PSS Fitment
Is anyone running Michelin PSS in this size on a Z4M without rubbing? I'm debating 245/275 VS 235/265. Will eventually lower car slightly and probably go with coilovers.
275/30/19 on 9.5 ET 22 245/35/19 on 8.5 ET 35 Thanks! Salty

Just to share my own experience:
I used to have 245/275 [9.0 x 19 ET31 F, 10.0 x 19 ET25 R] on stock suspension. 245F rubbed lightly on full lock in the inner wheel well. 275R no rub I've had to downsize to 235/265 [8.5 x 19 ET32 R, 9.5 x 19 ET28 R] with KW CS coilovers. 235F still experience light rubbing on bumpy roads; 265R no rub I think you should be fine stock; Fitment with coilovers should be ok too but that will mostly depend on the coilovers you get.

The 265/235 are backordered right now, but I think I'll just wait it out until they are back in stock. Thanks again! Salty

For those of you running 19x10 ET 25 on the rears with 265/30 Michelin PSS tires, do you think I could get away with running 19x10 ET 20 with 265/30 PSS. Five more millimeters to the outside edge than your current setup?
I tried my best to get accurate measurements, but it is tough measuring a curved fender well. I measured from the INSIDE of the fender to the WIDEST part of the sidewall, and I've got basically no extra space, but of course on the Contis I have, the sidewall is curved, so there is more room near the outside edge of the tire. Maybe I would have 7mm or so of extra space allowing for the smaller tread width to sidewall. I get about 12mm extra space to the OUTSIDE edge of the fender to the widest part of the sidewall. Sound about right to you guys? 265/30/19 PSS Tire to Stock 19x10 ET 20 +15MM Possible Rubbing on lowered car 19x10 ET 25 +10MM Best Fitment. No rubbing on lowered car. 19x9.5 ET 22 +13MM Possible slight rubbing with aggressive driving on lowered car. Maybe would clear barely? 275/30/19 PSS Tire to Stock 19x10 ET 20 +20MM Beyond Outer Fender 19x10 ET 25 +15MM Possible Rubbing on lowered car. 19x9.5 ET 22 +18MM Beyond Outer Fender. Does this sound right? The rear wheel I'm considering comes in 19x9.5 ET 22 or 19x10 ET 20. I'd rather have the 10" wheel if I can get away with it with a 265 tire. I don't want to go lower width than a 265 on a 10" tire. I found this old post from dubsesd where he was running 19x9.5 ET 23 with 275 tires, and it's lowered, but I don't know what brand of tire he was running back then or if he used negative camber to achieve it. http://www.zpost.com/forums/showthread.php?t=636922 Using this calculator shows that a 19x9.5 ET 23 wheel on 275/30 tire that fit for Dubsesd's car is actually wider than a 19x10 ET 20 wheel on a 265/30 tire. So, I'm hopeful. Man, this wheel and tire fitment is a chore. I feel like I'm back in school, and that's been a long time. I have searched and searched and studied and used tire and wheel calcs, etc. I imagine ya'll are probably sick of tire/wheel questions. Sorry. :-( I'm late to the party, I know. Thanks for any help. Salty

This is a quick flyby, so I haven't dug into the data for you, but maybe this spreadsheet would offer some help?

I was measuring in poor light last night. I went back and re-measured. Original post updated with corrected values. I tried using a plumb line. It's still hard to measure accurately.
I also found out that the wheel comes in 19x10 ET 35, so I could run a 10mm spacer and have perfect fitment. Would you go 19x10 ET 25 (with spacer) or 19x9.5 ET 22 no spacer? Is a 10mm spacer an issue? Thanks to any of our resident wheel experts. Salty

I am by no means a wheel expert, here's a pic of my fitment of my rear tire setup: 19 X 9.5 et 25 on PSS 265/30/19. Not completely flush by any means but definitely safe. I'm dropped on Eibachs. |

Oh well, I went with 19x9.5 on 275/30/19 PSS tires. We'll see how it works. Yours with the 25 offset look good. In case anyone is curious, here is a 19x10 ET 20 with a 275/30/19 PSS Tire. He was getting some rubbing. In the photo, it looks like he's past the outer fender. http://www.zpost.com/forums/showpost...&postcount=226 And here is an example of the fitment I went with, but with different wheels. Ya'll don't hate me, I went with CSLs (rep). Have always liked them and never owned a set. Maybe I'll get the wheel bug and start changing wheels every few months. http://www.bimmerforums.com/forum/sh...d-width-alert) If Inspiri was available here, I might have tried the 01 wheel if there was a good fitment.

Another example of a 19x9.5 on 275/30. Dubsesd was running 19x9.5 ET 23 here. My CSL look similar, but are 19x9.5 ET 22, so very similar fitment. What's a millimeter between friends. I also plan to drop the car about 1.5", so it should look the same in the fitment area. Can't wait to get them in and get them mounted.

A little late to the party but I'm running 10" rim and offset 25 with a 275 tire, no rubbing and my rear is lowered quite a bit.
