285/30ZR18 at the rear ?
 

Anybody using 285/30ZR18 on 18x9.5 ET45 at the Rear on an RX-7 FD. Please let me know as I intend of using them ???

Not sure what your asking.. but I run 18x9.5 in the rear w/ 285/35 tires

tire size
 

I'm running 285x30x18 on the rear and 225x35x18 on the front.
i have no problems with them.

I've got 285/30-18 on all four corners with CCW 18x10" wheels with 7.5" backspacing (measured) and coil-overs. I was amazed when I put them on this weekend at the track and got ZERO rubbing. I do have the screws that hold the fender liner on the top of the wheel arches in front removed. I also had the ride height up to stock-ish levels, -0.8 camber at each corner, and stiff 550/450 springs with stock bars. It seems like there is a lot of room in the back, though, and I would not expect any rubbing with the car lowered.

Thanks for your replies guys, now I know that they fit.
