Looking for information regarding tire size and wheel fitment.
New wheels are:
19x9.5 et27 front
19x11 et15 rear

What is the best tire to run on these and will I need to run a spacer for flush fitment? Currently on stock ZCP suspension but subject to change in the near future.

Thanks in advance!

19x11et15 will NOT fit even with -4 deg of rear camber. An 11et25 is an aggressive setup. 11et15 not possible unless you run 5-6 deg of neg camber and a super stretched 245 mm tire, even then it still probably won’t work. Where did the 11et15 spec come from? That’s a g8x wheel fitment.

Front would be a 275 with an 8 mm spacer (would require a hub extender) or a 10 mm spacer (3-5 mm more aggressive than the common 9.5et20-22).

Appreciate the help.

Are you sure the wheels aren’t 11et25? An 11et15 would stick out 0.393” more than 11et25 with 295/30 tires is already extremely flush fitment. Also 10.5et22 is a very flush fitment with 295s.

Do you know the tire sizes that were on the wheels in single pic in the FS thread? Really need to see a side shoot to see how well they fit and how much negative camber was used.

That's the information I received, but I'll double check to be sure.
They said 245/35 front and 285/30 rear.
Hopefully it's a typo or something.

285 is a narrow tire for an 11” wide wheel. This suggests they needed a narrower tire, and probably a lot of rear camber, to make a 11et15 + 285 tire clear the fender arch/limit rubbing/contact. The 305 is the sweet spot for an 11” wide wheel but most people on the e9x M run a 295 on an 11et25 wheel because it’s a very aggressive fitment. A 10” wide is the sweet spot for a 285, possibly a 10.5” if the 285 runs wide.

I have four setups for my two e92 M3s - HRE R43 “Fall line” F 18x9.5et20 with 275s + R 18x10et17 with 285s & HRE R43 “Fall Line” F 18x9.5et20 with 275s + R 18x9.5et20 with 275s & HRE R40 F 18x9.5et20 with 275s + R 18x10et17 with 285s & HRE 446R F 19x9et18 with 245s + R 19x9.5et15 with 265s & Team Dynamics Pro Race (winter setup) F 18x8et20 with 235s and 18x9et20 with 255s. I also have f8x wheels that will fit the e9x M with
