Maximum wheel dimensions for S14?

Anyone know the maximum wheel and tire dimensions for a S14? ie tire width and wheel diameter? Would 255 be too wide?

For the S14
19" wheels may rub and I would only suggest maybe a 18" at most. Size and Offset for Front is 8" w/ +32 offset, Rear is 9" w/ +38 offset. This may not fit w/ Coilovers and a 5mm spacer is needed. Therefore your tires should not excied the width of the rim.

I'm thinking that may be to wide. I was looking at a Ferrari 360 Spyder yesterday they had 245's. It may be pushing it, but I believe you could use spacers. ;)
