235/40/18 front and 245/40/18 rear

Am going from the stock 17 inch wheels and RFTs to 18 inch non-RFTs on my 335i coupe.
Just ordered the 18 inch m sport 193 wheels which are 18 x 8 front and 18 x 8.5 rear. Problem is the bridgestone doesnt have the R001s in 255 or wider/35/18s in my country. Will I have any problem running 235/40/18 front and 245/40/18 rear tires. I know the diameter is slightly taller and the speedometer will read slightly slower (I dont care).
Please no comments about why not 19s (our roads are pretty bad)
Thanks for reading this..

how about 265 at the rear?

Suppose you can feel it, the car may become less understeering. Or it would be more oversteering. It is all relative, right? It depends on how you drive it and how you feel it. Am I making sense at all?

Since it is narrower, there shouldn't be any fitting problem. Sure 245 can go on 8.5 wheels.

I would go with 225/40/18 up front.
That keeps the front and rear closer to factory spec and stops the traction light from keep cutting in.

Thanks for the responses. I guess they should fit without problems. My next question is more with aesthetics in mind: would the rears, being only 245s look a little narrow (a little pushed in within the wheels arches) or would the the difference from stock be negligible (other than looking a little taller).

Teri: PMed you. The ebay number for the type 193 wheels is 180249307425
