No issues whatsoever. I would do 255s instead of their recommended 245

Thanks so much for the reply dude I’m kinda new to like tires and rims sizing and just bmw stuff in general, did you lower your car or anything I’m thinking of H&R springs but New York roads are pretty bad

Don't do HR springs, you'll end up with a harsh ride and wear out your stock struts faster. Save up for coil overs like kw v1s or street comforts. Or do koni yellows with eibachs.

Im not lowered but I have the m sport suspension and I'm rwd so my car sits a tad lower than the xdrive from factory.

255s 40s squared has no rub, I can't speak to being lowered.

Thanks

FWIW, I am on Dinan springs on my 2017 340 xdrive with the 18x9 ARC8 and had a slight rub up front at full lock and a slight rub out back on suspension compression when running Michelin PSAS3 in 255/40. I switched to the 245 that Apex recommends and haven't had a problem since. I know a lot of guys run the 255/40 with no problem but it doesn't always work. Maybe that model tire was slightly bigger or it was something with my car, I don't really know, but I do know that switching to the recommended size fixed the problems for me.

Yeah that was my fear I’m getting Michelin Pilot Sport A/S 4 and I heard they are like thicker than other tires. Thanks for the response I appreciate it!!

Those are the tires I am running now in the 245 with no problems at all. And, while I know everyone has a different eye for style, these look more appropriate to me. Whatever you choose I am certain you will be thrilled with the new look and performance. Good luck!

Sure thing, and FWIW if I had it to do over I would not change anything…I'm very happy with the setup.

It's been done, but fitment is tight. Here is it on 8.5 width wheel:

Will also bulge more on an 8" wheel.

I think 235/45 is better:

Front tire on the blue looks off, almost like a bad photoshop. Wheels end up looking like 17". Just my opinion.
