Post YOUR E89 Wheel & Tire Questions and Photos With Specs

Digging through tons of threads is a bummer. Especially when you still don't find an answer to your question. Could someone consolidate them all into one thread? It would also be handy if everyone would post pics of their Z4s with suspension, wheel and tire specs here in one place for reference?

My question is:

I want to stay with a square setup on my 30is with Eibach Pro springs, but go a little wider and +1. I've had staggered setups on previous cars, and, while it looks great, it sucks to not be able to rotate tires. So I'm thinking 18x8.5 et30 with 245/35 or 235/40 tires. Is there any fitment issue with these? I like that the 235 is slightly taller.

I'd like them to look as flush as possible. Will I need a spacer in the back? If so, what size, and will I need longer lug bolts?

Thanks in advance.

Current specs 17x8, 225/45R17 with Eibach Pro springs. Pretty boring right now.
