225/45s or 235/40 are fine front & back. Best to keep same all round.

The only bother you're likely to experience is finding tyres of that size with the correct load ratings.

Generally, RX8s cone with 87 or at best, 91 rated tyres. Junk them. They split around the inside wall.

DO NOT SCRIMP & SAVE ON THE LOAD RATINGS!

92 front, 96 back is what you need but that rubber don't come cheap.

The different size tyre thing only really applies when standard 15" wheels are fitted.

Once any other size wheels are fitted the standard recommendation is irrelevant.
