Will a 245/40/18 tire fit on the rear?
Hello:
I'm looking to move away from the PSS when they expire. I want to get something with more grip in the dry (at the sacrifice of grip in the wet), but the tire only comes in 245/40/18 rather than 245/35/18. I know it will decrease the gap between the tire and fender by 22.5 mm, but I was wondering if this would be a problem? I'm on an all stock setup. Thanks! |

More dry grip than PSS? What tire are you looking at?
I'm curious too about the 245/40/18, for me though it would be all the way around on the xdrive M235i with 7.5" wheels. I don't mind a little more sidewall, the stock are just tiny anyway. Tire selection is terrible if you stay with what BMW put on. |

I'm looking at the Yokohama ADVAN Neova AD08R. It has mediocre wet grip, but I live in SoCal, so it never rains. However, it does have superior dry grip to the PSS (but less treadlife). I measured it out, and it should fit, and Tirerack told me it should be fine (but they can't guarantee it). I'll ask a mechanic or something.
I'm not in a rush anyway - I'm running the PSS until they die. |

Yoko Advan ADo8's came standard on my 370Z. They are garbage. Loud, rough ride, only ok-ish dry traction, and dangerous in the rain. Shot by 13.5k I replaced them with Bridgestone S-04's and they are better in every way. sidewall is a little soft, but not too bad. By all accounts the PSS is better than the S-04's so I doubt you'll find the Yoko's to be better.

If it gives you a better idea, we test-fitted 255/35/18 RS3s on 9.5 ET50.. no rub on stock suspension

Just realized the Yoko Advan's that were oem on my 370Z are not the Neovo's you are looking at! sorry 'bout that. Still I think Bridgestone RE-11's or S-04's or your PSS will be better than the the Yoko's.
BTW if you do go with 245/40 post some pics so we can see how they fit |

if you want more grip go with a wider tire... try a 265/35 or 275/30.. make sure your wheel widths and offset are on point and get it stuffed under the fender
The RS-3 are great, once heated, but they dont get up to ideal temperatures driving to and from starbucks.. you really have to press them.. and they are quite sketchy in the wet |

I spoke to my local tire guru, and they informed me that 255/35's will fit the OEM (rear) wheels just fine. In order to keep the stock stagger, I will probably move to 235/40 and 255/35.
Also, I think I'm going to go for the Dunlop Direzza II Star Specs - my Uncle (who used to race BMWs) has them on his E36 M3 and he really likes them. I'll post pics so you guys can check them out. |

So I called my friendly tire guru and asked about a 235/40 - 255/35 setup. He said that the 235's in the front are a no no- need to stick with the 225/40's in the front, but I can move to the 255/35's in the back. So, my stagger is going to increase by 10mm. How is this going to affect handing? I suppose it might increase understeer by a little bit (the back is "stickier" than the front) but I can't imagine it would make that much of a difference from stock. Anyone have any insight? Thanks. |

You'll end up pushing even more than stock (which is a lot)... I'm pretty sure 235's will be ok in the front. Perhaps try another tire guy... Patrick |

Okay, I sent an email out to a BMW specialist that I know of in LA and see what he says. I'll post when I get a response.

Okay, new plan. I talked to my guy. He said they should fit fine, but he recommended getting a set of rear wheels (18x8) and putting them in the front for a 255/35 square setup. He has a contact at Bimmerworld he's going to check this out with. I think a square setup would probably be the best possible solution.

I'm a bit late to this thread but I've got 245/40/18 BFG Rivals on the rear of my 228 with no issues whatsoever, they're just as wide as an RS3 or ZII Starspec. For the sake of autocross I'm looking at running 245's all the way around next year with some camber plates but whether or not I'll be able to pull that off is something I'll have to find out next year. I'd love to do a square setup with 255's all the way around but I'm not sure what kind of tricks I'd have to do to get those to fit up front.
