Hi there,

On the E9X non-M chassis, the most popular square 17" setup we see runs the following specs:

Front & Rear: 17x9" ET30 with 245/40-17 tires
-Direct fit.
-255/40-17 can be used but may require front negative camber.
-5mm front spacers may be required with certain aftermarket suspensions

With a 17x9" ET30 wrapped in 245/40-17 tires at all four corners, this setup will be a direct fit on a stock or lowered non-M E9X. As a wider alternative, you can also run 255/40-17 tires but in some cases with more aggressive compounds, a touch of additional negative camber may be required. However, with all-seasons, you might be able to get away without any additional front camber, as long as your ride height isn't set too low.

Hope this helps!
