What is the max tire size anyone has fitted in the front?
I am going to try to run out to Dallas for the next bmwcca event to get some seat time on some borrowed r comps and need to figure out what size to run up front.

I am working on getting my car to Vorshlag this week sometime so we can hopefully find this out, as well as enable Terry to take measurements to see if they can make a camber plate for the stock springs.

Nice to know that someone is going to be looking at this sooner rather than later. Post up when you know more.

Ken o has 4 285's on 18's but I find a couple of 275's I think for the front.

So you think the 285's will work with a spacer?

Ok.. Sorry for the delay on this... Still waiting for Terry to let me know when to show up for measurements on the camber plates.. I will ping him again..In the meantime.. went to my friend Ken O's house this past weekend with my BONE stock 1M. No camber plates..no suspension.. bone stock! We decided to test fit wheels and tires on my car... He has several sets of wheels.. All wheels are 18 x 10 APEX ARC-8. We test fit and dropped the car down..sorry... no rolling around... no driving.. First off.. we decided to go big. 285/30/18 Hoosier A6 the good.. Rear fits easy.. 305s anyone? Maybe even bigger on an 11" wheel if one wants to go crazy.. Front seems to fit fine with respect to the fender.. the tire does stick out 1" further than the body work. there appeared to be no issues contact with the spring/perch. the bad... The front tire rubbed.. ever so slightly on the inside front wheel well as the wheel was turned towards full lock - The part of the innerwheelhouse that rubs is in the front bumper, right wherre there is a radiator/cooler... left side.. right side.. the ugly.. - Dunno.. Oddly.. the panel where this radiator/cooler is in the wheelhouse is in a spot that seems to move naturally. Slight pressure on the panel allows it to move in away fom the tire. While the movement inward from the tire was minimal at rest.. this could ugly at speed at full lock.. Especially if one were attemping to autocross. Could one possibly use 5-10 mm spacers and have success? yes.. but the 285/18 tire on a 10" wheel is already outside the front fenders.. so would only look more odd in that regard. they stick out a lot though... rear clearly one can go WAYYY wider in the rear.. Next up.. we went with a Street tire. Hankook Ventus RS3 275/35/18 The Hankook is a very rounded street tire. In many ways it actually fit WORSE than the 285/30 Hoosiers. -the good.. - well.. none. -the bad... - this tire has shoulders on it due to it's being so round, and there was much less room at the spring perch... could poss rub... And turning the wheel..DEFINITE contact was made with the front inner fender wheelhouse with the the cooler in it. -The ugly - Don't go there with this tire.. Or very likely you will cause damage to inner wheelhouse parts 275/35/18 Hoosier While a set of these was mounted and available.. I feel confident that these should fit. Maybe not 100$ confidence.. but enough that this weekend we will go ahead and bolt a set of these on the car and see how they do at an autocross. If they do ok this weekend.. then I will pick up some Continental Tire/Grand Am cup takeoffs for DE use. The rim width appears to play a clear factor in whether or not there is contact between the tire and the front inner wheelhouse. For those that want to maintain a staggerred setup.. 18 x 9.5 front and 18x 10.5 rear is the easy way to go to avoid issues. more tire on a 1/2" wider wheel. I personally am hoping to be able to rotate tires, as well as utilize several wheels of the same size.. so I am going to push forward with seeing what fits on 18x10 all around.

? umm... no? I'm too cool for school..
learn what? I will see if Ken's wheels with the 275/35s fit this weekend at an autocross.. if so.. then I'll be buying up as many takeoffs as I can stack in the garage.. lol. That will set me up for TWS. Are you referring to the "false economy" of used tires? These are for DE.... and a set of takeoffs from TMS or Bimmerworld... at $350 set... vs... $350 APIECE.. Yeah.. I'm gonna go cheap for a bit.. |

265/35/18 will fit on the front, but most tires will rub on the inner fender liner on or near full steering lock. 275/35/18 will also fit with a little bit more rub. Every car is a little different so you may or may not rub on the liner with yours. |

Thanks mark. Ken sent the photo of the front today. I am real hopeful for the 265 / 19's from Hoosier after seeing it.

Thanks to Franklin for bringing his wheels and tires up to TWS on Saturday. We were able to succesfully mount four 18 x 10 Apex ARC-8s with 275/35/18 Koni Challenge ( rebadged Hoosier) tires on my car. My car is bone stock... no spacers were needed.. I did two sessions on track with the tires.. no curb hopping as this track is not really conducive to that... after two sessions including some parking lot manuevers, I am happy to report no evidence of rubbing anywhere... even with the 10" rims up front. |
