Running wider tires

[m3kerry]

FRONT STOCK WHEEL can handle an re-11 275/30/19

The rear can handle all the way up to a 315 hoosier which should be larger in a street tire.


Im running a 255/275 setup at this point but still need to pull the hnr front sway bar to see where the setup at this point.

Over stuffing a non rcomp tire has diminishing returns.

I'm running Toyo Proxes T1-Sport in 265-30-R19 front and 295-30-R19 rear on the oem Style 359M wheels...no problem. No rub in the front at all (fender liners) and only on hard compression in the right-rear (bolt head for the rear bumper cap to 1/4 panel fitting). Fantastic look and great feel.

I have a friend locally that is running this. 265 up front on the stock wheel. 295 on rear.

That sounds like something I would like to run.

Did you install the revised fender liners, or never changed? Also I don't quite understand, by hard compression what do you mean? like a speed bump?

Another thing Im wondering is would the rear tire compromise the weight/passangers sitting in the back kind of deal? I have a feeling that with someone sitting in the back, a speed bump really means an ass bump.

Can you post a pic? I have a feeling that stance will be epic.

Nope...stock fender liners, as supplied with the car when purchased. I have a rather late production run car, being one of the last sent to Canada at #205 of the 220, so it's possible that I may have the revised parts pre-installed.

Hard compression means high-speed dip...ie: weight of the car comes down on the suspension. Speed bumps don't do it, but then again, I don't take speed bumps at speed.

I've had two passengers in the car with luggage and didn't hear anything. I've had just me in the car and hear it hit. It's all dependant upon speed and the type of bump / dip.

Can you post a pic? I have a feeling that stance will be epic.

Click on my Garage List (just below avatar and info) for the car -- there are two photos in that album that show the car with the 265-30 / 295-30 tires mounted on my black Style 359M wheels (the silver Style 359M wheels have the oem Michelins and the silver Style 270M wheels have the oem Michelin winters).

The 265/30 and 295/30 are shorter than 265/35 and 295/35 and therefore fit with far less issues than their 35 aspect ratio counterparts.

I test-fit a 265/40/18 AD08 on 18x9.5 et23 wheel up front yesterday to get a sense of how much my front wheel well can accommodate. There was rubbing with turning, maybe 70% full lock, against both front and rear fender liners. This is running -2.5 camber with revised liners.

According to Yoko's website, that tire is 10.7" in width and 26.3" in diameter, which is what the stock rear PS2s (265/35/19) measure.

A 265/35/18 (R888) comes in at 10.8" wide / 25.4" diameter, and a 275/35/18 is 11" wide / 25.7".

Is rubbing more likely to happen because a tire is too wide or too tall?

On both the front and rear, you will run first run into issues when going too tall. I wouldn't use a 40 series sidewall on any 18 or 19. I would only use 35 or 30. The 275/35/18 will fit and protrudes menacingly out from the wheel wells with my 10" wheels. I would think yours would tuck in closer to the body work and look closer to stock. I have photos showing this in another thread, " max tire size fitted to the front."

I've been running Hoosiers A6s in the following sizes:
265/35-19 They rub the liners a little bit.
315/30-19 in the rear. The clear without contact.
OEM wheel sizes but with a ¼" offset increase all the way around

Are you sure that's not a 265/35 ? (I couldn't find the a 265/30 in Hoosier's catalog to look up the specs.)

Last week I test fit a friend's 275/35/18 RE-11s (Apex ARC8 18x9.5 et 22) on my front axle and did not notice any audible rub (-2.5 camber, revised liners.)
Emboldened, I just put on some 275/35/18 NT01s on 18x9.5 et23 219M wheels. There's a slight amount of rub on both the front and rear liners in the front wheelwell based on visual inspection. I can't hear or feel any rub from inside the car, though. Good to go, I think ...

I forget, are you on stock suspension / camber?
To only have slight rubbing with a 265/35/19 is impressive.
The rub I had with a 265/40/18 (which as far as I can tell has ~ identical diameter) was pretty noticeable.
Then again, I read somewhere that liners are considered a wear item

[mattm]

As close to stock as I can be. I had prepped the car to SCCA Solo Stock rules. OEM spring seats and springs, but KW V3s stuffed inside. It keeps the springs at the correct ride height and legal for the class (Stock classification goes away 1/1/2015). Camber is a hair under -2° up front and just about -2° in the rear. Yeah, my liners are a wear item. They already warrantied them once. I can't press it again especially since they just warrantied a clutch replacement and pads and rotors all the way around.

So, more ProSolo starts?

GJ and I were kind of tough on the clutch in 2013 at the DC Pro. After the Saturday morning session, the smell of toasty clutch was quite prevalent. We took it easy from there. I noticed some slip on the way back from the Meadowlands two weeks ago.

If I want to get 1 set of rims that works with both race rubber and winter rubber, I'm thinking ARC-8 18x9.5 ET22, using 235/40R18 Michelin Arctic Alpin PA3 for winter but square 275/35R18 Hankook R-S3 for track how bad will the rubbing be? Hankook is that much cheaper than anything else that it's worthwhile as a 3rd set of tire (in addition to the stock summers) - I know that on 18x10 the 275/35R18 R-S3 will rub in the front but 18x9.5 will make the tires narrower

I'm not a fitment expert, but that seems like it would be very stretched.

Regarding rub, I've haven't found a reliable way to predict this.

For reference, a friend running 275/35/18 RE-11s on 18x9.5 et22 ARC8s on a 1M had noticeable rub at about 75% of full lock in reverse (~-2.0 camber)

The same wheel on my car (-2.5 camber) + revised liners did not noticeably rub. 275/35/18 NT01s on 18x9.5 et23 219Ms rub very slightly on my car.

[CP 1///M]

The other option is to go quite a bit shorter with 285/30R18 but I don't think Hankook R-S3 come in that size (Dunlop ZII or BFG R1 do) and I think someone ran BFG R1 at that size on 18x10 ARC-8 with fairly minimal rubbing (if at all)

[ayao]

I think a reasonable alternative would be to consider 265/35/18 square?

RE-11, ZII, AD08R, R-S3 all available in that size ...

That would be me. 285/30-18 BFG R1 fits with no issues on my apex 18x10 wheels. My car also does have camber plates but is stock with the original fender liners.


275/35/18 fits as well.
