I have 135i M package.
Is is okay with use this set up?
Front: 215/40/18
Rear: 255/35/18.
I already replaced a front tire with Continental Extreme Contact all season same size as RFT. I can't find all season tire for rear 245/35/18 so i decide to go with 255/35/18 instead.
Is is really okay to go with this setup?

I would recommend going to a 225 width tire up front as well.

I am about to purchase these tires. Should I go with the stock 215/40, 245/35 sizes or the wider 225/40, 255/35 sizes on the stock 261m 18" wheels?

I already purchased the front tire, so i don't have choice for now.

No, it is not. Especially when in a staggered fitment.

Go with the 255/35 size in the DWS. That's what we have on our 135i, but in the 225/40 size in front.

It'll be fine, and more importantly, your speedo / odo accuracy will improve, as the stock tire sizes cause the gauges to read very optimistic.
