Will 20 inch (square 9j 32) be okay for M340i?

benzp7 · 05-18-2023, 01:29 AM

Previously owned Audi S6.
Moved onto M340i recently and been loving it. However, I do not like the design of the stock wheel and want to replace it with the wheel I used to use from Audi, which is 20-inch wheel with 9j et32 (66.5).

My question is would this be okay to rock if I just put like 245 Front / 265 Rear? I think the size of the tires are fine but in terms of having same offset wheels, will this cause any headache?

Thank you!

If you’re xDrive, make sure you have <1% rolling diameters

Try willtheyfit.com. It’ll show you a comparison between your current setup and the new one.

And as the previous poster said, stay within a 1% difference in rolling diameter (wheel+tire) if you have an xDrive vehicle.

BMW makes a 20” factory wheel & tire combo made just for the G20’s with correct off sets. Somewhere around $4k depending on dealer where you order. A few guys on these forums are running them. Look really nice.
