I am sure this is addressed somewhere, but I can't find the answer.

I have an M235 with aftermarket wheels 18 x 8 on each corner.

I want to run Federal RS PRO 255's in the back and 245s in the front.

Will this fit?

I have seen a video on YT with a guy running this setup, but I think he has spacers.

Do any of you guys know if these will fit and if so if I need spacers? Will 255's work on 8-inch wheels?

If there is already an answer for this, please point me in that direciton.

255s on 8 inch wheels is outside manufacturers recommendations, and fitting 245s in the front is quite possible but highly dependent on the offset of the wheels.

Getting better answers will require finding out what the exact offset of your wheels are. It is usually stamped on the the wheel somewhere, typically on the hub or the back of one of the spokes. Your front and rear offsets may be (probably are) different as well.
