Now on the 18x9, I can go with a 255/35R18 or a 245/40R18. I think with the 255/35 setup I might have to add spacers if I upgrade the suspension. I think the 245/40 would have more clearance on the suspension, but also be more likely to require rolling the fenders.
Does anybody have experience with either of these setups and can recommend what to go with?
Thanks

Hi there,
On a stock E9X 335i X-drive, you can run a 18x9" ET30/31 at all four corners with a 255/35-18 tire as a complete direct fit. 5mm front spacers are typically only required when running an aftermarket coilover suspension that is known to reduce inner clearance (KW, ST, etc). With either a 245/40-18 or a 255/35-18, you should not need to roll your rear fenders with stock suspension. However, I would lean towards the 255/35-18 as you get some additional grip without needing to modify anything to do so.
If you have any other questions please feel free to reach out!
