I got class in 2 minutes so I can't be using the search button, please a single quick response will help immensely.

What is the biggest, absolute maximum size 18" rim and tire that will fit in the rear wells of the RX-8?

 

None of you knowitalls knows ?

 

Talk about going from bad to worse.

If I knew, I'd tell ya. If I personally wanted to know, I'd do a search. And if I wanted to get genuine advice and speedy responses, I wouldn't be a d!ck about it.

Have fun.

 

I have heard of people putting 255's & 275's on it. Though I think for all around sizing front & back your best bet is to go for the 245/40/18's unless you are going staggered.

 

And to what Fanman said....245/40/18 fit on the stock rims.
