fellow enthusiast!

The factory 335is wheels and RFT's do not offer a comfortable ride. Installing coilovers and reducing your ride height will make it significantly more noticeable. The best way to address the ride compliance issue is by dropping down to an 18" wheel with a non-RFT using a taller sidewall. Even if you kept the same wheel and tire width, the smaller diameter wheel and taller sidewall would help make the setup not appear as "stretched" as it is currently.

Coilovers will not increase clearance for wider tires. The only modifications that would potentially help you fit 285 tires in the rear are rolled fenders and additional rear negative camber. That being said, I still would not recommend running a 285 tire on a 9" wheel.

Something along the lines of this fitment would more than likely get you to where you want to be with this car:

Front: 18x9" ET30 or ET31 with 245/40-18 tires
Rear: 18x10" ET33 with 275/35-18 tires

Hope this helps!

I'm running 235 front and 275 rear on my 313s. I would have preferred 265 but they didnt have them in stock at the time.

Currently sitting on my stock (sport) suspension. Some pictures for reference:

REAR:

I would do the coilovers first and establish your ride height. Only then will you be able to figure out your offset and tire sizes. BTW, why the need to install the largest possible tires? It only invites potential issues with ride quality and rubbing suspension and bodywork.

Thanks a bunch for the feedback Expert@ApexRaceParts ! I am thinking if I go to the 275 30 and 235/35 that will get me what I want, tire size wise...? This is the exact set up you have right ky0u you seem to have a pretty good clearance there on the same stock sport suspension I have... your first Photo is of the front right?? I see the bigger gap as I have..

As far as the coil overs, I mainly want to also maybe improve ride comfort, and be able to lower the front, or raise up a little on the rear.. Basically be able to not have the current huge gap in the front. Makes the car look like I have a hundred cement bags in the trunk, and a little more noticeable when the top is down... as you can see in the photo of my car.. Mark

Good idea on the coilovers... and I still getting them anyway, but looking at ky0u his is on the stock suspension as mine is and still has a similar gap clearance as I do... but the tires do not appear stretched with his 275/30 and 235/35 combo as I do with my stock 255/30 and 225 35 stocks.

Yup!

275/30 rear
235/35 front

And yea, the first Pic (with doggy) is my front wheel

265 on the rear is still also good, it would make the profile look like how my fronts look. 275 just juts out very slightly more than the rim and so it protects the lip a little more
