How wide I can go with 18x8 +40???

Hi guys, I might get a set of 18x8 +40 wheels for track duties. I need to know how wide I can go on tires.

I have M3 suspension bits on the way, if that influence the outcome.

Thanks

235/40. Anything wider is a waste of time on an 8" wheel. Even then, a 225 is better suited to an 8" wheel...

Will 235 be enough for track porpoise?

I have not bought the wheels yet, but the price is pretty good.

Thanks BTW
